Abstract
BACKGROUND Prediabetes, which is a precedent of overt diabetes, is a known risk factor for adverse cardiovascular outcomes. Its impact on adverse cardiovascular outcomes in patients with cancer who are prescribed anthracycline-containing chemotherapy (ACT) is uncertain. The objective of this study was to evaluate the association of prediabetes with cardiovascular events in patients with cancer who are prescribed ACT. METHODS The authors identified patients with cancer who received ACT from 2000 to 2019 from Clinical Data Analysis Reporting System of Hong Kong. Patients were divided into diabetes, prediabetes, and normoglycemia groups based on their baseline glycemic profile. The Primary outcome, a major adverse cardiovascular event (MACE), was the composite event of hospitalization for heart failure and cardiovascular death. RESULTS Among 12,649 patients at baseline, 3997 had prediabetes, and 5622 had diabetes. Over median follow-up of 8.7 years, the incidence of MACE was 211 (7.0%) in the normoglycemia group, 358 (9.0%) in the prediabetes group, and 728 (12.9%) in the diabetes group. Compared with normoglycemia, prediabetes (adjusted hazard ratio [HR], 1.20; 95% confidence interval [CI], 1.01-1.43) and diabetes (adjusted HR, 1.46; 95% CI, 1.24-1.70) were associated with an increased risk of MACE. In the prediabetes group, 475 patients (18%) progressed to overt diabetes and exhibited a greater risk of MACE (adjusted HR, 1.76; 95% CI, 1.31-2.36) compared with patients who remained prediabetic. CONCLUSIONS In patients with cancer who received ACT, those who had prediabetes at baseline and those who progressed to diabetes at follow-up had an increased risk of MACE. The optimization of cardiovascular risk factor management, including prediabetes, should be considered in patients with cancer who are treated before and during ACT to reduce cardiovascular risk. PLAIN LANGUAGE SUMMARY Patients with cancer who have preexisting diabetes have a higher risk of cardiovascular events, and prediabetes is often overlooked. In this study of 12,649 patients with cancer identified in the Clinical Data Analysis Reporting System of Hong Kong who were receiving treatment with anthracycline drugs, prediabetes was correlated with increased deaths from cardiovascular disease and/or hospitalizations for heart failure. Patients who progressed from prediabetes to diabetes within 2 years had an increased risk of combined hospitalization for heart failure and death from cardiovascular disease. These findings indicate the importance of paying greater attention to cardiovascular risk factors, including how prediabetes is managed, in patients who have cancer and are receiving chemotherapy with anthracyclines, emphasizing the need for surveillance, follow-up strategies, and consideration of prediabetes management in cancer care.

Abstract
Background Heart failure (HF) and dementia frequently co-exist with shared pathological mechanisms and risk factors. Our study aims to investigate the association between statin therapy and the risks of dementia and its subtypes among patients with HF. Methods The Hong Kong Clinical Data Analysis and Reporting System database was interrogated to identify patients with incident HF diagnosis from 2004 to 2018, using ICD 9/ICD 10 codes. Inverse probability of treatment weighting (IPTW) was used to balance baseline covariates between statin users (N = 54,004) and non-users (N = 50,291). The primary outcomes were incident all-cause dementia, including subtypes of Alzheimer's disease, vascular dementia, and unspecified dementia. Cox proportional-hazard model with competing risk regression was performed to estimate the sub-distribution hazards ratio (SHR) with corresponding 95% confidence intervals (CI) of the risks of all-cause dementia and its subtypes that are associated with statin use. Findings Of all eligible patients with HF (N = 104,295), the mean age was 74.2 ± 13.6 years old and 52,511 (50.3%) were male. Over a median follow-up of 9.9 years (interquartile range [IQR]: 6.4-13.0), 10,031 (9.6%) patients were diagnosed with dementia, among which Alzheimer's disease (N = 2250), vascular dementia (N = 1831), and unspecified dementia (N = 5950) were quantified separately. After IPTW, statin use was associated with a 20% lower risk of incident dementia compared with non-use (multivariable-adjusted SHR 0.80, 95% CI 0.76-0.84). Stratified by subtypes of dementia, statin use was associated with a 28% lower risk of Alzheimer's disease (SHR 0.72, 95% CI 0.63-0.82), 18% lower risk of vascular dementia (SHR 0.82, 95% CI 0.70-0.95), and a 20% lower risk of unspecified dementia (SHR 0.80, 95% CI 0.75-0.85). Interpretation In patients with HF, statin use was associated with a significantly lower risk of all-cause dementia and its subtypes, including Alzheimer's disease, vascular dementia, and unspecified dementia. Both randomized trials and experimental studies to validate the potential neuroprotective effect of statin are warranted. Funding No funding was provided for this study.

Abstract
AIMS To investigate the risk of hyperkalaemia in new users of sodium-glucose cotransporter 2 (SGLT2) inhibitors vs. dipeptidyl peptidase-4 (DPP-4) inhibitors among patients with type 2 diabetes mellitus (T2DM). METHODS AND RESULTS Patients with T2DM who commenced treatment with an SGLT2 or a DPP-4 inhibitor between 2015 and 2019 were collected. A multivariable Cox proportional hazards analysis was applied to compare the risk of central laboratory-determined severe hyperkalaemia, hyperkalaemia, hypokalaemia (serum potassium ≥6.0, ≥5.5, and <3.5 mmol/L, respectively), and initiation of a potassium binder in patients newly prescribed an SGLT2 or a DPP-4 inhibitor. A total of 28 599 patients (mean age 60 ± 11 years, 60.9% male) were included after 1:2 propensity score matching, of whom 10 586 were new users of SGLT2 inhibitors and 18 013 of DPP-4 inhibitors. During a 2-year follow-up, severe hyperkalaemia developed in 122 SGLT2 inhibitor users and 325 DPP-4 inhibitor users. Use of SGLT2 inhibitors was associated with a 29% reduction in incident severe hyperkalaemia [hazard ratio (HR) 0.71, 95% confidence interval (CI) 0.58-0.88] compared with DPP-4 inhibitors. Risk of hyperkalaemia (HR 0.81, 95% CI 0.71-0.92) and prescription of a potassium binder (HR 0.74, 95% CI 0.67-0.82) were likewise decreased with SGLT2 inhibitors compared with DPP-4 inhibitors. Occurrence of incident hypokalaemia was nonetheless similar between those prescribed an SGLT2 inhibitor and those prescribed a DPP-4 inhibitor (HR 0.90, 95% CI 0.81-1.01). CONCLUSION Our study provides real-world evidence that compared with DPP-4 inhibitors, SGLT2 inhibitors were associated with lower risk of hyperkalaemia and did not increase the incidence of hypokalaemia in patients with T2DM.

Abstract
BACKGROUND The nonuniform benefit of tricuspid annuloplasty may be explained by the proportionality of tricuspid regurgitation (TR) severity to right ventricular (RV) area. The purpose of this study was to delineate distinct morphological phenotypes of functional TR and investigate their prognostic implications in patients undergoing tricuspid annuloplasty during left-sided valvular surgery. METHODS The ratios of pre-procedural effective regurgitant orifice area (EROA) with right ventricular end-diastolic area (RVDA) were retrospectively assessed in 290 patients undergoing tricuspid annuloplasty. Based on optimal thresholds derived from penalized splines and maximally selected rank statistics, patients were stratified into proportionate (EROA/RVDA ratio ≤ 1.74) and disproportionate TR (EROA/RVDA ratio > 1.74). RESULTS Overall, 59 (20%) and 231 (80%) patients had proportionate and disproportionate TR, respectively. Compared to those with proportionate TR, patients with disproportionate TR were older, had a higher prevalence of atrial fibrillation, lower pulmonary pressures, more impaired RV function, and larger tricuspid leaflet tenting area. Over a median follow-up of 4.1 years, 79 adverse events (47 heart failure hospitalizations and 32 deaths) occurred. Patients with disproportionate TR had higher rates of adverse events than those with proportionate TR (32% vs 10%; P = 0.001) and were independently associated with poor outcomes on multivariate analysis. TR proportionality outperformed guideline-based classification of TR severity in outcome prediction and provided incremental prognostic value to both the EuroSCORE II and STS score (incremental χ2 = 6.757 and 9.094 respectively; both P < 0.05). CONCLUSIONS Disproportionate TR is strongly associated with adverse prognosis and may aid patient selection and risk stratification for tricuspid annuloplasty with left-sided valvular surgery.

Abstract
Diagnosing heart failure with preserved ejection fraction (HFpEF) remains challenging. Intraventricular four-dimensional flow (4D flow) phase-contrast cardiovascular magnetic resonance (CMR) can assess different components of left ventricular (LV) flow including direct flow, delayed ejection, retained inflow and residual volume. This could be utilised to identify HFpEF. This study investigated if intraventricular 4D flow CMR could differentiate HFpEF patients from non-HFpEF and asymptomatic controls. Suspected HFpEF patients and asymptomatic controls were recruited prospectively. HFpEF patients were confirmed using European Society of Cardiology (ESC) 2021 expert recommendations. Non-HFpEF patients were diagnosed if suspected HFpEF patients did not fulfil ESC 2021 criteria. LV direct flow, delayed ejection, retained inflow and residual volume were obtained from 4D flow CMR images. Receiver operating characteristic (ROC) curves were plotted. 63 subjects (25 HFpEF patients, 22 non-HFpEF patients and 16 asymptomatic controls) were included in this study. 46% were male, mean age 69.8 ± 9.1 years. CMR 4D flow derived LV direct flow and residual volume could differentiate HFpEF vs combined group of non-HFpEF and asymptomatic controls (p < 0.001 for both) as well as HFpEF vs non-HFpEF patients (p = 0.021 and p = 0.005, respectively). Among the 4 parameters, direct flow had the largest area under curve (AUC) of 0.781 when comparing HFpEF vs combined group of non-HFpEF and asymptomatic controls, while residual volume had the largest AUC of 0.740 when comparing HFpEF and non-HFpEF patients. CMR 4D flow derived LV direct flow and residual volume show promise in differentiating HFpEF patients from non-HFpEF patients.

Abstract
The utilization of FFR remains low. Our study evaluated the per-vessel prognostic value of computational pressure-flow dynamics-derived FFR (caFFR) among patients with stable coronary artery disease. A total of 3329 vessels from 1308 patients were included and analysed. They were stratified into ischaemic (caFFR ≤ 0.8) and non-ischaemic (caFFR > 0.8) cohorts, and the associations between PCI and outcomes were evaluated. The third cohort comprised all included vessels, and the associations between treatment adherent-to-caFFR (PCI in vessels with caFFR ≤ 0.8 and no PCI in vessels with caFFR > 0.8) and outcomes were evaluated. The primary outcome was VOCE, defined as a composite of vessel-related cardiovascular mortality, non-fatal myocardial infarction, and repeat revascularization. PCI was associated with a lower 3-year risk of VOCE in the ischaemic cohort (HR, 0.44; 95% CI, 0.26-0.74; P = 0.002) but not in the non-ischaemic cohort. The risk of VOCE was lower in the adherent-to-caFFR group (n = 2649) (HR, 0.69; 95% CI, 0.48-0.98; P = 0.039). A novel index that uses coronary angiography images to estimate FFR may have substantial clinical value in guiding management among patients with stable coronary artery disease.

Abstract
OBJECTIVES The benefit of sodium-glucose cotransporter 2 (SGLT2) inhibitors in reducing the occurrence rate of adverse cardiac and renal outcomes in patients with type 2 diabetes has been well described in randomized trials. Whether this benefit extends to patients at the most severe end of the disease spectrum requiring admission to the ICU remains to be examined. DESIGN Retrospective observational study. SETTING Data were obtained from a territory-wide clinical registry in Hong Kong (Clinical Data Analysis and Reporting System). PATIENTS All adult patients (age ≥ 18 yr) with type 2 diabetes and newly prescribed SGLT2 inhibitors or dipeptidyl peptidase-4 (DPP-4) inhibitors between January 1, 2015, and December 31, 2019. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS After 1:2 propensity score matching, a total of 27,972 patients (10,308 SGLT2 inhibitors vs 17,664 DPP-4 inhibitors) were included in the final analysis. The mean age was 59 ± 11 years, and 17,416 (62.3%) were male. The median follow-up period was 2.9 years. The use of SGLT2 inhibitors was associated with decreased ICU admission (286 [2.8%] vs 645 [3.7%]; hazard ratio [HR], 0.79; 95% CI, 0.69-0.91; p = 0.001) and lower risks of all-cause mortality (315 [3.1%] vs 1,327 [7.5%]; HR, 0.44; 95% CI, 0.38-0.49; p < 0.001), compared with DPP-4 inhibitors. The severity of illness upon ICU admission by Acute Physiology and Chronic Health Evaluation IV-predicted risk of death was also lower in SGLT2 inhibitors users. Admissions and mortality due to sepsis were lower in SGLT2 inhibitor users compared with DPP-4 inhibitor users (admissions for sepsis: 45 [0.4%] vs 134 [0.8%]; p = 0.001 and mortality: 59 [0.6%] vs 414 [2.3%]; p < 0.001, respectively). CONCLUSIONS In patients with type 2 diabetes, SGLT2 inhibitors were independently associated with lower rates of ICU admission and all-cause mortality across various disease categories.

Abstract
Abstract
Aims
Heart failure with preserved ejection fraction (HFpEF) continues to be a diagnostic challenge. CMR atrial measurements, feature-tracking (CMR-FT), tagging have long been suggested to diagnose HFpEF and potentially complement echocardiography especially when echocardiography is indeterminate. Data supporting the use of atrial measurements, CMR-FT or tagging is absent. Our aim is to conduct a prospective case-control study assessing the diagnostic accuracy of CMR atrial volume/area, CMR-FT, and tagging to diagnose HFpEF amongst patients suspected of having HFpEF.
Methods & Results
121 suspected HFpEF patients were prospectively recruited from four centres. Patients underwent echocardiography, CMR, NT-proBNP measurements within 24 hours to diagnose HFpEF. Patients without HFpEF diagnosis underwent catheter pressure measurements or stress echocardiography to confirm HFpEF or non-HFpEF. Area under the curve (AUC) were determined by comparing HFpEF with non-HFpEF patients. 53 HFpEF (median age 78yrs, interquartile range 74-82yrs) and 38 non-HFpEF (median age 70yrs, interquartile range 64-76yrs). CMR left atrial (LA) reservoir strain (ResS), LA area indexed (LAAi) and LA volume indexed (LAVi) had the highest diagnostic accuracy (AUCs 0.803, 0.815 and 0.776 respectively).
LA ResS, LAAi and LAVi had significantly better diagnostic accuracy than CMR-FT left ventricle (LV)/right ventricle (RV) parameters and tagging (p < 0.01). Tagging circumferential and radial strain had poor diagnostic accuracy (AUC 0.644 and 0.541 respectively).
Conclusion
CMR LA ResS, LAAi and LAVi have the highest diagnostic accuracy to identify HFpEF patients from non-HFpEF patients amongst clinically suspected HFpEF patients. CMR-FT LV/RV parameters and tagging had low diagnostic accuracy to diagnose HFpEF.

Abstract
AIM To investigate the interplay of incident chronic kidney disease (CKD) and/or heart failure (HF) and their associations with prognosis in a large, population-based cohort with type 2 diabetes (T2DM). METHODS Patients aged ≥18 years with new-onset T2DM, without renal disease or HF at baseline, were identified from the territory-wide Clinical Data Analysis Reporting System between 2000 and 2015. Patients were followed up until December 31, 2020 for incident CKD and/or HF and all-cause mortality. RESULTS Among 102 488 patients (median age 66 years, 45.7% women, median follow-up 7.5 years), new-onset CKD occurred in 14 798 patients (14.4%), in whom 21.7% had HF. In contrast, among 9258 patients (9.0%) with new-onset HF, 34.6% had CKD. The median time from baseline to incident CKD or HF (4.4 vs. 4.1 years) did not differ. However, the median (interquartile range) time until incident HF after CKD diagnosis was 1.7 (0.5-3.6) years and was 1.2 (0.2-3.4) years for incident CKD after HF diagnosis (P < 0.001). The crude incidence of CKD was higher than that of HF: 17.6 (95% confidence interval [CI] 17.3-17.9) vs. 10.6 (95% CI 10.4-10.9)/1000 person-years, respectively, but incident HF was associated with a higher adjusted-mortality than incident CKD. The presence of either condition (vs. CKD/HF-free status) was associated with a three-fold hazard of death, whereas concomitant HF and CKD conferred a six to seven-fold adjusted hazard of mortality. CONCLUSION Cardiorenal complications are common and are associated with high mortality risk among patients with new-onset T2DM. Close surveillance of these dual complications is crucial to reduce the burden of disease.

Abstract
OBJECTIVE To investigate for potential protective effects of statin use among patients with infective endocarditis (IE) with consideration for underlying diseases and bacterial culture - variables which have prognostic implications and show considerable geographic variation yet are unappreciated in previous pharmacoepidemiological studies. PATIENTS AND METHODS Patients diagnosed with IE between January 1, 1996, and December 31, 2019, were identified. We estimated the effect on mortality of pre-admission statin use (≥90 cumulative days of use before index date) and in-hospital use (use beginning within 2 days of admission), compared with nonusers and discontinued users, respectively, through propensity score analytics. RESULTS Of 6700 IE patients (mean age, 58.0 years; 63.3% male [n=4251]), 776 patients had pre-admission statin use, with 626 continuing statin use following admission (in-hospital users). Pre-admission statin users had a 31% lower risk of 1-year mortality (HR, 0.69; 95% CI, 0.58 to 0.82) compared with nonusers. In-hospital users had a 48% lower risk of 1-year mortality (HR, 0.52; 95% CI, 0.34 to 0.78) compared with discontinued users. Subgroup analyses showed significant protective effects of statin use for patients with varying causative agents, underlying diseases, and with or without prosthetic valves. Results were consistent across different statins, and were dose-dependent. CONCLUSION In patients with IE, pre-admission and in-hospital use of statin, when compared with statin nonusers and discontinued users, respectively, were associated with a lower risk of 1-year mortality.

Abstract
Background Heart failure (HF) may increase the risk of dementia via shared risk factors. Objectives The authors investigated the incidence, types, clinical correlates, and prognostic impact of dementia in a population-based cohort of patients with index HF. Methods The previously territory-wide database was interrogated to identify eligible patients with HF (N = 202,121) from 1995 to 2018. Clinical correlates of incident dementia and their associations with all-cause mortality were assessed using multivariable Cox/competing risk regression models where appropriate. Results Among a total cohort aged ≥18 years with HF (mean age 75.3 ± 13.0 years, 51.3% women, median follow-up 4.1 [IQR: 1.2-10.2] years), new-onset dementia occurred in 22,145 (11.0%), with age-standardized incidence rate of 1,297 (95% CI: 1,276-1,318) per 10,000 in women and 744 (723-765) per 10,000 in men. Types of dementia were Alzheimer's disease (26.8%), vascular dementia (18.1%), and unspecified dementia (55.1%). Independent predictors of dementia included: older age (≥75 years, subdistribution hazard ratio [SHR]: 2.22), female sex (SHR: 1.31), Parkinson's disease (SHR: 1.28), peripheral vascular disease (SHR: 1.46), stroke (SHR: 1.24), anemia (SHR: 1.11), and hypertension (SHR: 1.21). The population attributable risk was highest for age ≥75 years (17.4%) and female sex (10.2%). New-onset dementia was independently associated with increased risk of all-cause mortality (adjusted SHR: 4.51; P < 0.001). Conclusions New-onset dementia affected more than 1 in 10 patients with index HF over the follow-up, and portended a worse prognosis in these patients. Older women were at highest risk and should be targeted for screening and preventive strategies.

Background
Prosthetic valve endocarditis (PVE) is a rare but serious complication following valvular heart surgery for which preventive strategies remain unknown. Recent epidemiological evidence suggests that statins may reduce the risk of infections and infection-related complications.
Purpose
We aim to assess the association between statin use and the risk of prosthetic valve endocarditis in patients undergoing valvular heart surgery.
Methods
In all patients undergoing valvular heart surgery in Hong Kong between 2010 and 2021, statin use was ascertained by ≥14-day consecutive filled prescriptions after surgery. Stepwise Poisson regression was applied to identify predictors of PVE. Baseline characteristics between statin nonusers (N = 1400) with statin users (N = 976) were balanced using the inverse probability of treatment weighting. Cox proportional-hazard models with competing risk regression were further performed to estimate the risk of PVE and cardiovascular mortality associated with statin use.
Results
Our study included 2376 patients; the mean age was 57.8±14.2 years, and 54.4% were males. Over a median follow-up of 5.5 years (interquartile range 2.8-8.6), PVE occurred in 93 patients (6.75 [95% CI 5.51-8.26] PVE events per 1000 person-years). PVE was associated with New York Heart Association Class (Relative Risk [RR] 1.22, 95% Confidence Interval [CI] 1.01-1.45; P = 0.035), prior infective endocarditis (RR 8.64, 95% CI 5.58-13.19; P < 0.001), and aortic valve replacement (RR 1.67, 95% CI 1.11-2.53; P = 0.014).
Compared with non-use, statin use was associated with a 47% lower risk of PVE incidence (multivariable-adjusted subdistribution hazard ratio [SHR] 0.53, 95% CI 0.33-0.83; P = 0.006) (Figure 1). This inverse association with the risk of PVE was duration dependent, with an adjusted SHR of 0.60 (95% CI 0.47-0.73; P < 0.001) per year of statin use. Results were consistent across subgroups of sex (male vs female), the number of valvular procedures (single vs multiple), and prosthesis type (mechanical vs biological), but not in groups aged ≤60 years or with prior infective endocarditis (Figure 2). Statin use was associated with a 45% decreased risk of cardiovascular death (SHR 0.55, 95% CI 0.36-0.84; P = 0.006).
Conclusions
In patients undergoing valvular surgery, post-operative statin use is associated with a lower risk of PVE. These results provide new avenues for preventing PVE and hence valve failure.

Background
Hyperkalemia is a common complication and increases the risk of cardiac arrhythmias and mortality in patients with type 2 diabetes (T2DM), especially in those with diabetic nephropathy. We investigated the risk of hyperkalemia in patients initiated on SGLT2 inhibitors versus DPP-4 inhibitors among patients with T2DM.
Methods
This study included patients with T2DM who initiated on SGLT2 inhibitors or DPP-4 inhibitors between January 01, 2015 and December 31, 2019 from a territory-wide clinical registry in Hong Kong (Clinical Data Analysis and Reporting System [CDARS]). A multivariable cox proportional hazards analysis, adjusting for key confounders, was used to compare the risk of central laboratory-determined hyperkalemia (serum potassium ≥6.0mmol/L) and hypokalemia (serum potassium <3.5mmol/L), respectively, between SGLT2 inhibitors and DPP-4 inhibitors.
Results
10193 new users of SGLT2 inhibitors were matched to 17305 new users of DPP-4 inhibitors. During the 2-year follow-up, there were 104 hyperkalemia events (incident rate [IR] = 5.17 per 1000 person-years) among SGLT2 inhibitors and 306 events (IR = 9.09 per 1000 person-years) among DPP-4 inhibitors, of which SGLT2 inhibitors were associated with a lower risk of incident hyperkalemia (Adjusted HR: 0.66 [95%CI 0.53-0.83], p<0.001), compared to DPP-4 inhibitors. The incident hypokalemia was similar between SGLT2 inhibitors and DPP-4 inhibitors (Adjusted HR: 0.91 [95%CI 0.81-1.03], P=0.13).
Conclusion
SGLT2 inhibitors reduced incident hyperkalemia, but without increasing incident hypokalemia compared to DPP-4 inhibitors.

Abstract
OBJECTIVE To evaluate the association between prediabetes and heart failure (HF) and the association of HF with changes in glycemic status. RESEARCH DESIGN AND METHODS Patients newly diagnosed with atrial fibrillation (AF) between 2015 and 2018 were divided into three groups (normoglycemia, prediabetes, and type 2 diabetes) according to their baseline glycemic status. The primary outcome was incident HF. The Fine and Gray competing risks model was applied, with death defined as the competing event. RESULTS Among 17,943 patients with AF (mean age 75.5 years, 47% female), 3,711 (20.7%) had prediabetes, and 10,127 (56.4%) had diabetes at baseline. Over a median follow-up of 4.7 years, HF developed in 518 (14%) patients with normoglycemia, 646 (15.7%) with prediabetes, and 1,795 (17.7%) with diabetes. Prediabetes was associated with an increased risk of HF compared with normoglycemia (subdistribution hazard ratio [SHR] 1.12, 95% CI 1.03-1.22). In patients with prediabetes at baseline, 403 (11.1%) progressed to diabetes, and 311 (8.6%) reversed to normoglycemia at 2 years. Compared with remaining prediabetic, progression to diabetes was associated with an increased risk of HF (SHR 1.50, 95% CI 1.13-1.97), whereas reversion to normoglycemia was associated with a decreased risk (SHR 0.61, 95% CI 0.42-0.94). CONCLUSIONS Prediabetes was associated with an increased risk of HF in patients with AF. Compared with patients who remained prediabetic, those who progressed to diabetes at 2 years experienced an increased risk of HF, whereas those who reversed to normoglycemia incurred a lower risk of HF.

Abstract
Background Circulating thrombospondin-2 (TSP2) levels were associated with the development of heart failure (HF) in recent studies. However, these studies included only a minority of patients with type 2 diabetes, which is associated with an increased HF risk. As hyperglycemia induces TSP2 expression and its tissue expression increases in type 2 diabetes, we investigated the prospective association of circulating TSP2 with incident HF hospitalization (HHF), and its associations with longitudinal changes of echocardiographic parameters in type 2 diabetes. Methods Baseline serum TSP2 levels were measured in 4949 patients with type 2 diabetes to determine its association with incident HHF using multivariable Cox regression analysis. In the echocardiographic study, baseline serum TSP2 levels were measured in another 146 patients with type 2 diabetes but without cardiovascular diseases who underwent detailed transthoracic echocardiography at baseline and after 1 year. Results Over a median follow-up of 7.8 years, 330 of 4949 patients (6.7%) developed incident HHF. Baseline serum TSP2 levels were independently associated with the development of HHF (HR 1.31, 95%CI 1.06–1.62, p = 0.014) after adjustments for baseline conventional cardiovascular risk factors, atrial fibrillation, estimated glomerular filtration rate, albuminuria and high-sensitivity C-reactive protein level, use of angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, loop-diuretics, aspirin, insulin, metformin and sodium-glucose co-transporter 2 inhibitors. Moreover, baseline serum TSP2 levels were independently associated with increase in average E/e’ and left atrial volume index (p = 0.04 and < 0.01, respectively). Conclusion Serum TSP2 levels were independently associated with both incident HHF and deterioration in diastolic function in type 2 diabetes.

Abstract
BACKGROUND Insulin-treated patients with long duration of type 2 diabetes mellitus (T2DM) are at increased risk of ketoacidosis related to sodium-glucose co-transporter 2 inhibitor (SGLT2i). The extent of circulating ketone elevation in these patients remains unknown. We conducted this study to compare the serum ketone response between dapagliflozin, an SGLT2i, and sitagliptin, a dipeptidyl peptidase-4 inhibitor, among insulin-treated T2DM patients. METHODS This was a randomized, open-label, active comparator-controlled study involving 60 insulin-treated T2DM patients. Participants were randomized 1:1 for 24-week of dapagliflozin 10 mg daily or sitagliptin 100 mg daily. Serum β-hydroxybutyrate (BHB) levels were measured at baseline, 12 and 24 weeks after intervention. Comprehensive cardiometabolic assessments were performed with measurements of high-density lipoprotein cholesterol (HDL-C) cholesterol efflux capacity (CEC), vibration-controlled transient elastography and echocardiography. RESULTS Among these 60 insulin-treated participants (mean age 58.8 years, diabetes duration 18.2 years, glycosylated hemoglobin 8.87%), as compared with sitagliptin, serum BHB levels increased significantly after 24 weeks of dapagliflozin (P=0.045), with a median of 27% increase from baseline. Change in serum BHB levels correlated significantly with change in free fatty acid levels. Despite similar glucose lowering, dapagliflozin led to significant improvements in body weight (P=0.006), waist circumference (P=0.028), HDL-C (P=0.041), CEC (P=0.045), controlled attenuation parameter (P=0.007), and liver stiffness (P=0.022). Average E/e', an echocardiographic index of left ventricular diastolic dysfunction, was also significantly lower at 24 weeks in participants treated with dapagliflozin (P=0.037). CONCLUSION Among insulin-treated T2DM patients with long diabetes duration, compared to sitagliptin, dapagliflozin modestly increased ketone levels and was associated with cardiometabolic benefits.

Abstract
Abstract
Objective
Severe aortic stenosis (AS) is the primary valvular heart disease, treatable only by aortic valve replacement (AVR). The prognostic value of pre-operative left atrial (LA) function on post-AVR clinical outcomes is uncertain. The study aims to evaluate the prognostic value of pre-operative peak atrial longitudinal strain (PALS) as a surrogate of LA function on post AVR all-cause mortality and heart failure hospitalisation.
Methods
Patients aged 18 years old or above with severe AS were recruited and assessed using speckle-tracking echocardiography pre-operatively. Severe AS was defined according to 2014 AHA/ACC Guideline for the Management of Patients with Valvular Heart Disease. PALS was measured. Based on the median value of PALS, patients were stratified into PALS <15.94% and PALS >15.94%. Patients with underlying pre-operative atrial fibrillation, other moderate to severe valvular heart diseases and cancers were excluded. Patients were followed up until death, heart failure hospitalisation or end of the study. The primary outcome is a composite endpoint of all-cause mortality and heart failure hospitalisation. The association of PALS with the composite endpoint was evaluated by Cox Proportional Hazards analysis.
Results
A total of 128 patients (mean age 65.32±9.42 years, 56.3% male) were prospectively analyzed. Patients were followed up for a mean period of 3.9±2.4 years. A total of 65 of 128 patients (50.8%) belonged to PALS<15.94%. During the study period, 23 patients developed the adverse events. A lower pre-operative PALS, both as a continuous or a categorical variable, were associated with a higher unadjusted risk of adverse events (Continuous; HR, 0.93; 95% CI 0.88–0.98; p=0.011; PALS <15.94%; HR, 4.94; 95% CI, 1.67–14.58; p=0.004).
Conclusion
The study demonstrated a lower pre-operative PALS is associated with all-cause mortality and heart failure admission in patients with severe AS undergoing AVR. Evaluation of LA function by assessing speckle tracking derived PALS may aid in prognostication for patients undergoing AVR.

Abstract
AIM The organ protective effects of sodium-glucose cotransporter 2 (SGLT2) inhibitors may be beneficial against infectious complications. This real-world study aims to compare the risk of pneumonia and sepsis between SGLT2 inhibitors and dipeptidyl peptidase 4 (DPP-4) inhibitors in patients with type 2 diabetes. METHODS Using a territory-wide clinical registry in Hong Kong (Clinical Data Analysis and Reporting System [CDARS]), we included patients initiated on SGLT2 inhibitors or DPP-4 inhibitors between January 01, 2015 and December 31, 2019 through 1:2 propensity score matching. The primary outcomes were incident events of pneumonia, sepsis and the related mortality. Cox proportional hazards analysis was used to compare the risk of incident pneumonia and sepsis for SGLT2 inhibitors versus DPP-4 inhibitors. RESULTS After propensity score matching, 10,706 new users of SGLT2 inhibitors and 18,281 new users of DPP-4 inhibitors were included. The mean age of all eligible subjects were 60 years (SD 11.07) and 61.1% were male. There were 309 pneumonia events [incidence rate per 1000 person-years (IR) = 11.38] among SGLT2 inhibitors users and 961 events (IR = 20.45) among DPP-4 inhibitors users, with lower risk of pneumonia among SGLT2 inhibitors users (adjusted HR 0.63 [95%CI 0.55-0.72], p<0.001). Similarly, SGLT2 inhibitors users had lower incidence of sepsis [164 (IR=6.00) vs. 610 (IR=12.88) events] as well as associated risk of incident sepsis (HR 0.52 [95% CI 0.44-0.62], p<0.001), compared to DPP-4 inhibitors users. Outcome analyses showed that SGLT2 inhibitors were associated with lower risk of pneumonia-related death (HR 0.41 [95%CI 0.29-0.58], p<0.001), sepsis-related death (HR 0.39 [95%CI 0.18-0.84], p<0.05), and infection-related death (HR 0.43 [95%CI 0.32-0.57], p<0.001), compared to DPP-4 inhibitors users. Results were consistent when stratified by age, sex, pre-existing cardiovascular disease, and type of SGLT2 inhibitors. CONCLUSION We provide real-world evidence that irrespective of age, sex, prior-existing cardiovascular disease, or type of SGLT2 inhibitors used, patients with type 2 diabetes initiated on SGLT2 inhibitors have lower incidence of pneumonia and sepsis as well as mortality risk associated with pneumonia, sepsis, and infectious diseases, compared with those initiated on DPP-4 inhibitors.

Abstract
BACKGROUND AND OBJECTIVE Our recent work shows that periodontitis experience reflects host susceptibility to the onset of multiple systemic diseases and conditions. This cross-sectional study further investigated whether and to what extent the existing periodontitis could reflect the concurrent presence of inflammatory comorbidities among 'self-perceived health' individuals. MATERIALS AND METHODS There were 115 'self-perceived health' adults who completed a questionnaire on demographic characteristics and lifestyles. Twenty medical diagnostic tests were then performed to detect eight common systemic diseases and conditions. Meanwhile, full-mouth periodontal examination was undertaken, and the subjects were classified as two subgroups with or without Generalized Severe Periodontitis (Stages III/IV, generalized). The interlink of periodontal status and concurrent systemic comorbidities was assessed. RESULTS 98.3% (113/115) of the subjects exhibited at least one undiagnosed systemic disease/disorder. Of them, 52.2% (59/113) and 47.8% (54/113) concurrently presented with 1-5 or ≥6 abnormal test results, respectively. Overall, 96.5% (111/115) had periodontitis. Generalized Severe Periodontitis was present in 43.2% (48/111) of the periodontitis patients, and it was significantly associated with the profiles of abnormal test results after adjusting potential confounders (abnormal test results 1-5 vs ≥6; OR: 3.23, p = .012). CONCLUSIONS The present study shows that existing severe periodontitis could well reflect the concurrent presence of multiple inflammatory comorbidities. Oral and medical professionals can play proactive roles in enhancing health awareness and healthcare, through strong collaboration and teamwork.

Background
Heart failure (HF) is common in patients with nonvalvular atrial fibrillation (NVAF) which is associated with excess morbidity and mortality. Notably, the presence of diabetes increases risk of HF in patients with NVAF. The association between pre-diabetes and risk of HF was nonetheless unexplored in this population.
Purpose
The present study aimed to evaluate whether pre-diabetes was associated with an increased risk of HF in patients with NVAF.
Methods
Using a previously validated territory-wide electronic health record database, patients with newly diagnosed NVAF from 2010 to 2018 were included to evaluate for risk of HF upon competing risk regression with Cox proportional-hazard model adjustment. Patients were divided into 3 groups according to their baseline glycemic status: (1) type 2 diabetes, (2) pre-diabetes, and (3) normoglycemia. In the pre-diabetes group, the subsequent risk of HF was further evaluated according to the changes of glycemic status at two years following index date.
Results
Among 65,994 NVAF patients (mean age 75.7 years, 48.5% female), 27,706 (42.0%) were normoglycemic, 10,926 (16.6%) had pre-diabetes, and 27,312 (41.4%) had diabetes at baseline. Over a median follow-up of 7.1 years, 7,203 (26%) normoglycemic patients, 3,168 (29%) pre-diabetic patients, and 8,745 (32%) diabetic patients developed HF (Log rank test, P<0.001). Pre-diabetes was associated with an increased risk of HF compared with normoglycemic patients (subdistribution Hazard Ratio (SHR) = 1.09, 95% confidence interval (CI): 1.04-1.14) and diabetes conferred the highest risk amongst three groups (SHR=1.19, 95%CI: 1.15-1.24). In patients with pre-diabetes at baseline, 873 (8.0%) progressed to diabetes and 1204 (11%) resolved to normoglycemia at 2 years. Compared to those who remained pre-diabetic, patients who progressed to diabetes had a higher risk of HF (SHR = 1.23, 95% CI :1.05-1.44), whereas those who resolved to normoglycemia incurred a lower risk (SHR = 0.80, 95% CI :0.68-0.94).
Conclusion(s)
Pre-diabetes was independently associated with an increased risk of HF in patients with NVAF. Pre-diabetic patients who progressed to diabetes at 2 years experienced an increased risk of HF, whereas those who resolved to normoglycemia reduced risk of HF, as compared to those who remained pre-diabetic. These findings highlight the importance of strict blood glucose control in reducing the risk of HF in patients with atrial fibrillation.

Abstract
Background and Aim Rheumatoid arthritis is associated with both abnormal bone metabolism and accelerated vascular aging but a mechanistic link was lacking. This study aims to investigate the role of osteocalcin (OCN)-expressing circulating endothelial progenitor cells (EPCs) in vascular aging, as determined by arterial calcifications in rheumatoid arthritis. Methods We performed flow cytometry studies in 145 consecutive patients with rheumatoid arthritis to determine osteogenic circulating levels of OCN-positive (OCN+) CD34+KDR+ and OCN+CD34+ versus conventional early EPC CD34+CD133+KDR+. Total calcium load of the thoracic aorta (ascending plus descending) and the carotid arteries were assessed by non-contrast computed tomography (CT) and contrast CT angiography. Results Osteogenic EPCs OCN+CD34+KDR+ (P = 0.002) and OCN+CD34+ (P = 0.001), together with clinical parameters of age, history of hypertension, systolic blood pressure, serum levels of triglycerides, HbA1c and creatinine, use of leflunomide and brachial-ankle pulse-wave velocity (all P < 0.05), were associated with the clustered presence of aortic and carotid calcification. Multivariable analyses revealed that circulating OCN+CD34+KDR+ (B = 14.4 [95% CI 4.0 to 24.8], P = 0.007) and OCN+CD34+ (B = 9.6 [95% CI 4.9 to 14.3], P < 0.001) remained independently associated with increased aortic calcium load. OCN+CD34+ EPC (B = 0.8 [95% CI 0.1 to 1.5], P = 0.023), but not OCN+CD34+KDR+ EPC (B = 1.2 [95% CI −0.2 to 2.6], P = 0.09), was further independently associated with carotid calcium load. In comparison, conventional early EPC CD34+CD133+KDR+ had no significant association with aortic or carotid calcium load (P = 0.46 and 0.88, respectively). Conclusion Circulating level of osteogenic EPC is associated with increased vascular aging in terms of calcification of the large arteries in patients with rheumatoid arthritis. The findings may suggest a role of the bone-vascular axis underlying vascular aging in rheumatic diseases. Further research is needed to characterize the mechanistic links and basis of these observations.

Background
Patients with secondary tricuspid regurgitation (TR) benefit differentially from tricuspid annuloplasty. We hypothesized that TR severity may be proportional or disproportional to right ventricular (RV) remodeling and investigated the prognostic implication of this novel framework.
Methods
The ratios of pre-procedural effective regurgitant orifice area (EROA) with right ventricular end-diastolic area (RVDA) and tricuspid annular plane systolic excursion (TAPSE) were retrospectively assessed in 307 patients undergoing tricuspid annuloplasty. Based on optimal thresholds derived from cubic splines and maximally selected rank statistics, patients were stratified into 3 groups: proportionate TR (Group 1: EROA/RVDA ≤1.70 and EROA/TAPSE ≤3.42), disproportionate TR to RV size (Group 2: EROA/RVDA >1.70 and EROA/TAPSE ≤3.42), and disproportionate TR to RV size and function (Group 3: EROA/RVDA >1.70 and EROA/TAPSE >3.42).
Results
Overall, 77 (25%), 126 (41%), and 104 (34%) patients were classified into Group 1, 2, and 3, respectively. Compared with those with proportionate TR (Group 1), patients with disproportionate TR (Group 2 and 3) had a higher prevalence of atrial fibrillation and smaller left ventricular end-diastolic and end-systolic volumes. During a median (interquartile range) follow-up of 4.1 (2.5-6.2) years, 81 adverse events (49 HF hospitalizations and 32 deaths) occurred. Patients with disproportionate TR (Group 2 and 3) had higher rates of adverse events than those with proportionate TR (22% and 44% versus 9%; P = 0.018 and P < 0.001, respectively) and were independently associated with poor outcomes on multivariate analysis. TR proportionality outperformed guideline-based prediction algorithm comprising EROA and RV assessment in outcome prediction (C-statistic 0.70 versus 0.62, p = 0.015; likelihood ratio test <0.001).
Conclusion
Disproportionate TR is independently associated with poor prognosis in patients undergoing tricuspid annuloplasty. Characterization of TR severity to RV size and function may aid patient selection and risk stratification for tricuspid annuloplasty. Abstract Figure.

Background
Patients with secondary tricuspid regurgitation (TR) represent a heterogeneous group that benefits differentially from tricuspid annuloplasty. We hypothesized that TR severity may be proportional or disproportional to right ventricular (RV) remodeling and investigated the prognostic implications of this novel paradigm.
Methods
The ratios of pre-procedural effective regurgitant orifice area (EROA) with right ventricular end-diastolic area (RVDA) and tricuspid annular plane systolic excursion (TAPSE) were retrospectively assessed in 307 patients undergoing tricuspid annuloplasty. Based on optimal thresholds derived from cubic splines and maximally selected rank statistics, patients were stratified into 3 groups: proportionate TR (Group 1: EROA/RVDA ≤1.68 and EROA/TAPSE ≤3.42), disproportionate TR to RV size (Group 2: EROA/RVDA >1.68 and EROA/TAPSE ≤3.42), and disproportionate TR to RV size and function (Group 3: EROA/RVDA >1.68 and EROA/TAPSE >3.42).
Results
Overall, 72 (23%), 127 (41%), and 108 (35%) patients were classified into Group 1, 2, and 3, respectively. Compared with those with proportionate TR (Group 1), patients with disproportionate TR (Group 2 and 3) had a higher prevalence of atrial fibrillation, moderate to severe aortic stenosis, and smaller left ventricular end-diastolic and end-systolic volumes. During a median (interquartile range) follow-up of 4.3 (2.6-6.3) years, 74 adverse events (42 HF hospitalizations and 32 deaths) occurred. Patients with disproportionate TR (Group 2 and 3) had higher rates of adverse events than those with proportionate TR (21% and 38% versus 8%; P = 0.010 and P < 0.001, respectively; Figure) and were independently associated with poor outcomes on multivariate analysis. Importantly, this novel framework outperformed the TR grading system recommended by current guidelines, which was unable to effectively stratify prognosis in this population (Hazard Ratio for severe versus moderate TR 1.42; 95% CI 0.84-2.38; P = 0.194).
Conclusion
Disproportionate TR is independently associated with poor prognosis in patients undergoing tricuspid annuloplasty. Characterization of TR severity to RV size and function may aid patient selection and risk stratification for tricuspid annuloplasty. Abstract Figure.

Addressing pregnancy risks poses as a new challenge among women with repaired tetralogy of Fallot (TOF). The high-output state of pregnancy may predispose women to late complications of repaired TOF. However, guidelines regarding antenatal and or perinatal cardiovascular assessment has not been outlined. Noninvasive modalities such as cardiac magnetic resonance imaging (CMR) that do not require the utilization of ionizing radiation are feasible methods of assessment. Risk stratification of baseline CMR parameters has been sparsely investigated among repaired TOF cohorts. This study aims to identify baseline CMR parameters that may predict adverse outcomes of pregnancy among women with repaired TOF.
Sixty-five successful pregnancies were recorded from a cohort of 105 pregnant episodes. Patients with CMR studies performed within 5 years prior to delivery events were included. Adverse clinical outcomes of interest included arrhythmia, heart failure admissions, gestational hypertension, pre-eclampsia toxemia and all-cause mortality. Baseline CMR parameters regarding ventricular mechanics such as left and right ventricular end-diastolic and end-systolic volumes, left and right ventricular ejection fractions and pulmonary regurgitant fraction were measured, and their association with adverse clinical outcomes were evaluated using an independent-samples t-test.
Within all 65 successful pregnancies, 26 baseline CMR images were obtained and included in this study. The mean maternal age was 29.7 ± 6.7 years old with a mean birth weight of 2.91 ± 0.49 kg at a mean gestational age of 38.4 ± 2.0 weeks. There was a total of 12 patients with adverse clinical outcome: 5 patients with heart failure hospitalizations, 4 patients with gestational hypertension, 4 patients with arrhythmia and 2 patients with pre-eclampsia toxemia.
Assessment of baseline CMR parameters of ventricular mechanics revealed that increased left ventricular end-diastolic volumes (LVEDV) (144.7mL/m2 ± 4.9; P = 0.011), left ventricular end-systolic volumes (LVESV) (65.1mL/m2 ± 9.4; P = 0.004), right ventricular end-diastolic volumes (RVEDV) (235.2 ± 29.0; P = 0.021) and right ventricular end-systolic volumes (RVESV) (122.2mL/m2 ± 38.1; P = 0.033) were associated with an increased incidence of arrhythmia during pregnancy. Nonetheless, there was no significant association between baseline ventricular mechanics with heart failure, gestational hypertension, and pre-eclampsia toxemia.
Baseline assessment of cardiac magnetic resonance imaging among pregnant TOF women revealed that larger left and right ventricular volumes were associated with arrythmia development during pregnancy. Further studies with larger cohort sizes evaluating the role of antenatal and perinatal cardiovascular imaging assessment using CMR in predicting the risks of cardiovascular complications during pregnancy are warranted.

Background
Dementia, in the setting of heart failure (HF), portends poorer outcomes and poses great challenges in its clinical management.
Purpose
We investigated the incidence, types, clinical correlates, and the prognostic impact of dementia in a population-based cohort of patients with HF. Further, we examined the interactions of age and sex, and education status with dementia incidence.
Methods
The previously validated Hong Kong Clinical Data Analysis Reporting System (CDARS), a territory-wide database was interrogated to identify patients with HF (N= 202,121) from 1995 to 2018. Associations of clinical correlates with incident dementia and its risk with all-cause mortality were assessed using competing risk/multivariable Cox regression models where appropriate.
Results
Among a total cohort aged ≥18 years with HF (mean age: 75.3 ± 13.0 years, 51.3% women), new-onset dementia occurred in 22,145 (11.0%) over a median follow-up of 5.5 years. Alzheimer’s disease occurred in 27.0%; vascular dementia (18.1%) and unspecified dementia (in 55.1%). Age-standardized rate of dementia incidence in women was 1297 (95%CI, 1276-1318) (vs. 744, 95%CI, 723-765) per 10000 population in men. Other independent predictors of dementia include: Increasing age (HR 1.08), Female sex (HR 1.19), Nil/< primary (vs tertiary) education (HR 1.29), Parkinson’s disease (HR 1.73), head injury (HR 1.37), peripheral vascular disease (HR 1.31), stroke (HR 1.29), depression (HR 1.18), alcohol intake (HR1.17), anaemia (HR 1.14), hypertension (HR 1.08), among other common comorbidities in HF (Figure 1A).
Notably, a significant interaction (p < 0.001) between age and sex on dementia incidence was observed, such that women in all age groups were observed to have higher sHR compared to men (Figure 1B). After accounting for competing risk, dementia was not associated with adjusted hazard of all-cause mortality.
Conclusions
Female sex, lower socioeconomic status, increasing age and common comorbidities were associated with higher hazards of incident dementia. Abstract Figure 1A and Figure 1B

Objective
Severe aortic stenosis (AS) is the most common primary valvular heart disease, treatable only by aortic valve replacement (AVR). Current literatures have shown that severe AS may precede atrial dysfunction which predicts adverse outcomes. However, predictive value of pre-operative left atrial (LA) function on post-AVR clinical outcomes is uncertain. The study aims to evaluate the prognostic value of pre-operative LA strain on post AVR all-cause mortality and heart failure.
Methods
Patients aged 18 years old or above with severe AS were recruited and assessed using speckle-tracking echocardiography pre-operatively. Severe AS was defined according to 2014 AHA/ACC Guideline for the Management of Patients With Valvular Heart Disease. Peak Atrial Longitudinal Strain (PALS) was measured as a surrogate of LA function. Patients with underlying pre-operative atrial fibrillation and other severe valvular heart diseases were excluded. High PALS was defined as PALS higher than 15.94%. Patients were followed up until death or end of the study. The primary endpoint is a composite endpoint of all-cause mortality and heart failure during hospitalisation. The association of LA function with composite endpoint of all-cause mortality and heart failure was evaluated by Cox Proportional Hazards analysis.
Results
A total of 128 patients (mean age 65.3.9 ± 9.4 years, 56.3% male) were analysed. Patients were followed up for a mean period of 3.9 ± 2.4years. A total of 65 of 128 patients (50.8%) belonged to low PALS group. During the study period, 23 patients developed events on the composite endpoint. Among those with composite endpoint, low PALS group accounted for 18 (78.3%) patients and high PALS group accounted for 5 (21.7%) patients. Higher PALS was independently associated with lower risk of composite endpoint of all-cause mortality and heart failure (HR, 0.33; 95% CI 0.117-0.916, p = 0.03) after adjustment for EuroSCORE II.
Conclusion
Higher PALS, a surrogate of LA function, is associated with a lower risk of composite endpoints of mortality and heart failure in patients with severe AS undergoing AVR, independent of EuroSCORE II. Evaluation of LA function by assessing speckle tracking derived PALS may aid in prognostication for patients undergoing AVR.

Background
Diabetes, chronic kidney disease (CKD) and heart failure (HF) are fast-growing causes of morbidity and mortality worldwide. Diabetes is an optimal model to study the inter-play of cardiovascular disease and renal disease.
Purpose
To investigate the association of CKD with HF and its prognosis in a large, population-based cohort of diabetes, in which incident CKD and HF events were ascertained longitudinally.
Methods
A population-based cohort of patients aged ≥18 years with diabetes, but without CKD, HF or acute kidney injury at baseline was identified from the previously validated territory-wide Clinical Data Analysis Reporting System between 2000 and 2015. Patients were followed up through December 31,2020 for incident CKD and/or HF or all-cause mortality. Multi-state modelling was used to examine the association of the subgroups (with/without CKD or HF).
Results
Among 294,413 patients (mean age: 65 ± 14 years; 49.5% women), new-onset CKD occurred in 51,583, in whom one-fifth (21.3%) had HF. In contrast, among 28,335 patients with new-onset HF, nearly two-fifth (38.7%) had CKD (Figure 1A). Median duration from baseline to incident CKD was shorter than incident HF [8.27 (4.69-11.97) years vs. 8.76 (5.28-12.37) years, p <0.001]. However, median duration for incident event of HF after CKD diagnosis was 2.15 (0.83-4.50) years and 1.73 (0.62-3.87) years for incident CKD after HF diagnosis. The incidence rate of CKD and HF was 20.39 per 1000 person-years and 10.61 per 1000 person-years, respectively.
Presence of CKD was associated with incident HF (odds ratios [OR] 1.27 [95%CI 1.21-1.33]), and HF with incident CKD (OR 1.26 [95%CI 1.18-1.33]). The presence of both CKD and HF (regardless of which comes first) portends higher risk (6 to 8-fold hazards) of all-cause mortality than neither condition (Figure 1B).
Conclusions
Incident HF occurs in one-fifth of patients with new-onset CKD, and CKD occurs in about 40% with new-onset HF. CKD seems to precede HF. More research on the inter-play of these dual conditions is warranted in view of the high mortality risk. Abstract Figure.

Following advancements in intracardiac repair of Tetralogy of Fallot (TOF), a greater proportion of patients survive well beyond child-bearing age. Pulmonary regurgitation (PR) and subsequent progressive right ventricular dilatation occur frequently as an intrinsic complication of surgical repair of TOF. High-output states such as pregnancy may exacerbate these late complications. The advocation of pre-pregnancy pulmonary valve replacement to mitigate pregnancy-related cardiac burden has remained controversial. This study aims to delineate the outcomes of pregnancy among women with repaired TOF.
105 pregnant episodes among were identified from a cohort of 240 adult female patients with TOF between 1990 to 2021. Patients with echocardiographic studies performed within 1 year prior to and following delivery were included for cardiac functional analysis. A paired sample t-test was performed to compare echocardiographic parameters between pre-delivery and post-delivery periods. Linear regression was used to identify changes to identify significant changes in echocardiographic parameters among patients with a baseline of severe PR.
Within all pregnant episodes (n = 105), 65 successful pregnancies, 16 spontaneous miscarriages, 21 termination of pregnancies and 3 ectopic pregnancies were recorded. The mean maternal age was 28.9 (±6.7) years with deliveries at 37.86 (30-41) gestational weeks. Cardiovascular events occurred in 19 pregnancies with 4 patients having gestational hypertension, 4 patients with pre-eclampsia toxemia, 7 patients with heart failure symptoms and 4 patients with arrhythmias. Other complications included 4 patients with gestational diabetes mellitus, 3 patients with impaired glucose tolerance, 2 patients with anemia, 3 patients with maternal thyroid disease and 1 patients with proteinuria.
Echocardiographic studies demonstrated significant changes in left ventricular ejection fraction (LVEF) (Pre-delivery = 60.69 ±8.73; post-delivery = 59.39 ±9.36) (P = 0.007), left ventricular end diastolic volume (LVEDV) (Pre-delivery: 89.71mL ±18.22mL; Post-delivery: 80.96mL ±12.32mL; P = 0.007), left end systolic volume (LVESV) (Pre-delivery: 35.43 ±12.36; Post-delivery: 32.70 ± 8.83; P = 3.7x10-5) and right ventricular index of myocardial performance score (Pre-delivery: 0.34 ±0.12; Post-delivery: 0.33 ±0.12; P = 0.007). Patients with severe PR was found to have significantly worse right ventricular global longitudinal strain (RV GLS) (P = 0.029). 2 patients progressed to severe PR following delivery.
Adult female patients with TOF can have viable pregnancies with acceptable mortality and morbidity. Deterioration in echocardiographic parameters were identified when comparing between pre-delivery and post-delivery studies. TOF patients should be closely monitored throughout and post-delivery for detection of deterioration of cardiac function and clinical symptoms.

Abstract
Background The presence of tricuspid regurgitation (TR) is very common in patients with concomitant left-sided valve disease. Recent studies have advocated an additional grading of massive TR that is beyond severe. The present study sought to characterize the spectrum of TR in patients undergoing tricuspid annuloplasty (TA) and to evaluate the prognostic value of TR severity for post-operative outcome following TA. Methods A total of 176 patients who underwent TA with combined left-sided valve surgery, secondary to rheumatic valvular heart disease, were prospectively evaluated. The severity of TR was quantified by effective regurgitant orifice area (EROA) using the proximal isovelocity surface area method. Patients were categorized as having non-massive TR (EROA < 0.6 cm2) or massive TR (EROA ≥ 0.6 cm2). Adverse outcome was defined as all-cause mortality or heart failure requiring hospital admission following TA. Results A total of 55 (31%) patients were considered to have massive TR. Patients with massive TR had a greater right ventricular dimension but a smaller left ventricular dimension compared with those with non-massive TR. After a median follow-up of 39 months, 35 adverse events occurred. Cox-regression analysis showed that both continuous EROA and dichotomized EROA (massive vs. non-massive TR) were independently associated with adverse events even after multivariable adjustment. Further, Harrell C index demonstrated that the addition of massive TR provided better discrimination ability of a prediction model to known prognosticators following TA. Conclusions Massive TR is common and up to 31% of study population had massive TR. Massive TR was associated with adverse outcome in patients undergoing TA. Classification of the severity of TR by quantitative measures and identification of massive TR in patients with concomitant left-sided valve disease are essential when considering the optimal timing of corrective surgery.

Abstract
Abstract
Introduction
Multiple valvular heart disease, a combination of stenotic and regurgitant lesions occurring on two or more valves, is a highly prevalent condition. For these patients, surgical correction is the only definitive treatment to improve prognosis, yet concomitant aortic and mitral (double) valve surgery is associated with poor post-operative outcomes. While current guidelines outline left ventricular dimensions and function as surgical triggers, little is known regarding the importance of right ventricular (RV) remodelling in these patients.
Purpose
We sought to evaluate the prognostic value of RV remodelling in patients undergoing double valve surgery.
Methods
RV remodelling was characterised by transthoracic echocardiography in 152 patients undergoing concomitant aortic and mitral valve replacement (n=118) or aortic valve replacement and mitral valve repair (n=34). Four patterns of RV remodelling were defined according to the presence of RV dilation (tricuspid annulus diameter>35mm) and RV systolic dysfunction (percentage RV fractional area change <35%): normal RV size and systolic function (pattern 1); dilated RV with normal systolic function (pattern 2); RV systolic dysfunction with normal RV size (pattern 3); and dilated RV with systolic dysfunction (pattern 4). Adverse events were defined as the composite of all-cause mortality and hospitalisation for heart failure.
Results
Overall, 62 (41%), 31 (20%), 35 (23%), and 24 (16%) patients were classified as RV remodelling patterns 1, 2, 3, and 4, respectively. Patients with advanced RV remodelling patterns were more frequently male, had worse renal function, and a higher EuroSCORE II. During a median follow-up of 43 months, 41 adverse events (22 heart failure hospitalisation and 19 deaths) occurred. Patients with patterns 3 and 4 RV remodelling had an increased risk of adverse events compared to pattern 1 (log-rank χ2 27.42; p<0.001; Figure 1). After adjustments for EuroSCORE II and significant tricuspid regurgitation, RV remodelling patterns 3 (Hazard Ratio [HR] 3.24, 95% Confidence Interval [CI] 1.27–8.24, p=0.014) and 4 (HR 6.18, 95% CI 2.49–15.32, p<0.001) were independently associated with poor post-operative outcomes. Importantly, RV remodelling patterns provided incremental prognostic value to EuroSCORE II (χ2 increased from 18 to 38, p<0.001).
Conclusion
In patients with concomitant aortic and mitral valve disease, RV remodelling is frequent and associated with poorer outcomes. Our study highlights the involvement of the RV in left-sided valvular heart disease and underlines the importance of preoperative assessment of RV geometry and function in patients undergoing double valve surgery.

Abstract
Abstract
Background
The burden of myocardial infarction (MI) with its assorted comorbid complications is increasing parallel to rising life expectancy. Careful characterisation of patient characteristics and identification of short- and long-term complications is critical to their management. Nonetheless, data on the evolving profiles of patient features and outcomes, particularly in an Asian population, remain sparse.
Purpose
We aim to describe the evolving characteristics and outcomes of MI patients in Hong Kong in the past 2 decades.
Methods
From a well-validated territory-wide database in Hong Kong, we included patients with incident acute MI from 1999/01/01 to 2018/12/31. The primary outcome was 30-day all-cause death, while secondary outcomes include haemorrhagic stroke, and pneumonia, at both 30 days and 5 years. Temporal trends in baseline characteristics were evaluated using Poisson regression, while trends in outcomes were evaluated using Cox proportional hazard model, adjusted with demographics, comorbidities, and baseline medications.
Results
A total of 130,218 patients (age 73.6±13.9 years, 40.0% female) were included. Over time, while there was no change in the proportion of females (P=0.196), the increase in mean age (APC 0.23% [0.21 to 0.24], P<0.001) was concordant with the increase in mean CCI (APC 5.1%, [4.8 to 5.3], P<0.001), with more patients suffering from baseline comorbidities (Figure 1; range of APC 1.7% to 4.3%; all P<0.001). The proportion of ST elevation increased significantly (APC 2.5% [2.4 to 2.5], P<0.001).
The adjusted all-cause 30-day mortality rate decreased increased significantly (APC 0.3% [0.1 to 0.5], P=0.005). The increasing trend was significant in older patients (≥70 years), non-ST elevation, and female, while there was a decreasing trend mortality rate in ST elevation and young patients; no significant trend was observed in male. Strikingly, there is an alarming increase in the rate of haemorrhagic stroke (APC 3.4% [2.3 to 4.4], P<0.001) and pneumonia (APC 1.5% [1.3 to 1.7], P<0.001) at 30 days (Figure 2). Although the rate of 5-year all-cause death declined slightly (APC −0.8% [−0.9 to −0.6], P<0.001), there were increasing rates of haemorrhagic stroke (APC 1.0% [0.3 to 1.7], P=0.004) and pneumonia (APC 3.8% [3.6 to 4.1], P<0.001). Patients who were older, had ST elevation, and more comorbid were more likely to develop pneumonia.
Conclusions
Patients with MI have evolved to be older and more comorbid. Alarmingly, despite reduction in long-term all-cause death over time, the reduction was small; risk of death in short-term significantly increased and patients suffer from more complications including haemorrhagic stroke and pneumonia. These results highlight the emergence of extra-cardiac outcomes that drive poor prognosis and accentuate the need to develop tailored strategies to tackle these potentially lethal complications.

Abstract
Abstract
Background
The use of fractional flow reserve (FFR) is limited due to the need of invasive pressure wire and hyperaemic stimulus. Computational pressure-flow dynamics derived fractional flow reserve (caFFR) is a novel non-invasive index to determine the FFR in patients with stable coronary artery disease (CAD).
Purpose
The clinical value of caFFR remains uncertain. The aim of the study is to evaluate the prognostic role of caFFR in patients with stable CAD who were treated by optimal medical therapy alone.
Methods
A total of 558 stable CAD patients (mean age=64.5±11.2, 59.0% male) with ≥1 coronary lesion detected during conventional coronary angiogram were included. All of them did not undergo percutaneous coronary intervention and were treated with optimal medical therapy alone. Patients were then classified into 4 groups according to their caFFR value; caFFR ≤0.70 (n=40), caFFR = 0.71–0.80 (n=28), caFFR = 0.81–0.90 (n=292), caFFR = 0.91–1.00 (n=198), with a lower caFFR indicating a greater magnitude of myocardial ischemia. The primary endpoint was 3-year major adverse cardiac events (MACE), defined as a composite of all-cause mortality, myocardial infarction or any unplanned revascularization.
Results
During a median follow-up of 36 months, a total of 49 composite events occurred, including 27 all-cause mortality, 4 myocardial infarction and 18 unplanned revascularization.
After multivariate adjustment, caFFR was an independent predictor of MACE (adjusted hazard ratio [HR] = 0.97 per 0.01 increase in caFFR; 95% confidence interval [Cl], 0.95–0.99; P<0.01), all-cause mortality (adjusted HR = 0.96 per 0.01 increase in caFFR; 95% Cl, 0.94–0.99; P<0.01), and stroke (adjusted HR = 0.95 per 0.01 increase in caFFR; 95% Cl, 0.90–0.99; P=0.03).
The area under the curve (AUC) by receiver-operating characteristic curve analysis (ROC) is 0.70 (95% Cl, 0.62–0.78; P<0.01). The optimal cut-off of caFFR defined by ROC analysis for predicting MACE is 0.80, concluding that patients with caFFR ≤0.80 have significantly higher adverse event rate, which is consistent with the cut-off from wire-based FFR.
Using caFFR = 0.91–1.00 as reference, the risk of MACE was highest in patients with caFFR ≤0.70 (adjusted HR = 4.65; 95% Cl, 1.81–11.94; P<0.01), followed by caFFR = 0.71–0.80 (adjusted HR = 3.67; 95% Cl, 1.12–11.33; P=0.02). The risk of MACE was nonetheless similar among patients with caFFR >0.8 (adjusted HR = 1.39; 95% Cl, 0.61–3.19, P=0.44).
Conclusion
In patients with stable CAD who were treated with optimal medical therapy alone, those with more significant myocardial ischemia, indicated by lower caFFR, had higher risks of adverse outcomes. The finding thus supports the use of this non invasive index to quantify the severity of myocardial ischemia, improve risk-stratification, and predict adverse outcomes in patients with stable CAD.

Abstract
Abstract
Background
Infective endocarditis (IE) is associated with high mortality and complex microbiological profile. The antibiotic prophylaxis guidelines underwent a major revision in 2009 to reduce unnecessary antibiotic exposure. Substantial geographic variations in microbiological profiles exist, of which the understanding in an Asian population is lacking.
Purpose
We aim to describe the trends in the microbiology of IE in Hong Kong in the past 2 decades.
Methods
All patients aged 20 or above diagnosed with incident IE with blood culture results from 2000–2019 were included from a well-validated territory-wide database in Hong Kong, and were classified as 7 groups of causative organisms as shown in Figure 1. To evaluate the association between microbiology and 1-year all-cause death, a multivariable Cox proportional-hazards model was used, adjusted with demographics and comorbidities. Temporal trends in the proportion of each organism were characterised using Poisson regression. Interrupted time series analysis was used to evaluate the change in the organism-specific incidence after the revision of guidelines.
Results
In a total of 5,657 patients (age 59.9±18.3 years, 37.2% females), there were 2,185 (38.6%) patients with culture-negative endocarditis. Staphylococcus aureus (22.4%) and Streptococci (20.5%) were the most common organisms identified.
Over time, there was a significant reduction in the proportion of culture-negative endocarditis (annual percentage change [APC] −2.3% [−2.8 to −1.7], P<0.001), and a significant increase in the proportion of endocarditis due to Staphylococcus aureus (APC 1.6% [0.7 to 2.4], P<0.001) and Streptococci (APC 2.3% [1.4 to 3.3], P<0.001) (Figure 1). After guidelines revision in 2009, there was no significant change in organism-specific incidence (all P-values for relative change>0.05).
Compared to patients with culture-negative endocarditis, those infected with Staphylococcus aureus (hazard ratio [HR] 2.19 [1.94–2.47], P<0.001), other Staphylococci (HR 1.56 [1.20–2.01], P<0.001), Enterococci (HR 1.60 [1.25–2.05], P<0.001), other microorganisms (HR 1.30 [1.05–1.60], P=0.015), and mixed microorganisms (HR 2.40 [2.02–2.84], P<0.001) had a higher risk of 1-year all-cause death (Figure 2).
There was a significant increase in the proportion of methicillin-resistant Staphylococcus aureus (MRSA) endocarditis (APC 4.1% [1.9 to 6.3], P<0.001), with no significant interval change after 2009. Patients infected with MRSA had a higher all-cause death (HR 2.00 [1.70–2.36], P<0.001).
Conclusions
Different causative organisms carry variable mortality signals in infective endocarditis. Over time, there were fewer cases of culture-negative endocarditis, and the revision of antibiotic prophylaxis guidelines did not result in a significant change in the microbiological profile. There was an increasing trend for MRSA endocarditis, which was associated with a higher risk of death.

Abstract
Abstract
Background/Introduction
Despite improvements in diagnostic and therapeutic strategies, the mortality and morbidity of infective endocarditis (IE) remain high. The incidence, outcomes, and surgical intervention of IE, particularly in an Asian population, are poorly understood and characterised, and the effect of antibiotic prophylaxis guidelines revision on the incidence of IE remains unexplored.
Purpose
We aim to describe temporal changes in the epidemiology and surgical intervention for IE in Hong Kong in the past 2 decades.
Methods
From a well-validated territory-wide database in Hong Kong, all patients aged 20 or above diagnosed with incident IE from 2000–2019 were included. The temporal trends in the incidence of IE, rate of surgical intervention, and mean Charlson Comorbidity Index (CCI) were characterised using Poisson regression analysis and expressed in annual percentage change (APC [95% CI]). Interrupted time series analysis was used to evaluate the change in incidence after the revision of antibiotic prophylaxis guidelines. The association between surgical intervention and mortality was evaluated using propensity score analytics. Temporal trends in 1-year all-cause mortality were evaluated using multivariable Cox regression.
Results
A total of 5,657 patients (59.9±18.3 years, 37.2% females) were included. The crude incidence remained was stable from 2000 to 2019 (APC 0.1% [−0.5 to 0.7], P=0.675), and remained unchanged following the revision of antibiotic prophylaxis guidelines in 2008 (relative risk of change 0.90 [0.64 to 1.00], P=0.065) (Figure 1). Concordant with an increase in the mean age of IE patients (APC 0.9% [0.8 to 1.1], P<0.001), the comorbidity burden grew substantially from 2000 (CCI 0.55±1.27) to 2019 (CCI 1.09±1.66).
The rate of surgical intervention significantly increased from 5.3% in 2000 to 17.8% in 2019 (APC 2.7% [1.1 to 4.3], P=0.004), and surgical intervention at 1 year was associated with a 45% risk reduction in 1-year all-cause mortality (Hazard Ratio 0.55 [0.46 to 0.65], P<0.001). Nevertheless, the crude all-cause mortality rate at 1 year increased from 27.4% in 2000 to 31.5% in 2019, with no significant trend after adjustment for demographics and comorbidities (APC −0.7% [−1.6 to 0.1], P=0.087).
Conclusions
In this large cohort of Asian patients, the incidence of IE remained static and did not change following the revision of antibiotic prophylaxis guidelines. Over time, patients with IE have evolved to be older and more comorbid. Despite an increasing rate of surgical intervention that conferred improved survival, the mortality of IE remained irresistibly high.

Abstract
Abstract
Background
Hepatorenal dysfunction and malnutrition are frequent extracardiac consequences of valvular heart disease (VHD) and have emerged as prominent drivers of adverse prognosis in selected valvular interventions. Nonetheless, data in a general VHD population is sparse, and their interaction and changes following valvular surgery remain unexplored.
Purpose
We aim to characterise the temporal changes, interaction, and prognostic implications of hepatorenal dysfunction and malnutrition before and after valvular surgery.
Methods
Baseline and temporal changes in hepatorenal dysfunction (assessed by the modified model for end-stage liver disease [MELD-XI] score) and nutritional status (assessed by Controlling Nutritional Status [CONUT] score) were correlated with adverse events (composite of all-cause mortality and hospitalisation for heart failure) using Cox proportional hazards model, adjusted with clinical and echocardiographic covariates, medications, type of valvular procedure, and cardiac surgery risk-stratification models (EuroSCORE II and STS score).
Results
Our study included 909 patients who underwent valvular surgery. At baseline, 216 (24%) and 554 (61%) had hepatorenal dysfunction (MELD-XI >12.43) and malnutrition (CONUT ≥2), respectively. MELD-XI scores were modestly correlated with CONUT scores (R=0.36, p<0.001), with concomitant hepatorenal dysfunction and malnutrition present in 177 (19%) patients.
Over a median follow-up of 4.1 years, 101 (11%) patients died and 119 (13%) were hospitalised for heart failure. There was a stepwise increase in mortality (χ2 89.1, p<0.001) and adverse events (χ2 92.9, p<0.001) from patients with normal hepatorenal function and nutrition to concomitant hepatorenal dysfunction and malnutrition (Figure 1). This association remained consistent in fully adjusted models. MELD-XI and CONUT scores significantly improved the discriminatory accuracy of EuroSCORE II (area under the curve [AUC]: 0.80 vs 0.73, p<0.001) and STS score (AUC: 0.79 vs 0.72, p=0.004) for all-cause mortality.
In patients with MELD-XI and CONUT scores 1 year after surgery (n=707), ΔMELD-XI (follow-up MELD-XI minus baseline MELD-XI score) and ΔCONUT scores were significantly associated with adverse events (HR 1.08, 95% CI 1.03–1.14, p=0.001 for ΔMELD-XI; HR 1.18, 95% CI 1.02–1.35, p=0.02 for ΔCONUT). Patients remaining with hepatorenal dysfunction and malnutrition experienced worse survival (log-rank χ2 65.2, p<0.001) and adverse events (log-rank χ2 90.4, p<0.001) (Figure 2).
Conclusions
In patients undergoing valvular surgery, hepatorenal function and nutritional status at baseline, and their temporal changes, are strongly linked to clinical outcomes. These results highlight the role of hepatorenal and nutritional assessment for risk-stratification in valvular surgery.

Abstract
Abstract
Introduction
Despite class IA guideline recommendations, the use of fractional flow reserve (FFR) in guiding percutaneous coronary intervention (PCI) in stable coronary artery disease (CAD) patients remains low due to limitations including the need of guidewire placement and hyperaemic stimulus. A novel non-invasive index, computational pressure-flow dynamics derived FFR (caFFR), was developed for measuring functional myocardial ischemia and overcoming the limitations of FFR. However, the clinical relevance of caFFR remains to be investigated. In the present study, we aim at evaluating the prognostic value of caFFR among stable CAD patients.
Methods
We retrospectively included patients with stable CAD who underwent coronary angiography during 2014–2016 at our center. Based on the caFFR value, patients were considered to be ischemic (caFFR ≤0.8) and non-ischemic (caFFR >0.8). Further, we recombined the patients to form the adherence cohort, where patients were defined as adherent-to-caFFR if they were ischemic with PCI or non-ischemic without PCI, and nonadherent-to-caFFR if they were ischemic without PCI or non-ischemic with PCI. The primary endpoint was major adverse cardiac events (MACE), defined as a composite of all-cause mortality, non-fatal myocardial infarction, and any revascularization. Inverse probability of treatment weighting was used to account for treatment selection bias (PCI vs without PCI, or adherent vs non-adherent), and Cox proportional hazard model was used to evaluate the association with MACE.
Results
A total of 1322 patients, 782 patients in the ischemic cohort and 540 patients in the non-ischemic cohort respectively, were included in our analysis. PCI was associated with a lower risk of MACE in the ischemic cohort (hazard ratio [HR] 0.52; 95% confidence interval [CI], 0.34–0.80; P=0.002), but was not associated with MACE in the non-ischemic cohort. In the adherence cohort, adherent-to-caFFR group (n=803) had a lower risk of MACE compared with nonadherent-to-caFFR group (n=566) (HR, 0.61; 95% CI, 0.44–0.85; P=0.003).
Conclusion
Our study is the first to demonstrate the prognostic value of caFFR, a non-wire based assessment of myocardial ischemia, in patients with stable CAD undergoing PCI. These findings support the use of caFFR that bears the potential of a wider adoption compared with wire-based FFR through a reduction in procedure time, risk and costs.

Abstract
Abstract
Background
Surgery is often indicated in patients with infective endocarditis (IE), but the survival benefits of surgical intervention have not been validated in large-scale studies. Although previous studies appeared to support early surgical intervention, the optimal timing of intervention remains uncertain.
Purpose
We aim to evaluate the benefits of surgery and identify the optimal timing of surgical intervention for patients with IE.
Methods
From a well-validated territory-wide database in Hong Kong, all patients aged 20 or above diagnosed with incident IE from 2000–2019 were included. Patients were divided into those who received surgical intervention within 1 year of IE (surgical cohort) and those who did not (control cohort). The two cohorts were then compared using inverse probability weighting of the covariate balancing propensity score, which included demographics, comorbidities, and causative organism as covariates. Outcomes of interest include, at 1 year, all-cause death, and the development of complications. A Cox proportional hazards model was used to evaluate the association between surgical intervention and death, with “doubly-robust estimation” used to minimise the effect of confounders. For complications, a Fine-Gray model was used to account for competing risk.
The surgical cohort was subdivided into early (≤7 days of hospitalisation) or late surgical intervention; a similar propensity score analytic approach was used to evaluate the effects of early vs. late intervention, with those who died within the 7 days excluded to ensure a fair comparison.
Results
A total of 5,657 patients (age 59.9±18.3 years, 37.2% females) were included, of which 930 (16.4%) received surgical intervention in 1 year. Overall, the surgical cohort had a 45% risk reduction in all-cause death (hazard ratio [HR] 0.55, 95% CI [0.46 to 0.65], P<0.001) (Figure). This association remained consistent in subgroup analysis stratified by age, sex, and causative organisms (Table 1).
The surgical cohort also had a lower risk of complications, including acute kidney injury (HR 0.61, 95% CI 0.43 to 0.87, P=0.006), systemic embolism (HR 0.35 [0.23 to 0.55], P<0.001), ischaemic stroke (HR 0.37 [0.24 to 0.55], P<0.001), cardiac dysrhythmia (HR 0.79 [0.66 to 0.95], P=0.011), and pneumonia (HR 0.36 [0.26 to 0.49], P<0.001).
In the surgical cohort, compared to those who had early surgery (N=181), those with delayed surgery had a lower risk of all-cause death (HR 0.58 [0.34 to 0.99], P=0.045) (Figure) and complications (Table 2) at 1 year. In those who had early surgery, patients who received ultra-early surgery (≤3 days of hospitalisation, N=104) did not have a significantly different risk of death (HR 1.19 [0.47 to 3.34], P=0.654).
Conclusions
Surgical intervention significantly reduced the risk of death and complications in patients with infective endocarditis. Delayed surgical intervention appeared to be more protective.

Abstract
Abstract
Background
There are considerable sex differences in patients with myocardial infarction (MI). However, the recent temporal trends in characteristics and outcomes in women vs. men, particularly in an Asian population, remain poorly understood.
Purpose
We aim to evaluate the sex differences in characteristics and outcomes, and how have these differences evolved over the past 2 decades in patients with MI.
Methods
From a well-validated territory-wide database in Hong Kong, we included patients with incident acute MI from 1999/01/01 to 2018/12/31. Outcomes of interest include, at 30 days, all-cause death, new-onset heart failure (HF), and ischaemic stroke. Trends in sex differences in baseline characteristics were evaluated using linear and Poisson regression, while differences in outcomes were evaluated using Cox proportional hazard model, adjusted with demographics, comorbidities, and baseline medications. A Fine-Gray model was used to evaluate HF and ischaemic stroke to account for competing risk, with all-cause death defined as competing event.
Results
A total of 130,218 patients (age 73.6±13.9 years, 40.0% female) were included. Women were older (79.5±11.7 vs. 69.6±13.8 years, P<0.001) and had a more pronounced increasing trend in age over time (interaction P<0.001). Women were also more comorbid overall (Charlson Comorbidity Index [CCI] 1.25 vs 0.85, age-adjusted P<0.001), but the rising trend in CCI over time was less pronounced than in men (interaction P<0.001) (Figure 1). Women had more baseline hypertension, diabetes, and severe renal disease than men (age-adjusted P<0.001), while the increasing trends in these comorbidities were all more pronounced in men than in women (all interaction P<0.001). Women were more likely to have ST-elevation overall (P<0.001).
Although the crude 30-day mortality rate was higher in women (32.6% vs 23.9%), after adjustment for confounders, they had a lower risk of death (hazard ratio [HR] 0.97, 95% CI [0.96 to 0.99], P=0.003). There was no significant difference in the decreasing trend in 30-day mortality between both sexes (interaction P=0.787) (Figure 1). Women had a higher risk of developing HF (HR 1.04 [1.01 to 1.08], P=0.012) and ischemic stroke (HR 1.36 [1.24 to 1.48], P<0.001) in 30 days.
Among patients aged ≤55 (N=15,324), women (N=2,161, 14.1%) had higher risks of all-cause death (HR 1.61 [1.40 to 1.85], P<0.001), HF (HR 1.64 [1.17 to 2.32], P=0.004), and ischemic stroke (HR 1.69 [1.14 to 2.51], P=0.010) in 30 days, even after adjustment for covariates. The excess mortality in women declined over time (interaction P=0.002).
Conclusions
Women MI patients were older and more comorbid compared to men, which contributed to the higher risk of death, HF, and ischemic stroke among women. Among young MI patients, the increased risk for adverse outcomes among women was particularly pronounced, though the sex differences in mortality reduced over time.

Abstract
Abstract
Background
Computational pressure-flow dynamics derived fractional flow reserve (caFFR) is a novel index developed to evaluate the extent of myocardial ischemia in patients with coronary artery disease (CAD), which eliminates the need of invasive pressure guidewire and hyperaemic stimulus in conventional fractional flow reserve (FFR) measurement. Studies have shown improved clinical outcomes associated with adherence to functional myocardial ischemia assessment when deciding to perform percutaneous coronary intervention (PCI) at a per-patient level. However, the clinical significance of such treatment adherence at a per-vessel level remains uncertain.
Methods
A total of 928 patients (mean age 66.2±10.5, male 72.7%) with stable CAD were included in this study. The caFFR of all three major coronary vessels were obtained for every patient, and the FFR threshold of 0.8 was adopted as the threshold for caFFR to indicate functionally significant artery stenosis which warrants PCI, and vice versa. Based on the caFFR of each major coronary vessel and whether PCI was performed to the respective vessel, patients were stratified into 0–1 vessel with treatment adherence group (group 1) (n=105), 2 vessels with treatment adherence group (group 2) (n=338), and 3 vessels with treatment adherence group (group 3) (n=485). The primary endpoint was major adverse cardiac events (MACE), defined as a composite of all-cause mortality, non-fatal myocardial infarction and any subsequent revascularization.
Results
The severity of CAD based on SYNTAX score assessment was 18.6±10.2 in group 1, 14.6±8.9 in group 2, and 11.5±9.9 in group 3 (P<0.001). The rates of MACE at 3 years were significantly different across groups 1, 2 and 3 (17.1% vs. 12.1% vs. 7.4%; P=0.004). With reference to group 3, the risk of MACE at 3 years was increased in group 2 (adjusted hazard ratio [HR]=1.597; 95% confidence interval [CI]=1.020–2.501; P=0.041), and further increased in group 1 (adjusted HR=1.933; 95% CI=1.081–3.457; P=0.026).
Conclusion
In stable CAD patients, the risk of MACE is incremental when fewer major coronary vessels are treated with adherence to caFFR threshold of 0.8. Per-vessel treatment adherence significantly affects clinical outcomes in terms of MACE.

Abstract
Abstract
Background
A substantial proportion of patients with acute coronary syndrome (ACS) may have intermediate lesion that are non-ischemic during emergency coronary angiography. The prognosis of such patients, compared to those with stable ischemic heart disease (SIHD) without ischemic lesion is however uncertain. Recently, a novel index, computational pressure-flow dynamics derived fractional flow reserve (caFFR), has been developed to assess myocardial ischemia, without the need of invasive pressure wire and hyperaemic stimulus as required in conventional fractional flow reserve (FFR). By utilizing caFFR to assess for ischaemic status during coronary angiography, the aim of our study is first to assess the prognostic difference between ACS and SIHD with non-ischaemia intermediate lesions. Second, we ascertain whether PCI in patients with ACS with non-ischaemia intermediate lesions provides survival benefit in addition to medical therapy.
Methods
We retrospectively recruited 551 patients (mean age 64.4 years; male 59.9%) with absence of myocardial ischaemia, defined as caFFR ≥0.80 in all vessels, from our Hospital. Patients were stratified into those with index presentation of ACS (n=132) and those with SIHD (n=491). Among the ACS cohort, patients were further divided into those with PCI (n=83) and with medical therapy alone (n=49). The SIHD cohort (n=491), all of whom were treated with medical therapy alone, was considered as referent group. The primary end point was major adverse cardiovascular events (MACE) at 3 years, which was defined as a composite of all-cause mortality, non-fatal myocardial infarction (MI), and any unplanned revascularization.
Results
During a median follow-up of 36 months, 54 composite events occurred, including 38 all-cause mortality, 5 MI, and 14 unplanned revascularization. Compared to those with SIHD, patients with ACS was independently associated with MACE even in the absence of myocardial ischaemia (adjusted Hazard Ratios=2.531; 95% confidence interval=1.397–4.586; P=0.002). The 3-year incidence rate of MACE was the highest in ACS patients with medical therapy alone, followed by ACS patients with immediate PCI; the SIHD cohort had the lowest incidence rates (30.6% vs 12.0% vs 5.9%, P<0.001). This was mainly driven by the rate of all-cause death (26.5% vs 12.0% vs 3.1%; P<0.001). Similar findings were observed for hospitalisation due to heart failure (14.3% vs 6.0% vs 3.1%, P=0.031) and cardiac death (8.2% vs 4.8% vs 0.4%, P<0.001) at 3 years.
Conclusion
In patients with intermediate lesion without myocardial ischaemia (defined as caFFR ≥0.8), those presented with ACS had a higher risk of MACE at 3 years compared to SIHD. Among ACS patients with intermediate lesion without myocardial ischaemia, PCI significantly reduces the rate of MACE. In patients with ACS, our finding suggests that PCI should be advocated to intermediate lesion even without myocardial ischaemia.

Abstract
BACKGROUND AND AIMS Increased serum uric acid (SUA) is common in type 2 diabetes mellitus (T2DM) and is associated with left ventricular (LV) myocardial dysfunction. Nonetheless the association of SUA with right ventricular (RV) function in T2DM has not been studied. This study aimed to investigate the association of SUA with biventricular myocardial function in patients with T2DM. METHODS AND RESULTS A total of 560 patients with T2DM were enrolled and divided into four groups according to sex-specific quartiles of SUA. Transthoracic echocardiography was performed and two-dimensional speckle tracking was used to measure biventricular myocardial strain, including LV global longitudinal strain (GLS), circumferential strain (CS), radial strain (RS), and RV free wall longitudinal strain (RV-FWLS). The absolute value of all biventricular strain parameters showed a stepwise decrease across SUA quartiles (all P < 0.01). In particular, LV assessment by GLS, CS and RS demonstrated that those in the 4th quartile were impaired compared with the other quartiles (all P < 0.05). Similarly, RV-FWLS of the 4th quartile was significantly impaired compared with the 1st and 2nd quartiles (all P < 0.05). The same reduction in biventricular strain across SUA quartiles was observed in patients with estimated glomerular filtration rate < or ≥60 ml/min/1.73 m2, and glycated hemoglobin < or ≥7.0% (all P < 0.05). Multivariable linear regression analysis demonstrated that higher quartile of SUA was independently associated with impaired biventricular myocardial strain (all P < 0.05). CONCLUSIONS SUA was independently associated with biventricular myocardial dysfunction in asymptomatic T2DM patients, regardless of renal function or diabetic control.

Abstract
AIMS Few prospective studies have evaluated sex-specific pattern, natural progression of left ventricular (LV) remodelling, and diastolic dysfunction in patients with type 2 diabetes (T2DM). The aim of this study was to study the sex-specific prevalence, longitudinal changes of LV remodelling, and diastolic dysfunction in patients with T2DM. Further, the prognostic value of diastolic function in women and men was also evaluated. METHODS AND RESULTS A total of 350 patients with T2DM (mean age 61 ± 11 years; women, 48.3%) was recruited. Detailed echocardiography was performed at baseline and after 25 months. A major adverse cardiovascular event (MACE) was defined as cardiovascular death, heart failure hospitalization, or myocardial infarction. Despite a similar age, prevalence of hypertension and body mass index, women had a higher prevalence of LV hypertrophy and diastolic dysfunction at baseline and follow-up compared with men. A total of 21 patients developed MACE (5 cardiovascular death, 9 hospitalization for heart failure, and 7 myocardial infarction) during a median follow-up of 56 months. Women with diastolic dysfunction had a higher incidence of MACE than those with normal diastolic function but this association was neutral in men. Multivariable Cox-regression analysis indicated that diastolic dysfunction was associated with MACE in women [hazard ratio = 6.30; 95% confidence interval (CI) = 1.06-37.54; P < 0.05] but not men (hazard ratio = 2.29, 95% CI = 0.67-7.89; P = 0.19). CONCLUSION LV hypertrophy and diastolic dysfunction, both at baseline and follow-up, were more common in women than men. Pre-clinical diastolic dysfunction was independently associated with MACE only in women with T2DM but was neutral in men.

Abstract
Aims Patients with heart failure (HF) have an increased risk of incident cancer. Data relating to the association of statin use with cancer risk and cancer-related mortality among patients with HF are sparse. Methods and results Using a previously validated territory-wide clinical information registry, statin use was ascertained among all eligible patients with HF (n = 87 102) from 2003 to 2015. Inverse probability of treatment weighting was used to balance baseline covariates between statin nonusers (n = 50 926) with statin users (n = 36 176). Competing risk regression with Cox proportional-hazard models was performed to estimate the risk of cancer and cancer-related mortality associated with statin use. Of all eligible subjects, the mean age was 76.5 ± 12.8 years, and 47.8% was male. Over a median follow-up of 4.1 years (interquartile range: 1.6–6.8), 11 052 (12.7%) were diagnosed with cancer. Statin use (vs. none) was associated with a 16% lower risk of cancer incidence [multivariable adjusted subdistribution hazard ratio (SHR) = 0.84; 95% confidence interval (CI), 0.80–0.89]. This inverse association with risk of cancer was duration dependent; as compared with short-term statin use (3 months to <2 years), the adjusted SHR was 0.99 (95% CI, 0.87–1.13) for 2 to <4 years of use, 0.82 (95% CI, 0.70–0.97) for 4 to <6 years of use, and 0.78 (95% CI, 0.65–0.93) for ≥6 years of use. Ten-year cancer-related mortality was 3.8% among statin users and 5.2% among nonusers (absolute risk difference, −1.4 percentage points [95% CI, −1.6% to −1.2%]; adjusted SHR = 0.74; 95% CI, 0.67–0.81). Conclusion Our study suggests that statin use is associated with a significantly lower risk of incident cancer and cancer-related mortality in HF, an association that appears to be duration dependent.

Abstract
Background Cardiac arrhythmias are associated with poorer outcomes in patients with heart failure (HF), diabetes mellitus (DM), and chronic kidney disease (CKD). Previous studies have shown inconsistent conclusions regarding the association between sodium-glucose cotransporter 2 inhibitors (SGLT2i) and the risk of developing arrhythmias. This study aims to investigate the association of SGLT2i treatment with arrhythmia outcomes in clinical trials of patients with HF, DM, or CKD. Methods MEDLINE, EMBASE, and ClinicalTrials.gov were searched from inception up to 27 August 2020. Randomized controlled trials that randomized patients with DM, CKD, or HF to SGLT2i or placebo were included. The outcomes of interest include atrial fibrillation (AF), embolic stroke, atrial flutter (AFL), AF/AFL, ventricular tachycardia (VT), and cardiac arrest. Relative risks (RRs) and 95% confidence intervals (CI) were pooled using a random-effects model. Results Out of 4,532 citations, 22 trials with altogether 52,115 patients were included (mean age 63.2 years; 33,747 [64.8%] of participants were men). SGLT2i were associated with a lower risk of AF (RR 0.82, 95% CI 0.70–0.96), embolic stroke (RR 0.32, 95% CI 0.12–0.85), AF/AFL (RR 0.82, 95% CI 0.71–0.95), and VT (RR 0.73, 95% CI 0.53–0.99), while the risk reductions in AFL (RR 0.83, 95% CI 0.58–1.17) and cardiac arrest (RR 0.83, 95% CI 0.61–1.14) did not reach statistical significance. The associations appeared to be consistent across different baseline conditions (DM vs CKD vs HF; atherosclerotic cardiovascular disease [ASCVD] vs no ASCVD) and the SGLT2i used. Conclusions SGLT2i reduced the risk of cardiac arrhythmias. Our study provides further evidence for recommending the use of SGLT2i in patients with DM, CKD, and HF. Further research is needed to fully elucidate the mechanism by which SGLT2i protect against arrhythmias.

Abstract
BACKGROUND Liver stiffness (LS) assessed by transient elastography is associated with adverse events in patients with heart failure. However, the predictive value of LS for adverse outcome is uncertain in patients undergoing tricuspid annuloplasty (TA). This study sought to evaluate the prognostic value and reversibility of LS in patients undergoing TA during left-sided valve surgery. METHODS AND RESULTS A total of 158 patients who underwent TA were prospectively evaluated. Patients were divided into three groups according to tertile of LS. Adverse outcome was defined as heart failure that required hospital admission or all-cause mortality following TA. The median LS was 13.9 (inter-quartile range 8.1-22.3) kPa and independently correlated positively with tricuspid regurgitation (TR) severity, inferior vena cava diameter and negatively with tricuspid annular plane systolic excursion. During a median follow-up of 31 months, 49 adverse events occurred. Multivariable Cox regression analysis revealed that LS was an independent predictor of adverse events. Significant improvement in LS at 1-year post-TA (13.1-7.8 kPa, P < 0.01) was noted only in patients who had no adverse events, not in those who experienced heart failure (17.1-14.2 kPa, P = 0.87) and seems to be linked to an absence of TR recurrence. CONCLUSIONS This study demonstrated that LS is predictive of adverse outcome and is reversible in patients undergoing TA without TR recurrence at 1 year. These findings suggest that assessing LS, an integrative correlate of right heart condition, may aid the pre-operative risk assessment of candidate for heart surgery including TA.

Abstract
Background The relationship between adipocyte fatty acid-binding protein (AFABP) and cardiac remodelling has been reported in cross-sectional studies, although with conflicting results. Type 2 diabetes mellitus (T2DM) is associated with left ventricular (LV) hypertrophy and diastolic dysfunction, as well as elevated circulating AFABP levels. Here we investigated prospectively the association between AFABP with the longitudinal changes of cardiac remodelling and diastolic dysfunction in T2DM. Methods Circulating AFABP levels were measured in 176 T2DM patients without cardiovascular diseases (CVD) at baseline. All participants received detailed transthoracic echocardiography both at baseline and after 1 year. Multivariable linear and Cox regression analyses were used to evaluate the associations of circulating AFABP levels with changes in echocardiography parameters and incident major adverse cardiovascular events (MACE), respectively. Results The median duration between baseline and follow-up echocardiography assessments was 28 months. Higher sex-specific AFABP quartiles at baseline were associated with increase in LV mass and worsening of average E/e′ (all P < 0.01). Multivariable linear regression demonstrated that AFABP in the highest quartile was independently associated with both increase in LV mass (β = 0.89, P < 0.01) and worsening of average E/e′ (β = 0.57, P < 0.05). Moreover, multivariable Cox regression analysis showed that elevated baseline circulating AFABP level independently predicted incident MACE (HR 2.65, 95% CI 1.16–6.05, P < 0.05) after adjustments for age, sex, body mass index, glycated haemoglobin, hypertension, dyslipidemia and presence of chronic kidney disease. Conclusion Circulating AFABP level at baseline predicted the development of LV hypertrophy, diastolic dysfunction and MACE in T2DM patients without CVD.
