Abstract
Background To evaluate whether metformin use assuredly alters overall all-cause death in patients with type 2 diabetes mellitus (T2DM) and chronic kidney disease (CKD). Methods Pubmed, Web of Science, Embase, and Cochrane Central Register of Controlled Trials were systematically searched from inception to Feb. 29, 2020 with no language restriction. All related articles comparing all-cause death of T2DM and CKD patients after metformin use (monotherapy or combination) versus non-metformin treatment were identified. Pooled risk ratios (RR) and 95% confidence intervals (CI) were computed using random-effects models regardless of the heterogeneity quantified by Cochrane χ2 and I2 statistics. Results Totally 13 studies (9 cohort studies [CSs], 3 subanalyses or post-hoc analyses of randomized controlled trials [RCTs], and 1 nested case-control article) involving 303,540 patients were included. Metformin-based treatments relative to any other measure displayed significantly lower risks of all-cause mortality (Pooled RRs 0.71, 95%CI 0.61 to 0.84; I2 = 79.0%) and cardiovascular events (Pooled RRs 0.76, 95%CI 0.60 to 0.97; I2 = 87.0%) in CKD patients at stage G1-3, with substantial heterogeneity. Metformin use was not significantly related with these end points in advanced CKD patients. Conclusions Metformin use is connected with significantly less risks of all-cause mortality and cardiovascular events in patients with T2DM and mild/moderate CKD. However, RCTs with large sample sizes are warranted in the future to assess whether these key benefits extend to later stages of CKD by dose adjustment.

Abstract
BACKGROUND Slopes of eGFR have been associated with increased risks of death and cardiovascular events in a U-shaped fashion. Poor outcomes in individuals with rising eGFR are potentially attributable to sarcopenia, hemodilution, and other indicators of clinical deterioration. METHODS To investigate the association between eGFR slopes and risks of death or cardiovascular events, accounting for multiple confounders, we studied 2738 individuals with moderate to severe CKD participating in the multicenter Chronic Renal Insufficiency Cohort (CRIC) Study. We used linear, mixed-effects models to estimate slopes with up to four annual eGFR assessments, and Cox proportional hazards models to investigate the association between slopes and the risks of death and cardiovascular events. RESULTS Slopes of eGFR had a bell-shaped distribution (mean [SD], -1.5 [-2] ml/min per 1.73 m2 per year). Declines of eGFR that were steeper than the average decline associated with progressively increasing risks of death (hazard ratio [HR], 1.23; 95% confidence interval [95% CI], 1.09 to 1.39; for a slope 1 SD below the average) and cardiovascular events (HR, 1.19; 95% CI, 1.03 to 1.38). Rises of eGFR or declines lower than the average decline were not associated with the risk of death or cardiovascular events. CONCLUSIONS In a cohort of individuals with moderate to severe CKD, we observed steep declines of eGFR were associated with progressively increasing risks of death and cardiovascular events; however, we found no increased risks associated with eGFR improvement. These findings support the potential value of eGFR slopes in clinical assessment of adults with CKD.

Front Physiol 2020; 11:1027. [PMID: 33117185 PMCID: PMC7574772 DOI: 10.3389/fphys.2020.01027] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2020] [Accepted: 07/27/2020] [Indexed: 12/22/2022] Open
Abstract
Objective: Fragmented QRS (fQRS) have been reported as a predictor of major adverse cardiac events (MACE) and mortality in several studies on cardiovascular disease. However, most studies have yielded discrepant results. This study aimed to explore the correlation between fQRS and cardiovascular events in patients with acute myocardial infarction (AMI) during their hospital stay and follow-up period, and the predictive value of fQRS in the prognosis of AMI. Methods: We searched for relevant studies in four databases, Medline, Embase, PubMed, and the Cochrane Library from January 2010 to March 2020. Our initial search yielded 585 articles. Of these, we screened 19 studies, and finally included a total of 6,914 patients in this analysis, comparing death events or MACE in AMI patients with or without fQRS. Results: Fragmented QRS was significantly associated with a higher risk of in-hospital mortality (OR, 3.97; 95% CI, 2.45-6.44; p < 0.00001), long-term mortality (OR, 2.93; 95% CI, 1.76-4.88; p < 0.0001), in-hospital MACE (OR, 2.48; 95% CI, 1.62-3.80; p < 0.0001), and long-term MACE (OR, 3.81; 95% CI, 2.21-6.57; p < 0.00001). In particular, it demonstrated a higher predictive value for in-hospital cardiovascular mortality and long-term all-cause mortality in AMI patients and in-hospital mortality in patients with ST-segment elevation myocardial infarction (STEMI). Moreover, fQRS was also associated with an increased risk of ventricular arrhythmias (OR, 2.76; 95% CI, 1.72-4.43; p < 0.0001) and heart failure (OR, 1.65; 95% CI, 1.02-2.66; p = 0.04). Fragmented QRS was negatively associated with left ventricular ejection function (LVEF) (MD, -5.47; CI, [-7.03, -3.91]; p < 0.00001) and positively associated with a high incidence of coronary artery triple vessel lesions (OR, 2.14; 95% CI, 1.31-3.51; p = 0.002) in AMI patients. Conclusion: Fragmented QRS is significantly associated with in-hospital and long-term mortality and MACE in patients with AMI, as well as ventricular arrhythmias and heart failure. Furthermore, it may be a marker of mortality and MACE risk. Moreover, fQRS also indicates a reduced LVEF and a high incidence of coronary artery triple vessel lesions in AMI patients.

Abstract
Aim: Both apical periodontitis (AP) and metabolic syndrome (MetS) are associated with atherosclerotic cardiovascular disease (ACVD), the main cause of cardiovascular events. The aim of this study was to investigate the prevalence of AP and the oral inflammatory burden in control subjects and patients suffering cardiovascular events, analyzing the possible association between AP and the oral inflammatory burden with MetS. Materials and Methods: Using a cross-sectional design, 83 patients suffering a cardiovascular event were recruited in the study group (SG), and 48 patients without cardiovascular events were included in the control group (CG). Periapical index (PAI) was used to diagnose AP, and total dental index (TDI) was used to assess the total oral inflammatory burden. Diagnosis of MetS was made by meeting three or more American Heart Association Scientific Statement components. Results: In the multivariate logistic regression analysis, the number of teeth with AP (OR = 2.3; 95% C.I. = 1.3–4.3; p = 0.006) and TDI scores (OR = 1.5; 95% C.I. = 1.2–1.9; p = 0.001), significantly correlated with cardiovascular events. MetS was strongly associated (OR = 18.0; 95% C.I. = 6.5–49.7; p = 0000) with cardiovascular events. Higher TDI scores were significantly associated with MetS (OR = 1.3; 95% C.I. = 1.1–1.6; p = 0.003. Neither the number of root-filled teeth (RFT) (OR = 0.9; 95% C.I. = 0.6–1.3; p = 0.61) nor the number of teeth with apical periodontitis (OR = 1.1; 95% C.I. = 0.8–1.7; p = 0.49) were associated with MetS. Conclusions: Apical periodontitis is significantly associated with cardiovascular events. Total oral inflammatory burden assessed by TDI, but not AP alone, is associated with MetS.

Abstract
OBJECTIVE Serum human epididymis protein 4 (HE4) is associated with immune and inflammatory responses. This study aimed to assess the performance of serum HE4 in the early detection of cardiovascular (CV) events in patients with chronic obstructive pulmonary disease (COPD). METHODS Serum HE4 levels were measured in 199 patients with COPD, all of whom were prospectively followed up for a median period of 36 months (range = 3 months-38 months). Logistic regression analysis was performed to assess the association between cardiovascular disease (CVD) history and HE4 in patients with COPD. Cox proportional hazard analysis was performed to assess the prognostic value of serum HE4 for predicting CV events. RESULTS Serum HE4 levels were higher in patients with COPD with CV events than in those without CV events (252.6 pmol/L [186.4-366.8] vs 111.0 pmol/L [84.8-157.1]; P <.001). The multivariate logistic regression model revealed that serum HE4 (odds ratio = 1.639; 95% confidence interval [CI], 1.213-2.317; Ptrend =.009) was independently associated with CVD history after adjusting for age, sex, body mass index, current smoking status, current alcohol consumption status, admission systolic blood pressure and diastolic blood pressure, hyperlipidemia, left ventricular ejection fraction, primary diseases, and laboratory measurements in patients with COPD at baseline. The multivariate Cox proportional hazard analysis revealed that serum HE4 (hazard ratio = 2.012; 95% CI, 1.773-4.469; P <.001) was an independent prognostic factor for CV events in these patients. The Kaplan-Meier analysis showed that the rate of CV events was higher in patients with COPD with HE4 levels above the median (187.5 pmol/L) than in those with HE4 levels below the median. CONCLUSION Our results showed that serum HE4 was significantly and independently associated with CVD history and had independent predictive value for CV events in patients with COPD. Serum HE4 may enable early recognition of CV complication development among patients with COPD.

Abstract
Background Vascular cell adhesion molecule-1 (VCAM-1) is associated with vascular-related inflammation and atherosclerosis. This study aimed to evaluate whether VCAM-1 can be used for an indication of increased risk of CV events in patients with COPD. Methods Serum VCAM-1 levels were measured in 163 COPD patients. All COPD patients were prospectively followed up for a median period of 48 months (range=3-54). Cox proportional hazard analysis was performed to evaluate the prognostic value of serum VCAM-1 for predicting CV events. Results Serum VCAM-1 levels were higher in COPD patients with CV events than in those without CV events (1174.4±365.3 ng/mL vs 947.8±293.2 ng/mL; P<0.001). The logistic regression analysis revealed that serum VCAM-1 (OR=1.750; 95% CI, 1.324-2.428; Ptrend=0.0012) was independently associated with CVD (cardiovascular disease) history after adjusting for age, sex, BMI, current smoker, current drinker, admission systolic and diastolic BP, LVEF and laboratory measurements in patients with COPD at baseline. The Kaplan-Meier analysis demonstrated that the rate of CV events was higher in COPD patients with serum VCAM-1 levels above the median (517.3 ng/mL) than in those with VCAM-1 levels below the median. The Cox proportional hazard analysis revealed that serum VCAM-1 (HR=2.617; 95% CI, 1.673-5.328; Ptrend<0.001) may be an independent prognostic factor for CV events in the COPD patients. Conclusion Our results suggested that serum VCAM-1 was significantly and independently associated with CV events in COPD patients. The inflammatory marker may help clinicians predict CV complications early.

Abstract
Community-acquired pneumonia (CAP) remains an important cause of morbidity and mortality throughout the world with much recent and ongoing research focused on the occurrence of cardiovascular events (CVEs) during the infection, which are associated with adverse short-term and long-term survival. Much of the research directed at unraveling the pathogenesis of these events has been undertaken in the settings of experimental and clinical CAP caused by the dangerous, bacterial respiratory pathogen, Streptococcus pneumoniae (pneumococcus), which remains the most common bacterial cause of CAP. Studies of this type have revealed that although platelets play an important role in host defense against infection, there is also increasing recognition that hyperactivation of these cells contributes to a pro-inflammatory, prothrombotic systemic milieu that contributes to the etiology of CVEs. In the case of the pneumococcus, platelet-driven myocardial damage and dysfunction is exacerbated by the direct cardiotoxic actions of pneumolysin, a major pore-forming toxin of this pathogen, which also acts as potent activator of platelets. This review is focused on the role of platelets in host defense against infection, including pneumococcal infection in particular, and reviews the current literature describing the potential mechanisms by which platelet activation contributes to cardiovascular complications in CAP. This is preceded by an evaluation of the burden of pneumococcal infection in CAP, the clinical features and putative pathogenic mechanisms of the CVE, and concludes with an evaluation of the potential utility of the anti-platelet activity of macrolides and various adjunctive therapies.

Abstract
The role of aspirin for primary prevention in older adults with chronic kidney disease (CKD) is unclear. Therefore, post hoc analysis of the randomized controlled trial ASPirin in Reducing Events in the Elderly (ASPREE) was undertaken comparing 100 mg of enteric-coated aspirin daily against matching placebo. Participants were community dwelling adults aged 70 years and older in Australia, 65 years and older in the United States, all free of a history of dementia or cardiovascular disease and of any disease expected to lead to death within five years. CKD was defined as present at baseline if either eGFR under 60mL/min/1.73m2 or urine albumin to creatinine ratio 3 mg/mmol or more. In 4758 participants with and 13004 without CKD, the rates of a composite endpoint (dementia, persistent physical disability or death), major adverse cardiovascular events and clinically significant bleeding in the CKD participants were almost double those without CKD. Aspirin's effects as estimated by hazard ratios were generally similar between CKD and non-CKD groups for dementia, persistent physical disability or death, major adverse cardiovascular events and clinically significant bleeding. Thus, in our analysis aspirin did not improve outcomes in older people while increasing the risk of bleeding, with mostly consistent effects in participants with and without CKD.

Abstract
Background Sclerostin and Dickkopf-related protein-1 (Dkk-1) proteins are inhibitors of the canonical Wnt/β-catenin bone pathway. Sclerostin but not Dkk-1 is associated with increased arterial stiffness. This study examined the prognostic significance of sclerostin and Dkk-1 levels for cardiovascular outcomes and mortality in haemodialysis (HD) patients. Methods Serum sclerostin and Dkk-1 levels were measured with enzyme-linked immunosorbent assay in 80 HD patients that were followed-up for a median of 45 months. Factors that could interfere with the association of sclerostin and Dkk-1 with outcomes [including carotid–femoral pulse wave velocity (PWV), parathyroid hormone (PTH), calcium–phosphate product and others] were assessed at baseline. The primary endpoint was a combination of all-cause death, non-fatal myocardial infarction, non-fatal stroke, coronary revascularization, hospitalization for decompensated heart failure and new-onset atrial fibrillation. Secondary endpoints included cardiovascular and all-cause mortality. Results Cumulative freedom from the primary endpoint was significantly lower for higher tertiles of sclerostin (77.8, 69.2 and 40.7%; Tertiles 1–3, respectively; log-rank P = 0.004). The risk for the primary outcome gradually increased for higher sclerostin tertiles [Tertile 3: hazard ratio (HR) = 3.847, 95% confidence interval (CI) 1.502–9.851]. No significant association was evident between sclerostin and all-cause mortality, whereas higher sclerostin levels presented a trend towards higher risk for cardiovascular mortality. Dkk-1 levels exhibited no association with the risk of the primary or secondary endpoints. In stepwise Cox regression modelled analysis, sclerostin levels were associated with the primary outcome, independently of PTH, calcium–phosphate product, serum albumin, C-reactive protein and PWV levels (HR = 2.921, 95% CI 1.401–6.090; P = 0.004). Conclusions High sclerostin levels are associated with lower cumulative freedom and higher risk for a composite endpoint of cardiovascular events and mortality. Dkk-1 exhibited no association with the future risk of adverse outcomes.

Abstract
Background The long‐term prognosis of refractory hypertension (RfHT), defined as failure to control blood pressure (BP) levels despite an antihypertensive treatment with ≥5 medications including a diuretic and mineraloreceptor antagonist, has never been evaluated. Methods and Results In a prospective cohort study with 1576 patients with resistant hypertension, patients were classified as refractory or nonrefractory based on uncontrolled clinic (or office) and ambulatory BPs during the first 2 years of follow‐up. Multivariate Cox analyses examined the associations between the diagnosis of RfHT and the occurrence of total cardiovascular events (CVEs), major adverse CVEs, and cardiovascular and all‐cause mortality, after adjustments for other risk factors. In total, 135 patients (8.6%) had RfHT by uncontrolled ambulatory BPs and 167 (10.6%) by uncontrolled clinic BPs. Over a median Follow‐Up of 8.9 years, 338 total CVEs occurred (288 major adverse CVEs, including 124 myocardial infarctions, and 96 strokes), and 331 patients died, 196 from cardiovascular causes. The diagnosis of RfHT, using either classification by clinic or ambulatory BPs, was associated with significantly higher risks of major adverse CVEs, cardiovascular mortality, and stroke incidence, with hazard ratios varying from 1.54 to 2.14 in relation to patients with resistant nonrefractory hypertension; however, the classification based on ambulatory BPs was better in identifying higher risk patients than the classification based on clinic BP levels. Conclusions Patients with RfHT, particularly when defined by uncontrolled ambulatory BP levels, had higher risks of major adverse CVEs and mortality in relation to patients with resistant but nonrefractory hypertension, supporting the concept of refractory hypertension as a true extreme phenotype of antihypertensive treatment failure.

Abstract
Cardiovascular disease (CVD) is the leading cause of death worldwide and one key factor associated with the increased CVD risk is dyslipidemia. Statin therapy remains the first-line treatment to manage dyslipidemia, yet many patients do not achieve optimal low-density lipoprotein-cholesterol (LDL-C) levels even after taking moderate- or high-intensity statins; therefore, additional, non-statin therapy is often needed. Bempedoic acid is a prodrug that, once activated, decreases LDL-C levels by the inhibition of adenosine triphosphate citrate lyase in the liver. Five clinical trials have demonstrated the safety and efficacy of bempedoic acid and the bempedoic acid/ezetimibe combination in lowering LDL-C in patients with atherosclerotic CVD and heterozygous familial hypercholesterolemia and also in high-risk primary prevention, and statin-intolerant patients. Bempedoic acid has been demonstrated to lower LDL-C levels by 15-25% in clinical trials and up to 38% when combined with ezetimibe. In 2020, the FDA approved bempedoic acid. Furthermore, the combination of bempedoic acid with ezetimibe is FDA approved for the treatment of adults with heterozygous familial hypercholesterolemia or established atherosclerotic CVD who require additional LDL-C lowering after maximally tolerated statin therapy. The ongoing CLEAR OUTCOMES trial aims to evaluate whether bempedoic acid can reduce cardiovascular events in patients with statin intolerance and results will be available in the next 3 years. This outcomes trial will be pivotal for determining the role of bempedoic acid in the non-statin lipid-lowering armamentarium.

Abstract
Background Epidemiological studies have reported discrepant findings on the relationship between education level and outcomes after stroke. We aimed to prospectively investigate the relationship between education level and mortality, recurrent stroke, and cardiovascular events in Chinese patients with ischemic stroke. Methods and Results We included 3861 participants from the China Antihypertensive Trial in Acute Ischemic Stroke. Education level was categorized as illiteracy, primary school, middle school, and college. Study outcomes were all‐cause mortality, stroke‐specific mortality, recurrent stroke, and cardiovascular events within 2 years after ischemic stroke. A meta‐analysis was conducted to incorporate the results of the current study and previous other studies on the association of education level with outcomes after stroke. Within 2 years after ischemic stroke, there were 327 (8.5%) all‐cause deaths, 264 (6.8%) stroke‐specific deaths, 303 (7.9%) recurrent strokes, and 364 (9.4%) cardiovascular events, respectively. The Kaplan–Meier curves showed that patients with the lowest education level had the highest cumulative incidence rates of all‐cause mortality, stroke‐specific mortality, and cardiovascular events (log‐rank P≤0.01). After adjusted for covariates, hazard ratios and 95% CIs of illiteracy versus college education were 2.79 (1.32–5.87) for all‐cause mortality, 3.68 (1.51–8.98) for stroke‐specific mortality, 2.82 (1.20–6.60) for recurrent stroke, and 3.46 (1.50–7.95) for cardiovascular events. The meta‐analysis confirmed the significant association between education status and mortality after stroke (pooled relative risk for lowest versus highest education level, 1.24 [95% CI, 1.05–1.46]). Conclusions Low education level was significantly associated with increased risk of mortality, recurrent stroke, and cardiovascular events after ischemic stroke, independently of established risk factors.

Abstract
PURPOSE It is unclear whether plasma homocysteine (Hcy) has a direct noxious impact on the cardiovascular (CV) system or whether its association with cardiovascular events (CVEs) is mediated by established risk factors. To explore the role of Hcy in CV impairment, the study evaluated cross-sectional relationships between plasma Hcy and indices of CV organ damage together with the associations of these indices with the history of CVEs. METHODS In 269 patients with a high prevalence of diabetes, dyslipidemia, and hypertension, the carotid intima-media thickness, ankle-brachial index (ABI), reactive hyperemic index, carotid-femoral pulse wave velocity (cfPWV), left ventricular (LV) mass, and cardiac index were measured. RESULTS 132 patients had carotid plaque, 31 ABI < 0.90, 126 endothelial dysfunction, 66 increased cfPWV, 125 LV hypertrophy (LVH), 153 decreased cardiac index, and 115 a history of CVEs. Plasma Hcy levels were related to LV mass and ABI, after adjustment for covariates and creatinine. Significantly higher Hcy levels were found in patients with LVH (8.5 [4.4] vs 7.6 [2.8] μmol/L; adjusted P = .001) and ABI < 0.9 (10.4 [3.8] vs 7.9 [3.4] μmol/L; adjusted P = .001) than in those with LV mass and ABI within limits. Hcy levels were comparable between patients with and without carotid plaques, increased arterial stiffness, impaired endothelial, and LV pump function. Within markers of CV organ damage, only LVH was associated with a history of CVEs. CONCLUSION This study demonstrated an independent association between Hcy and LV mass as well as between LVH and a history of CVEs and suggests that LVH may represent 1 of the pathophysiologic links between Hcy and CV risk.

Long-term trajectories of anxiety and depression in patients with stable coronary heart disease and risk of subsequent cardiovascular events. Depress Anxiety 2020; 37:784-792. [PMID: 32237189 DOI: 10.1002/da.23011] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2019] [Revised: 02/14/2020] [Accepted: 03/10/2020] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND Anxiety and depression seem to be under-recognized in their importance and are often not incorporated in subsequent prevention strategies in routine clinical care of coronary heart disease. METHODS The KAROLA cohort included coronary heart disease patients participating in an in-patient rehabilitation program (years 1999/2000) and followed after 1, 3, 6, 8, 10, 13, and 15 years. We identified anxiety and depression trajectories based on the hospital anxiety and depression scale subdomains using joint latent class mixture time-to-event models. We included cardiovascular (CV) events and non-CV mortality as competing endpoints. RESULTS We included 1,109 patients (15.4% female; mean age, 59.4 (standard deviation [SD] = 8.0) years) with baseline covariate data. Over a median follow-up of 14.8 years, participants experienced 324 subsequent CV events. We identified four anxiety and depression trajectory classes, a low-stable class (52.2% and 69.6% of patients for anxiety and depression, respectively), moderate-stable class (37.6% and 23.8%), increasing class (2.3% and 3.3%), and high-stable/high-decreasing class (7.9% and 3.3%). The hazard ratio (HR) for subsequent CV events for the increasing anxiety class was 2.13 (95% confidence interval [CI], 0.61; 7.45) compared with the low-stable class after covariate adjustment. Patients following the high-decreasing anxiety trajectory showed an HR of 1.72 (95% CI, 1.11; 2.68) and patients following the high-stable depression trajectory an HR of 2.47 (95% CI, 1.35; 4.54). CONCLUSIONS Chronic high anxiety and depression trajectory classes were associated with increased risk of subsequent CV events. Assessments of both symptoms of anxiety and depression during long-term routine medical care are recommended to identify patients who would benefit from appropriate interventions.

ANNALS OF PALLIATIVE MEDICINE 2020; 9:2131-2140. [PMID: 32692226 DOI: 10.21037/apm-20-1172] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/12/2020] [Accepted: 07/08/2020] [Indexed: 11/06/2022]
Abstract
BACKGROUND Cardiovascular disease (CVD) is the most common adverse event of maintenance hemodialysis (MHD), in which serum soluble klotho plays a vital role. Tanshinone IIA (tan) has been used to protect the cardiovascular system for hundreds of years. This study was performed to investigate the effects of tan on klotho level and cardiovascular events of MHD patients. METHODS Totally 112 patients were enrolled in this study, and their demographic, clinical, and laboratory characteristics were collected at admission. Serum soluble klotho, carotid intima-media thickness (CIMT), and abdominal aorta calcification (AAC) level were measured to determine their relationship. Seventy-one patients were given sodium tan sulfonate injection according to their willingness, while 41 patients were not given any specific treatment. The endpoint events were recorded, including cardiovascular mortality, nonfatal cardiovascular events, and all-cause mortality. RESULTS All patients were divided into two groups on whether the level of serum soluble klotho was more than medium or not. CIMT and AAC grade showed significant differences between 2 groups (group of low level of klotho versus group of high level of klotho, CIMT: 1.03±0.22 vs. 0.85±0.20 mm, P<0.001; AAC grade: 5.04±3.93 vs. 1.69±2.30 points, P<0.001). All patients were followed up for at least one year. The results revealed that using tan improved the level of serum soluble klotho (490.23±153.97 pg/mL after using tan versus 444.49±143.32 pg/mL before using tan, P=0.042). Kaplan-Meier curves showed that cardiovascular event-free survival was significantly higher in patients given tan (P=0.040) compared with patients not given tan. CONCLUSIONS Tan effectively increases the level of serum soluble klotho and further reduces the incidence of cardiovascular events in MHD patients.

Abstract
BACKGROUND Identifying people with HIV (PWH) at risk for chronic kidney disease, cardiovascular events, and death is crucial. We evaluated biomarkers to predict all-cause mortality and cardiovascular events, and measured glomerular filtration rate (mGFR) slope. METHODS Biomarkers were measured at enrollment. Baseline and 5-year mGFR were measured by plasma iohexol clearance. Outcomes were a composite criterion of all-cause mortality and/or cardiovascular events, and mGFR slope. RESULTS Of 168 subjects, 146 (87.4%) had undetectable HIV load. Median follow-up was 59.1 months (interquartile range, 56.2-62.1). At baseline, mean age was 49.5 years (± 9.8) and mean mGFR 98.9 mL/min/1.73m2 (± 20.6). Seventeen deaths and 10 cardiovascular events occurred during 5-year follow-up. Baseline mGFR was not associated with mortality/cardiovascular events. In multivariable analysis, cystatin C (hazard ratio [HR], 5.978; 95% confidence interval [CI], 2.774-12.88; P < .0001) and urine albumin to creatinine ratio (uACR) at inclusion (HR, 1.002; 95% CI, 1.001-1.004; P < .001) were associated with mortality/cardiovascular events. Area under receiver operating curve of cystatin C was 0.67 (95% CI, .55-.79) for mortality/cardiovascular event prediction. Biomarkers were not associated with GFR slope. CONCLUSIONS uACR and cystatin C predict all-cause mortality and/or cardiovascular events in PWH independently of mGFR.

Abstract
Lipoprotein apheresis (LA) is an effective tool to reduce cardiovascular events (CVEs) in high-risk patients with elevations of low density lipoprotein-cholesterol (LDL-C) and/or Lipoprotein(a) (Lp(a)). All patients included into this retrospective analysis had experienced CVEs before the start of the LA therapy. We compared personal and lab data in two groups: CVEx/0 (n 60) with no new events during LA therapy, CVEx/1+ (n 48) with at least one new event. Patients of Group CVEx/1+ were about 5 years older when they had started the extracorporeal therapy, and they experienced more CVEs prior to that timepoint. There was a positive correlation between the number of CVEs before and during LA therapy. No differences were seen with respect to lipid concentrations, even after a correction of LDL-C concentrations for the LDL-C transported with Lp(a) particles. LA sessions effectively reduced both LDL-C and Lp(a). Lp(a) levels measured before LA sessions were lower than those measured initially. It appeared difficult to reach the target values for LDL-C published in the ESC/EAS Guideline in 2019, although all patients were maximally treated including drugs when tolerated. In conclusion, it will be important to initiate an LA therapy earlier, at least after a second CVE and at a younger age.

Abstract
Background Dilatation of the basilar artery ( BA ) has been recognized as a predictor of cardiovascular events ( CVE s). However, it is unclear if the longitudinal change in BA diameter (Δ BA ) is associated with CVE s. Methods and Results In a cohort of Japanese participants with vascular risk factors in an observational study, we evaluated the relationship of Δ BA to CVE s and the time course of the BA diameter. The short axis of the BA diameter was measured at the midpons level in T2-weighted images. Brain magnetic resonance imaging measurements included cerebral small-vessel disease, lacunars, and white matter hyperintensities. First, 493 patients were analyzed by the time-dependent Cox proportional hazards model to evaluate the association between Δ BA and CVE s, with adjustment for age, sex, vascular risk factors, and magnetic resonance imaging parameters. Second, we assessed the longitudinal Δ BA in 164 patients who underwent long-term follow-up magnetic resonance imaging, by linear regression analysis. In the mean follow-up of 8.7 years, 105 patients developed CVE s. A smaller Δ BA was independently associated with the high incidence of CVE s (hazard ratio, 0.36; 95% CI, 0.16-0.78; P=0.010; n=493). After a mean interval of 9.4 years, the average Δ BA was 0.41±0.46 mm (excluding patients with fetal-type circle of Willis). Progression of BA dilatation was associated with men but inversely associated with initial BA diameter and fetal-type circle of Willis (n=164). Conclusions BA diameter increased over time (excluding the patients with fetal-type circle of Willis), whereas Δ BA was inversely associated with the incidence of CVE s.

Abstract
OBJECTIVE This study was designed to investigate the effects of leukocyte Rho kinase activity and serum Cystatin C (Cys C) on cardiovascular events in patients with acute coronary syndrome (ACS). METHODS A total of 48 patients with ST-segment elevation myocardial infarction (STEMI), 23 patients with non-ST-segment elevation myocardial infarction (NSTEMI), 25 patients with unstable angina (UA) and 20 patients with no-acute coronary syndrome as control from January 2017 to June 2018 in Tianyou Hospital affiliated to Wuhan University of Science and Technology were selected in this study. Western blot was used to detect the leukocyte Rho kinase activity and Elisa kit was used to measure serum Cys C. Univariate and multivariate analysis were used to analyze the influencing factors of cardiovascular events in ACS patients. RESULTS The activity of leukocyte Rho kinase and serum Cys C were gradually reduced in the STEMI, NSTEMI and UA patients, but all significantly higher than that in No-ASC patients, and there was a positive correlation between leukocyte Rho kinase activity and serum Cys C in ACS patients (r = 0.516, P < .001). The activity of leukocyte Rho kinase was positively correlated with the levels of serum TNF-α (r = 0.634, P < .001), IL-6 (r = 0.578, P < .001), IL-8 (r = 0.582, P < .001) in ACS patients, and the level of Cys C was positively correlated with the levels of serum TNF-α (r = 0.634, P < .001), IL-6 (r = 0.578, P < .001), IL-8 (r = 0.582, P < .001) in ACS patients. Univariate and multivariate analysis showed that the leukocyte Rho kinase activity (HR = 2.994, 95%CI = 1.328-6.054, P < .0001) and the levels of serum Cys C (HR = 1.692, 95%CI = 1.028-2.124, P < .0001) were independent influencing factors of cardiovascular events in ACS patients. CONCLUSION The leukocyte Rho kinase activity and serum Cystatin C are high in acute coronary syndrome patients, and are the independent influencing factors of cardiovascular events in ACS patients.

Abstract
TG-rich lipoprotein (TRL)-related biomarkers, including TRL-cholesterol (TRL-C), remnant-like lipoprotein particle-cholesterol (RLP-C), and apoC-III have been associated with atherosclerosis. However, their prognostic values have not been fully determined, especially in patients with previous CAD. This study aimed to examine the associations of TRL-C, RLP-C, and apoC-III with incident cardiovascular events (CVEs) in the setting of secondary prevention of CAD. Plasma TRL-C, RLP-C, and total apoC-III were directly measured. A total of 4,355 participants with angiographically confirmed CAD were followed up for the occurrence of CVEs. During a median follow-up period of 5.1 years (interquartile range: 3.9-6.4 years), 543 (12.5%) events occurred. Patients with incident CVEs had significantly higher levels of TRL-C, RLP-C, and apoC-III than those without events. Multivariable Cox analysis indicated that a log unit increase in TRL-C, RLP-C, and apoC-III increased the risk of CVEs by 49% (95% CI: 1.16-1.93), 21% (95% CI: 1.09-1.35), and 40% (95% CI: 1.11-1.77), respectively. High TRL-C, RLP-C, and apoC-III were also independent predictors of CVEs in individuals with LDL-C levels ≤1.8 mmol/l (n = 1,068). The addition of RLP-C level to a prediction model resulted in a significant increase in discrimination, and all three TRL biomarkers improved risk reclassification. Thus, TRL-C, RLP-C, and apoC-III levels were independently associated with incident CVEs in Chinese CAD patients undergoing statin therapy.

Abstract
The prevalence of isolated diastolic hypertension (IDH) has been increased in hypertensive subjects with the new 2017 ACC/AHA blood pressure treatment guidelines to 6.5% from 1.3% by the JNC-7 guidelines. However, its clinical significance as a cause of adverse cardiovascular (CV) events especially in older subjects has been debated by several investigators, who have demonstrated no adverse CV effects of untreated IDH, but not by others. It is also more common in the young subjects who are at low CV risk and quite rare in the older subjects, who are at increased CV risk. Treatment of IDH in the older subjects could increase the CV complications due to a J-curve effect and, in addition, could increase the incidence of stroke from further lowering the normal systolic blood pressure (SBP). Very low SBP and DBP cannot be sustained by the cerebral blood flow autoregulation and could lead to cerebral ischemia. In order to get a better perspective of the current status of the treatment of IDH, a review of the English language literature of the available studies was conducted and 12 papers with pertinent information were retrieved. The analysis of results from these studies suggests that IDH is associated with adverse CV events in younger persons and it should be treated. In contrast, the prevalence of IDH is low in older subjects and is not associated with adverse CV events in the majority of cases. Thus, its further lowering should be avoided to prevent further decrease in normal SBP and prevent the onset of adverse CV events. However, the decision to treat IDH in older subjects should be individualized.

Abstract
OBJECTIVE To characterize cardiovascular (CV) risk factors and outcomes among incident cases of systemic sclerosis (SSc) in a population-based cohort. METHODS Medical records of patients with SSc diagnosed in Olmsted County, Minnesota, between January 1, 1980, and December 31, 2016, were reviewed to identify 78 incident SSc cases. The comparators were 156 sex- and age-matched individuals from the same population. Data for SSc characteristics, traditional CV risk factors, and CV events were collected. Cumulative incidence was adjusted for the competing risk for death. RESULTS During a median follow-up of 9.8 (SSc) and 9.2 years (non-SSc), 21 patients with SSc and 17 patients without SSc developed CV events, corresponding to 10-year cumulative incidence of 24.4% and 15.2%, respectively. The risk for incident CV disease was increased by 2-fold (hazard ratio, 2.38; 95% CI, 1.28-4.43) in patients with SSc vs comparators, predominately due to coronary artery disease (hazard ratio, 2.35; 95% CI, 1.17-4.71). Mean body mass index and prevalence of diabetes mellitus were lower in SSc vs non-SSc. There was no significant difference in smoking, hypertension, or hyperlipidemia. Observed CV events were increased compared with CV events predicted by the Framingham Risk Score and American College of Cardiology/American Heart Association score with standardized incident ratios of 4.16 (95% CI, 2.16-7.99) and 5.69 (95% CI, 2.71-11.94), respectively. CONCLUSION Patients with SSc are at >2-fold increased risk for experiencing a CV event compared with persons without SSc. Framingham Risk Score and American College of Cardiology/American Heart Association score dramatically underestimate CV risk in SSc.
