Abstract
BACKGROUND The rapid economic development of South Korea provides a unique model to study changes in the clinical characteristics, treatment approaches, and clinical outcomes of patients with rheumatic mitral stenosis (MS) relative to socioeconomic growth. METHODS From the Multicenter mitrAl STEnosis with Rheumatic etiology (MASTER) registry, 2,337 patients diagnosed with moderate or severe rheumatic MS between January 2001 and December 2020 were analyzed. Patients were grouped into consecutive 5-year intervals based on their year of diagnosis. Clinical characteristics, echocardiographic data, and clinical outcomes were assessed. RESULTS Over 20 years, the severity of mitral stenosis increased from 79.1% to 90.2%; similarly, the average age at diagnosis increased from 54.3 to 63.0 years (all P < 0.001). Comorbidities such as hypertension and atrial fibrillation increased (6.3% to 29.5% and 41.4% to 46.9%, respectively; all P for trend < 0.05). The rate of mitral intervention within five years after diagnosis increased from 31.2% to 47.4% (P for trend < 0.001). However, clinical outcomes of rheumatic mitral stenosis deteriorated over time in the composite outcomes (log-rank test, P < 0.001). Conversely, the incidence of stroke remained stable (60.6-73.7%; P < 0.001), which might be attributed to the increased use of anticoagulation therapy. CONCLUSION This study observed an increase in patient age, comorbidities, and valve disease severity as the country transitioned from a developing to developed status. Despite a rise in mitral valve interventions, clinical outcomes deteriorated over 20 years, highlighting the need for modified treatment approaches to improve patient outcomes.

Abstract
Background and Objectives The number of people with heart failure (HF) is increasing worldwide, and the social burden is increasing as HF has high mortality and morbidity. We aimed to provide updated trends on the epidemiology of HF in Korea to shape future social measures against HF. Methods We used the National Health Information Database of the National Health Insurance Service to determine the prevalence, incidence, hospitalization rate, mortality rate, comorbidities, in-hospital mortality, and healthcare cost of patients with HF from 2002 to 2020 in Korea. Results The prevalence of HF in the total Korean population rose from 0.77% in 2002 to 2.58% (1,326,886 people) in 2020. Although the age-standardized incidence of HF decreased over the past 18 years, the age-standardized prevalence increased. In 2020, the hospitalization rate for any cause in patients with HF was 1,166 per 100,000 persons, with a steady increase from 2002. In 2002, the HF mortality was 3.0 per 100,000 persons, which rose to 15.6 per 100,000 persons in 2020. While hospitalization rates and in-hospital mortality for patients with HF increased, the mortality rate for patients with HF did not (5.8% in 2020), and the one-year survival rate from the first diagnosis of HF improved. The total healthcare costs for patients with HF were approximately $2.4 billion in 2020, a 16-fold increase over the $0.15 billion in 2002. Conclusions The study's results underscore the growing socioeconomic burden of HF in Korea, driven by an aging population and increasing HF prevalence.

Abstract
With advancements in both pharmacologic and non-pharmacologic treatments, significant changes have occurred in heart failure (HF) management. The previous Korean HF registries, namely the Korea Heart Failure Registry (KorHF-registry) and Korean Acute Heart Failure Registry (KorAHF-registry), no longer accurately reflect contemporary acute heart failure (AHF) patients. Our objective is to assess contemporary AHF patients through a nationwide registry encompassing various aspects, such as clinical characteristics, management approaches, hospital course, and long-term outcomes of individuals hospitalized for AHF in Korea. This prospective observational multicenter cohort study (KorHF III) is organized by the Korean Society of Heart Failure. We aim to prospectively enroll 7,000 or more patients hospitalized for AHF at 47 tertiary hospitals in Korea starting from March 2018. Eligible patients exhibit signs and symptoms of HF and demonstrate either lung congestion or objective evidence of structural or functional cardiac abnormalities in echocardiography, or isolated right-sided HF. Patients will be followed up for up to 5 years after enrollment in the registry to evaluate long-term clinical outcomes. KorHF III represents the nationwide AHF registry that will elucidate the clinical characteristics, management strategies, and outcomes of contemporary AHF patients in Korea. Trial Registration ClinicalTrials.gov Identifier: NCT04329234.

Abstract
BACKGROUND Post-transplant lymphoproliferative disorder (PTLD) is an important cause of morbidity and mortality in heart transplant (HTx) recipients. However, previous studies of PTLD after HTx are limited to single-center analyses or extrapolated from all solid organ transplantations. OBJECTIVES The authors analyzed the temporal trends, risk factors, and clinical outcome of de novo PTLD specifically after HTx. METHODS Using multi-institutional, multinational data from the International Society for Heart and Lung Transplantation Thoracic Organ Transplant Registry, the authors evaluated the real-world data of PTLD after HTx, transplanted between January 2000 and June 2015. Multivariable analysis was done to identify risk factors for PTLD development after HTx. RESULTS Among 28,136 HTx recipients, 1,069 (3.8%) developed PTLD within 10 years of transplantation. PTLD showed a bimodal age pattern with peak incidence in patients of pediatric age and late adulthood at transplantation. The early transplant era (2000-2007 vs 2008-2015), male recipient, and EBV donor-positive-recipient-negative match were independent risk factors of PTLD development within 3 years of transplantation, whereas maintenance therapy with cyclosporine vs tacrolimus at initial discharge was associated with a lower incidence. PTLD development within 3 years of transplantation was significantly associated with mortality (HR: 2.42 [95% CI: 2.01-2.91]; P < 0.001). Survival after PTLD diagnosis was higher in the recent transplant era. CONCLUSIONS PTLD is relatively rare, but potentially fatal, post-transplant malignancy. PTLD incidence and mortality after HTx have decreased in the recent era. Strategies to minimize the risk of PTLD, and ensure early diagnosis and effective treatment are likely to improve outcomes in HTx.

Abstract
BACKGROUND This study aimed to compare the outcomes, according to percutaneous mitral valvuloplasty (PMV) vs mitral valve replacement (MVR), of severe mitral stenosis (MS) with the updated criteria (MVA ≤ 1.5 cm2). METHODS From the Multicenter Mitral Stenosis With Rheumatic Etiology (MASTER) registry of 3140 patients, we included patients with severe MS who underwent PMV or MVR between January 2000 and December 2021 except for previous valvular surgery/intervention, at least moderate other valvular dysfunction, and thrombus at the left atrium/appendage. Moderately severe MS (MS-MS) and very severe MS (VS-MS) were defined as 1.0 cm2 < MVA ≤ 1.5 cm2 and MVA ≤ 1.0 cm2, respectively. Primary outcomes were a composite of cardiovascular (CV) death and heart failure (HF) hospitalization. Secondary outcomes were a composite of primary outcomes and redo intervention. RESULTS Among 442 patients (mean 56.5 ±11.9 years, women 77.1%), the MVR group (n = 260) was older, had more comorbidities, higher echoscore, larger left chambers, and higher right ventricular systolic pressure than the PMV group (n = 182). During a mean follow-up of 6.9 ± 5.2 years with inverse probability-weighted matching, primary outcomes did not differ, but the MVR group experienced fewer secondary outcomes (P = 0.010). In subgroup analysis of patients with MS-MS and VS-MS, primary outcomes did not differ. However, the MVR group in patients with VS-MS showed better secondary outcomes (P = 0.012). CONCLUSIONS PMV or MVR did not influence CV mortality or HF hospitalization in both MS-MS and VS-MS. However, because of increased early redo intervention in the PMV group in VS-MS, MVR would be the preferable option without clear evidence of suitable morphology for PMV.

Abstract
BACKGROUND The risks and benefits of desensitization therapy (DST) in highly sensitized mechanical circulatory support (MCS) patients are not well known. We investigated 3 year post-transplant outcomes of desensitized durable MCS patients. METHODS Among 689 consecutively enrolled heart transplantation recipients between 2010 and 2016, we categorized them into Group A (desensitized MCS patients, n = 21), Group B (desensitized non-MCS patients, n = 28) and Group C (all nondesensitized patients, n = 640). Post-transplant outcomes included the incidence of primary graft dysfunction, 3-year survival, freedom from cardiac allograft vasculopathy, nonfatal major adverse cardiac events, any treated rejection, acute cellular rejection, antibody mediated rejection (AMR) and infectious complications. RESULTS The types of DST in Groups A and B were similar and included combinations of rituximab/intravenous immunoglobulin and plasmapheresis/bortezomib. Group A, compared with Group B, showed significantly higher pre-DST panel reactive antibody (PRA) (92.2 ± 9.8 vs. 83.3 ± 15.6, P = 0.007) and higher PRA reduction after DST (-22.2 ± 26.9 vs. -6.3 ± 7.5, P = 0.015). Groups A and C showed comparable primary graft dysfunction, 3-year survival, freedom from cardiac allograft vasculopathy, nonfatal major adverse cardiac events, any treated rejection, acute cellular rejection, and AMR. Although statistically not significant, Group A showed numerically higher 3-year freedom from AMR than Group B. Infectious complications were similar in both Groups A and B. CONCLUSIONS DST for MCS patients showed significant PRA reduction, resulting in an expansion of the donor pool. The post-transplant outcome of desensitized MCS patients showed comparable clinical outcomes to non-desensitized control patients in the same study period, revealing the safety and efficacy of DST.

Abstract
Chinese spicy cabbage (CSC) is a common traditional fermented vegetable mainly made of Chinese cabbage. In addition to eating raw, boiling and stir-frying are the most common cooking methods for CSC. To identify the impacts of boiling or stir-frying on the quality of CSC, the physicochemical properties, flavor compounds, and sensory properties of CSC were analyzed. A total of 47 volatile flavor compounds (VFCs) were detected by gas chromatography-mass spectrometry. Sulfide was determined as the main flavor compound of CSC, mainly contributed by cabbage, garlic, and onion odors. The content of sulfide decreased significantly after cooking. Nonanal, geranyl acetate, and linalool were newly generated after boiling with odor activity value (OAV) > 1, and contributed fatty, sweet, fruity, and floral odors to BL-CSC. 1-Octen-3-one, 1-octen-3-ol, octanal, nonanal, and (E)-2-nonenal were newly generated after stir-frying with OAV > 1, and contributed mushroom, fatty, and green odors to SF-CSC. Diallyl trisulfide, nonanal, (E)-β-ionone, β-sesquiphellandrene, and (E)-2-decenal were considered as the potential key aroma compounds (KACs) to distinguish the CSCs after different heat treatment. After cooking, the total titratable acidity of CSC increased and the sensory properties changed significantly. This study provides valuable information and guidance on the sensory and flavor changes of thermal processing fermented vegetables.

Abstract
The classification of secondary mitral regurgitation (MR) is based on atrial functional MR (AFMR) or ventricular functional MR (VFMR) and volume changes, but the mitral leaflet coaptation angle also contributes to the MR mechanism. The clinical implications of the coaptation angle on cardiovascular (CV) outcomes have not been well evaluated. A total of 469 consecutive patients (265 AFMR vs 204 VFMR) with more than moderate MR were evaluated for the occurrence of heart failure, mitral valve operations, and CV death. The coaptation angle was assessed by measuring the internal angle between both leaflets at mid-systole using the apical 3-chamber view. A coaptation angle ≥130° was classified as leaflet flattening, and an angle <130° was classified as leaflet tethering. AFMR and VFMR were associated with higher frequencies of leaflet flattening and tethering, respectively. AFMR was more likely to be associated with older age, atrial fibrillation, and preserved ejection fraction, all of which were related to leaflet flattening. During a follow-up of 2.3 years, 83 patients had heart failure (17.7%), 21 patients underwent mitral valve operations (4.5%), and 34 patients died (7%). Compared with leaflet tethering, leaflet flattening was more significantly related to CV events, whereas CV event rates were less markedly different in A/VFMR. Irrespective of A/VFMR, leaflet flattening and atrial fibrillation were associated with a higher frequency of CV events. Adjusted analysis showed that leaflet flattening remained an independent predictor of CV events (hazard ratio 3.5, 95% confidence interval 1.11 to 4.88, p = 0.003), whereas A/VFMR did not. In conclusion, the leaflet coaptation angle in patients with functional MR could provide risk stratification superior to that of A/VFMR. Leaflet flattening appears to be associated with unfavorable clinical outcomes.

Abstract
Cardiac muscle troponin T protein binds to tropomyosin and regulates the calcium-dependent actin-myosin interaction on thin filaments in cardiomyocytes. Recent genetic studies have revealed that TNNT2 mutations are strongly linked to dilated cardiomyopathy (DCM). In this study, we generated YCMi007-A, a human induced pluripotent stem cell (hiPSC) line from a DCM patient with a p. Arg205Trp mutation in the TNNT2 gene. The YCMi007-A cells show high expression of pluripotent markers, normal karyotype, and differentiation into three germ layers. Thus, YCMi007-A-an established iPSC-could be useful for the investigation of DCM.

Abstract
BACKGROUND Valvular heart disease (VHD) is a common cause of cardiovascular morbidity and mortality worldwide; however, its epidemiological profile in Korea requires elucidation. METHODS In this nationwide retrospective cohort study from the Korean valve survey, which collected clinical and echocardiographic data on VHD from 45 medical centers, we identified 4,089 patients with VHD between September and October 2019. RESULTS The aortic valve was the most commonly affected valve (n = 1,956 [47.8%]), followed by the mitral valve (n = 1,598 [39.1%]) and tricuspid valve (n = 1,172 [28.6%]). There were 1,188 cases of aortic stenosis (AS) and 926 cases of aortic regurgitation. The most common etiology of AS was degenerative disease (78.9%). The proportion of AS increased with age and accounted for the largest proportion of VHD in patients aged 80-89 years. There were 1,384 cases of mitral regurgitation (MR) and 244 cases of mitral stenosis (MS). The most common etiologies for primary and secondary MR were degenerative disease (44.3%) and non-ischemic heart disease (63.0%), respectively, whereas rheumatic disease (74.6%) was the predominant cause of MS. There were 1,172 tricuspid regurgitation (TR) cases, of which 46.9% were isolated and 53.1% were associated with other valvular diseases, most commonly with MR. The most common type of TR was secondary (90.2%), while primary accounted for 6.1%. CONCLUSIONS This report demonstrates the current epidemiological status of VHD in Korea. The results of this study can be used as fundamental data for developing Korean guidelines for VHD.

Abstract
We aimed to investigate the characteristics and outcomes of HTx recipients with a history of pretransplant malignancy (PTM). Among 1062 HTx recipients between 1997 and 2013, 73 (7.1%) patients had PTMs (77 cancer cases). We analyzed post-HTx outcome, recurrence of PTM, and development of de novo malignancies. Post-HTx outcome included overall survival, 10-year survival, 10-year freedom from cardiac allograft vasculopathy (CAV), non-fatal major adverse cardiac events (NF-MACE), any treated rejection (ATR), acute cellular rejection (ACR), and antibody-mediated rejection (AMR). Four most common PTMs were lymphoproliferative disorders (18.2%), prostate cancers (18.2%), non-melanoma skin cancers (18.2%), and breast cancers (13.0%). Median time from PTM and HTx was 9.0 years. During a median follow-up of 8.6 years after HTx, patients with PTM, compared to those without, showed significantly higher incidence of posttransplant malignancies (43.8% vs. 20.8%, p < .001) including 9.6% (n = 7) of PTM recurrences. However, patients with PTM, compared to those without, showed comparable overall survival, 10-year survival, 10-year freedom from CAV, NF-MACE, ATR, ACR, and AMR. Therefore, a history of PTM should not disqualify patients from HTx listing, while further research is necessary for early detection of posttransplant malignancies in these patients.

Abstract
New-onset altered level of consciousness (ALC) is a challenge in real-world clinical practice. Although its presentation is nonspecific and its etiology is intricate, the term ALC is frequently used in the emergency room (ER). This study aimed to clarify and classify the etiologies and outcomes of the ALC in the ER. We retrospectively investigated ALC patients in the ER of four tertiary referral centers from February 2018 to January 2020. The etiology of ALC was comprehensively analyzed by a consortium of university professors, board-certified clinicians in neurology, emergency medicine, or internal medicine. The time point to determine the etiology of ALC was at the time of discharge from the ER. A total of 315,526 patients who visited ER due to ALC were reviewed and found 7988 eligible patients, of which 4298 (53.8%) were male and 5282 (66.1%) were older than 60. The overall mortality was 13.5%. Except undetermined, the 9 etiologies (n = 7552) were categorized into extra- (n = 4768, 63.1%) or intracranial etiology (n = 2784, 36.9%). The most common etiology of ALC in the ER was metabolic cause (n = 1972, 24.7%), followed by systemic infection (n = 1378, 17.3%). The majority of ALC in the ER was derived from extracranial etiology. ALC in the ER is a neurological manifestation of diverse etiologies; not all can be confirmed in the ER. Not only neurological but also critical systemic illnesses should be considered to assess the protean manifestations of ALC in the ER.

Abstract
BACKGROUND The effects of statin on coronary physiology have not been well evaluated. OBJECTIVES The authors performed this prospective study to investigate changes in coronary flow indexes and plaque parameters, and their associations with atorvastatin therapy in patients with coronary artery disease (CAD). METHODS Ninety-five patients with intermediate CAD who received atorvastatin therapy underwent comprehensive physiological assessments with fractional flow reserve (FFR), coronary flow reserve, index of microcirculatory resistance, and intravascular ultrasound at the index procedure, and underwent the same evaluations at 12-month follow-up. Optimal low-density lipoprotein cholesterol (LDL-C) was defined as LDL-C <70 mg/dL or ≥50% reduction from the baseline. The primary endpoint was a change in the FFR. RESULTS Baseline FFR, minimal lumen area, and percent atheroma volume (PAV) were 0.88 ± 0.05, 3.87 ± 1.28, 55.92 ± 7.30, respectively. During 12 months, the percent change in LDL-C was -33.2%, whereas FFR was unchanged (0.87 ± 0.06 at 12 months; P = 0.694). Vessel area, lumen area, and PAV were significantly decreased (all P values <0.05). The achieved LDL-C level and the change of PAV showed significant inverse correlations with the change in FFR. In patients with optimally modified LDL-C, the FFR had increased (0.87 ± 0.06 vs 0.89 ± 0.07; P = 0.014) and the PAV decreased (56.81 ± 6.44% vs 55.18 ± 8.19%; P = 0.031), whereas in all other patients, the FFR had decreased (0.88 ± 0.05 vs 0.86 ± 0.06; P = 0.025) and the PAV remained unchanged. CONCLUSIONS In patients with CAD, atorvastatin did not change FFR despite a decrease in the PAV. However, in patients who achieved the optimal LDL-C target level with atorvastatin, the FFR had significantly increased with decrease of the PAV.

Abstract
BACKGROUND AND OBJECTIVES Real-world trends in the utility and type of gatekeeping studies in invasive coronary angiography (ICA) requires further investigation. METHODS We identified outpatients who underwent noninvasive cardiac tests or directly ICA for suspected coronary artery disease (CAD) from the nationwide Korea Health Insurance Review and Assessment Service-National Patient Sample database between 2012 and 2018. RESULTS Among 71,401 patients, the percentage of patients who were evaluated for suspected CAD was 34.7% for treadmill test (TMT), 4.2% for single-photon emission computed tomography (SPECT), 24.2% for coronary computed tomography angiography (CCTA), 1.6% for multiple gatekeepers, and 32.3% for directly ICA without noninvasive studies. The proportion of CCTA as a gatekeeper showed linear increase, (18.6% in 2012 and 28.8% in 2018; p<0.001), while those of TMT, SPECT, and direct ICA have decreased (p<0.001, p=0.03, and p<0.001, respectively). The overall incidence of downstream ICA after gatekeeper was 13.8% (6,662/48,346), and SPECT showed higher ICA rate in pairwise comparison with TMT and CCTA (p<0.001). Patients who performed gatekeepers before ICA showed higher rate of subsequent PCI (34.7% vs. 32.3%; p<0.001) and CABG (3.5% vs. 1.0%; p<0.001), compared to those who directly underwent ICA, and CCTA was associated with higher revascularization rate after ICA in pairwise comparison with TMT and SPECT (p<0.001). CONCLUSIONS Nationwide database demonstrated that CCTA is utilized increasingly as a gatekeeper for ICA and is associated with high revascularization rate after ICA in outpatients with suspected CAD.

Abstract
Abstract
Background
Difference in proteomic expression according to the etiology of cardiomyopathies is not well known.
Purpose
We aimed to identify proteome based pathogenesis in patients with biopsy proven cardiomyopathies.
Methods
Comparative proteomic analysis of biopsy specimens were performed from 9 patients with cardiomyopathy (3 dilated cardiomyopathy (DCM), 2 hypertrophic cardiomyopathy (HCM) and 4 myocarditis) as well as 5 controls (normal endomyocardial biopsy specimen from one-year surveillance of heart transplant recipients) by tandem mass tag combined with liquid chromatography-mass spectrometry. Differential expression protein analysis, gene ontology analysis and Ingenuity pathway analysis were done to discover molecular mechanism for the differentially expressed proteins in each cardiomyopathy compared to the control.
Results
Differential expression protein analysis showed higher proportion of significantly increased proteins (Log2 fold change ≥1) in HCM and myocarditis, whereas higher proportion of significantly decreased proteins (Log2 fold change ≤−1) in DCM compared to controls (Figure). According to the gene ontology analysis, upregulation of neutrophil degranulation, and down-regulation of mitochondrial translation protein was noted in patients with DCM. In patients with HCM, platelet degranulation protein was increased, and mitochondrial ATP synthesis coupled electron transport, was decreased. In patients with myocarditis, neutrophil related proteins and calcium ion binding protein was increased, but muscle cell development, protein was decreased. Ingenuity pathway analysis revealed downregulation of oxidative phosphorylation and upregulation of sirtuin signalling pathway both in DCM and HCM. In myocarditis, various pathways related to inflammation were upregulated with only RHO GDP dissociation inhibitors downregulated.
Conclusions
This study showed that each cardiomyopathy exhibited different proteomic expression compared to normal heart. Further large detailed study is needed to understand the association between proteomic expression and disease pathophysiology.

Abstract
BACKGROUND The ability of adenosine stress myocardial contrast echocardiography (AS-MCE) to reveal decreased coronary blood flow or perfusion defects (PDs) has not been explored for clinical implications after coronary revascularization. This study sought to identify the prognostic value of PDs in asymptomatic patients following percutaneous coronary intervention (PCI). METHODS We retrospectively analyzed 342 asymptomatic patients (67 years of mean age, 72% male) who underwent PCI with stents at least 9 months before AS-MCE between May 2019 and December 2020. Resting regional wall motion abnormality (rRWMA) and the patterns of PDs were assessed, and further PDs were classified as ischemic or fixed type. The primary endpoint was the composite of hospitalization for worsening heart failure, coronary revascularization, and cardiac death. RESULTS In AS-MCE (median time interval following PCI: 17.4 months), PDs were present in 93 (27.2%) out of 342 patients; 70 of ischemic PD (75.3%), 58 of fixed PD (62.4%). Those with PD showed a higher frequency of rRWMA than those without PD (53.8 vs. 15.7%, p < 0.001). During the median follow-up of 22.6 months, 26 (7.6%) patients experienced more associated clinical outcomes with PD than rRWMA. Cox analysis revealed that the combined findings of rRWMA and PD, and specifically, ischemic PD of ≥ 2 segments were associated with a high increase in adverse outcomes. CONCLUSIONS AS-MCE provided prognostic value in asymptomatic patients with prior PCI. PD might be complementary to rRWMA in risk stratification.

Abstract
Background Post-transplant malignancy (PTM) causes long-term morbidity and mortality in heart transplant (HTx) recipients. However, the detailed characteristics or predictors of PTM are not well-known. We evaluated the incidence, characteristics, long-term outcomes, and predictors of de novo PTM using a single center large-volume database. Methods We retrospectively analyzed the types and characteristics of de novo PTM in 989 patients who underwent HTx. Univariate and multivariate logistic regression analyses were used for the PTM prediction model. Results Two hundred and six patients (20.8%) had de novo PTMs (241 cancers) during a median follow-up of 11.5 years. PTM patients were older than non-PTM patients, received immunosuppressive therapy for a longer period, and were more likely to be male and white. Skin cancers were the most frequent types of malignancy (60.6%) followed by prostate (9.5%), lung (7.1%), and breast (4.1%) cancers. Although most cancers (88.8%) were surgically resected at initial presentation, about half (47.3%) recurred or progressed. Patients with skin cancer and non-skin cancer had significantly lower overall survival (P < 0.001) than patients without cancer. Older age (P < 0.001), white race (P = 0.001), and longer time receiving immunosuppressive therapy (P < 0.001) were independent predictors for PTM. Conclusion Older age, white race, and longer administration of immunosuppressive therapies were independent risk factors for PTM, which was associated with increased mortality. Further research is necessary for the prevention and early detection of PTM in HTx recipients.

Abstract
Background: Although high-risk pregnancies are common in clinical practice, there are limited data on the association of soluble suppression of tumorigenicity 2 (ST2) with pregnancy-related complications. The rates of maternal complications, including heart failure (HF) during the peripartum period, were evaluated according to the ST2 level. Methods: A single-center retrospective cohort study included and stratified 259 women with high-risk pregnancies in their early third trimester according to the ST2 levels. The primary endpoint was the occurrence of peripartum HF based on symptoms, N-terminal pro-brain natriuretic peptide, or echocardiography associated with fluid retention. The secondary endpoints consisted of pre-eclampsia, silent pleural effusion, and pericardial effusion during the peripartum period. We performed a logistic model for the association between ST2 and maternal complications. Results: Of the 259 patients (mean age: 36.4 years, mean gestational duration: 31.6 weeks), advanced age ≥35 years and twin gestation were the most prevalent risk factors. Patients with ST2 ≥ 35 ng/mL showed enlarged cardiac chambers. Peripartum HF occurred in 2 (1.6%) out of 121 patients with ST2 < 35 ng/mL and in 47 (34%) out of 138 patients with ST2 ≥ 35 ng/mL. Those with ST2 ≥ 35 ng/mL were more likely to have the secondary endpoints (40.6% vs. 5.8%, p < 0.001). After adjustment, ST2 ≥ 35 ng/mL was associated with a six-fold occurrence of peripartum HF and a four-fold increase in the secondary endpoints. Conclusions: In women with high-risk pregnancies, peripartum HF and pre-eclampsia were not uncommon, and ST2 ≥ 35 ng/mL in the third trimester was independently related to maternal complications.

Abstract
Heart failure (HF) is a clinical syndrome caused by various etiologies that results in systolic and diastolic cardiac dysfunction with congestion. While evaluating HF and planning for treatment, physicians utilize various laboratory tests, including electrocardiography, diverse imaging tests, exercise testing, invasive hemodynamic evaluation, or endomyocardial biopsy. Among these, cardiac imaging modalities and biomarkers are the mainstays during HF diagnosis and treatment. Recent developments in non-invasive imaging modalities, such as echocardiography, computed tomography, magnetic resonance imaging, and nuclear imaging, have helped us understand the etiology, pathophysiology, and hemodynamics of HF, and determine treatment options and predict the outcomes. Due to the convenience of their use and potential impact on HF management, biomarkers are increasingly adopted in our clinical practice as well as research purpose. Natriuretic peptide is the most widely used biomarker for the diagnosis of HF, evaluation of treatment response, and prediction of future outcomes. Other cardiac biomarkers to evaluate the pathophysiological mechanisms of HF include myocardial injury, oxidative stress, inflammation, fibrosis, hypertrophy, and neurohormonal activation. Because HF results from complex cardiac disorders, it is essential to assess the disease status multidimensionally. The proper utilization of multimodality imaging and cardiac biomarkers can improve the quality of patient management and predict clinical outcomes in HF in the era of personalized medicine.

Abstract
Aims We evaluated the clinical outcomes and trajectory of cardiac reverse remodelling according to the timing of sacubitril/valsartan (Sac/Val) use in patients with heart failure (HF) with reduced ejection fraction (HFrEF). Methods and results Patients with de novo HFrEF who used Sac/Val between June 2017 and October 2019 were retrospectively enrolled. Patients were grouped into the earlier use group (initiation of Sac/Val < 3 months after the first HFrEF diagnosis) and the later use group (initiation of Sac/Val ≥ 3 months after the first HFrEF diagnosis). Primary outcome was a composite of HF hospitalization and cardiac death. Secondary outcomes were HF hospitalization, cardiac death, all‐cause death, significant ventricular arrhythmia (ventricular tachycardia or ventricular fibrillation), and echocardiographic evidence of cardiac reverse remodelling including left ventricular ejection fraction (LVEF) change during follow‐up. Among 115 enrolled patients, 67 were classified in the earlier use group, and 48 were classified in the later use group. Mean period of HFrEF diagnosis to Sac/Val use was 52.1 ± 14.3 days in the earlier use group, and 201.8 ± 127.3 days in the later use group. During the median follow‐up of 721 days, primary outcome occurred in 21 patients (18.3%). The earlier use group experienced significantly fewer primary outcome than the later use group (10.4% vs. 29.2%, P = 0.010). The Kaplan–Meier survival curve showed better event‐free survival in the earlier use group than in the later use group (log rank = 0.017). There were no significant differences in cardiac death, all‐cause death, and ventricular arrhythmia between two groups (1.5% vs. 2.1%, P = 0.811; 1.5% vs. 4.2%, P = 0.375; 3.0% vs. 0%, P = 0.227, respectively). Despite a significantly lower baseline LVEF in the earlier use group (21.3 ± 6.4% vs. 24.8 ± 7.9%, P = 0.012), an early prominent increase of LVEF was noted before 6 months (35.2 ± 11.9% vs. 27.8 ± 8.8%, P = 0.007). A delayed improvement of LVEF in the later use group resulted in similar LVEF at last follow‐up in both groups (40.7 ± 13.4% vs. 39.4 ± 10.9%, P = 0.686). Although the trajectory of left ventricular remodelling showed similar pattern in two groups, left atrial (LA) reverse remodelling was less prominent in the later use group during the follow‐up period (final LA volume index: 43.6 ± 14.3 mL/m2 vs. 55.2 ± 17.1 mL/m2, P = 0.011). Conclusions Earlier use of Sac/Val was related with better clinical outcome and earlier left ventricular reverse remodelling. Remodelling of LA was less prominent in the later use group implying delayed response in diastolic function.

Abstract
INTRODUCTION High adherence to oral anticoagulants is essential for stroke prevention in patients with atrial fibrillation (AF). We developed a smartphone application (app) that pushes alarms for taking medication and measuring blood pressure (BP) and heart rate (HR) at certain times of the day. In addition to drug alarms, the habit of measuring one's BP and HR may reinforce drug adherence by improving self-awareness of the disease. This pilot study aims to test the feasibility and efficacy of the smartphone app-based intervention for improving drug adherence in patients with AF. METHODS AND ANALYSIS A total of 10 university hospitals in Korea will participate in this randomised control trial. Patients with AF, being treated with edoxaban for stroke prevention will be included in this study. Total of 500 patients will be included and the patients will be randomised to the conventional treatment group (250 patients) and the app conditional feedback group (250 patients). Patients in the app conditional feedback group will use the medication reminder app for medication and BP check alarms. The automatic BP machine will be linked to the smartphone via Bluetooth. The measured BP and HR will be updated automatically on the smartphone app. The primary endpoint is edoxaban adherence by pill count measurement at 3 and 6 months of follow-up. Secondary endpoints are clinical composite endpoints including stroke, systemic embolic event, major bleeding requiring hospitalisation or transfusion, or death during the 6 months. As of 24t November 2021, 80 patients were enrolled. ETHICS AND DISSEMINATION This study was approved by the Seoul National University Bundang Hospital Institutional Review Board and will be conducted according to the principles of the Declaration of Helsinki. The study results will be published in a reputable journal. TRIAL REGISTRATION NUMBER KCT0004754.

Abstract
Background Sudden cardiac death (SCD) and stroke-related events accompanied by atrial fibrillation (AF) can affect morbidity and mortality in hypertrophic cardiomyopathy (HCM). This study sought to evaluate a scoring system predicting cardio-cerebral events in HCM patients using cardiopulmonary exercise testing (CPET). Methods We investigated the role of a previous prediction model based on CPET, the HYPertrophic Exercise-derived Risk score for Heart Failure-related events (HyperHF), which is derived from peak circulatory power ventilatory efficiency and left atrial diameter (LAD), for predicting a composite of SCD-related (SCD, serious ventricular arrhythmia, death from cardiac cause, heart failure admission) and stroke-related (new-onset AF, acute stroke) events. The Novel HyperHF risk model using left atrial volume index (LAVI) instead of LAD was proposed and compared with the previous HCM Risk-SCD model. Results A total of 295 consecutive HCM patients (age 59.9±13.2, 71.2% male) who underwent CPET was included in the present study. During a median follow-up of 742 days (interquartile range 384–1047 days), 29 patients (9.8%) experienced an event (SCD-related event: 14 patients (4.7%); stroke-related event: 17 patients (5.8%)). The previous model for SCD risk score showed fair prediction ability (AUC of HCM Risk-SCD 0.670, p = 0.002; AUC of HyperHF 0.691, p = 0.001). However, the prediction power of Novel HyperHF showed the highest value among the models (AUC of Novel HyperHF 0.717, p<0.001). Conclusions Both conventional HCM Risk-SCD score and CPET-derived HyperHF score were useful for prediction of overall risk of SCD-related and stroke-related events in HCM. Novel HyperHF score using LAVI could be utilized for a better prediction power.

Abstract
Background: Clinical trials of non-vitamin K antagonist oral anticoagulants (NOACs) in patients with chronic heart failure and atrial fibrillation (AF) have demonstrated reduced risks of stroke and bleeding compared with vitamin K antagonists (VKAs). Here, we aim to assess the clinical efficacy and safety of rivaroxaban, a NOAC, compared with warfarin, a VKA, and the effects of rivaroxaban on cardiovascular biomarkers in patients with acute decompensated heart failure (ADHF) with reduced ejection fraction (≤40%) and AF. Methods: Rivaroxaban Once-daily vs. dose-adjusted vitamin K antagonist on biomarkers in Acute Decompensated Heart Failure and Atrial Fibrillation (ROAD HF-AF) is a randomized, open-labeled, controlled, prospective, multicenter pilot study designed to assess cardiovascular biomarkers and the safety of rivaroxaban (20 or 15 mg in patients with creatinine clearance 30-49 mL/min per day) compared with VKA (target international normalized range: 2-3) in 150 patients hospitalized with ADHF and AF. The primary endpoint is the change in circulating high-sensitivity cardiac troponin (hsTn) during hospitalization. The secondary endpoints are bleeding, hospital stay duration, in-hospital mortality, and changes in cardiovascular, renal, and thrombosis biomarkers. Patients will be followed for 180 days. Conclusion: We hypothesize that rivaroxaban will reduce myocardial injury and hemodynamic stress, as reflected by the biomarker status, within 72 h in patients with ADHF and AF, compared with VKA. We hope to facilitate future biomarker-based, large-scale outcome trials using NOACs in patients with ADHF and AF, based on the results of this multicenter, randomized, controlled study.

Abstract
Background: Heart failure with reduced ejection fraction (HFrEF) is a syndrome consisting of typical symptoms and/or signs of heart failure (HF) due to left ventricular systolic dysfunction (ejection fraction ≤40%) caused by various underlying cardiac diseases. We report conventional and recently established pharmacologic and nonpharmacologic treatments of HFrEF in this review article.Current Concepts: So far, various pharmacologic treatments have been proven beneficial in reducing HFassociated hospitalization or cardiac death. The mainstay of the treatments is renin-angiotensin-aldosterone system inhibitors, which are sympathetic nervous system blockers on top of the diuretics to relieve symptoms of systemic or pulmonary congestion. Recently, new treatment targets for natriuretic peptide and sodium-glucose cotransporter have emerged in HFrEF, allowing the use of these novel drugs in addition to the optimal conventional medications. Device therapies, such as implantable cardioverter-defibrillator and cardiac resynchronization therapy, can improve the outcome in a special population. Heart transplantation is the final treatment for patients with advanced HF. However, due to the limitation of the donor pool, mechanical circulatory support is necessary.Discussion and Conclusion: Current guidelines recommend using the four pillars of medications in HFrEF, including angiotensin-converting enzyme inhibitors (angiotensin-neprilysin inhibitors or angiotensin receptor blockers), beta-blockers, mineralocorticoid receptor antagonists, and sodium-glucose cotransporter inhibitors. Appropriate device therapy, mechanical circulatory support, and heart transplantation can enhance survival in advanced HF patients. Balanced treatment, including conventional and newer therapies, is necessary.

Abstract
Peripheral blood pressure (PBP) is usually higher than central blood pressure (CBP) due to pulse amplification; however, it is not well understood why cuff-measured PBP can be lower than CBP estimated by the late systolic pressure of radial pulse waves. We explored the implications of systolic PBP-CBP (P-CBP) differences for cardiovascular (CV) prognosis. In total, 335 patients at very high risk of atherosclerotic cardiovascular disease (ASCVD) underwent automated applanation tonometry and brachial-ankle pulse wave velocity (baPWV), and they were classified into groups according to positive or negative systolic P-CBP differences. Between-group characteristics and clinical outcomes (the composite of coronary revascularization, stroke, heart failure hospitalization, and CV death) were evaluated. Patients with negative differences had significantly higher frequency of hypertension, coronary artery disease, higher ASCVD risk burden, and elevated N-terminal pro b-type natriuretic peptide. They had higher left atrial volume index (LAVI) and lower systolic mitral septal tissue velocity (TVI-s') than those with a positive difference. These patients showed higher systolic PBP and CBP, and a higher baPWV. Multivariable analysis indicated that TVI-s', LAVI, and ASCVD risk burden were independent determinants of such systolic P-CBP differences. During a median follow-up of 12.6 months, clinical outcomes were significantly related to a negative difference (11.5% vs. 3.4%, p = 0.014), and a systolic P-CBP difference ≤ -8 mmHg was associated with a threefold higher likelihood of poor prognosis. In patients at very high risk of ASCVD, systolic P-CBP difference was associated with cardiac dysfunction and ASCVD risk burden, allowing further risk stratification.

Abstract
INTRODUCTION Pulmonary vein isolation (PVI) is the cornerstone of atrial fibrillation (AF) catheter ablation. However, a PVI alone has been considered insufficient for persistent AF. This study aimed to evaluate the efficacy of persistent AF ablation targeting complex fractionated atrial electrogram (CFAE) areas within low voltage zones identified by high-resolution mapping in addition to the PVI. METHODS We randomized 50 patients (mean age 58.4 ± 9.5 years old, 86.0% males) with persistent AF to a PVI + CFAE group and PVI only group in a 1:1 ratio. CFAE and voltage mapping was performed simultaneously using a Pentaray Catheter with the CARTO3 CONFIDENSE module (Biosense Webster, CA, USA). The PVI + CFAE group, in addition to the PVI, underwent ablation targeting low voltage areas (<0.5 mV during AF) containing CFAEs. RESULTS The mean persistent AF duration was 24.0 ± 23.1 months and mean left atrial dimension 4.9 ± 0.5 cm. In the PVI + CFAE group, AF converted to atrial tachycardia (AT) or sinus rhythm in 15 patients (60%) during the procedure. The PVI + CFAE group had a higher 1-year AF free survival (84.0% PVI + CFAE vs 44.0 PVI only, P = .006) without antiarrhythmic drugs. However, there was no difference in the AF/AT free survival (60.0% PVI + CFAE vs 40.0% PVI only, P = .329). CONCLUSION Persistent AF ablation targeting CFAE areas within low voltage zones using high-density voltage mapping had a higher AF free survival than a PVI only. Although recurrence with AT was frequent in the PVI+CFAE group, the sinus rhythm maintenance rate after redo procedures was 76%.

Abstract
The association of the soluble suppression of tumorigenicity 2 (sST2) and the prognosis of heart failure have been well evaluated. However, little is known about the prediction of sST2 for left ventricular (LV) remodeling in acute coronary syndrome (ACS). We investigated the ability of sST2 to predict LV remodeling following the revascularization of ACS. From May 2019 to December 2020, 95 patients with LV ejection fraction (EF) < 50% who underwent coronary revascularization for ACS (unstable angina, non-ST-elevation myocardial infarction, ST-elevation myocardial infarction) were enrolled. Echocardiography and sST2 were performed at baseline and at a 3-month follow-up. The association between LV remodeling, using the end-diastolic volume index, and sST2 at baseline and at the 3-month follow-up, and the difference between each value was explored. During follow-up, 41 patients showed LV adverse remodeling. The baseline sST2 increased in patients without adverse remodeling (32.05 ng/mL vs. 23.5 ng/mL, p < 0.001), although clinical characteristics were similar between the two groups. During the mean follow-up of 3 months, a significant correlation was found in the changes between sST2 and LV end-diastolic/systolic volume index (r = 0.649; p < 0.001, r = 0.618; p < 0.001, respectively), but not in the changes of LVEF (r = - 0.132, p = 0.204). The use of angiotensin-converting enzyme 2 inhibitors/receptor blockers was higher (90.7% vs. 53.7%, p < 0.001) and sST2 decreased more predominantly in patients without adverse remodeling (23.18 ng/mL vs 26.40 ng/mL, p = 0.003). However, the changes in sST2 and LV volume were not different according to the ACS types (p > 0.05, for all). Estimates of the odds ratio (OR) for remodeling according to the sST2 difference increased substantially with a negative increase in the sST2 difference. Multivariable analysis found that, the difference between the baseline and 3-month sST2 was the most important determinant of LV remodeling following the revascularization of ACS (OR 1.24; 95% confidence interval: 1.09 to 1.41; p = 0.001). In conclusion, an increase in sST2 during follow-up was a useful predictor of LV remodeling.

Abstract
OBJECTIVES We explored the hypothesis that the diagnostic performance of cardiac computed tomography (CT) throughout the full cardiac cycle would be superior to single-phase CT and comparable to transesophageal echocardiography (TEE) in diagnosing patent foramen ovale (PFO). METHODS AND RESULTS From May 2011 to April 2015, 978 patients with stroke were diagnosed with PFO by TEE. In patients with stroke, cardiac CT was performed if the patients had more than two cardiovascular risk factors. We prospectively enrolled 70 patients with an indication for cardiac CT. Cardiac CT images were reconstructed at 10% increments of the R-R interval. The sensitivity of cardiac CT throughout the full cardiac cycle in diagnosing PFO was compared to that for TEE and single-phase cardiac CT. To evaluate the specificity of cardiac CT, we analyzed patients without PFO confirmed by TEE who underwent cardiac CT within 1 month of pre-cardiac surgery. Sixty-six patients with cardiac CT and TEE were included in the final analysis. Throughout the full cardiac cycle, cardiac CT had a sensitivity of 89.4% and a specificity of 92.3% in diagnosing PFO, compared to TEE as a reference. PFO was primarily detected in the 60% and 70% intervals in 10-phase reconstructed images. The sensitivity of PFO diagnosis with cardiac CT was 81.8% when analyzing both the 60% and 70% intervals instead of the full cardiac cycle. CONCLUSION Cardiac CT throughout the full cardiac cycle outperforms single-phase cardiac CT in detecting PFO. Cardiac CT can be used as an alternative method to TEE for detecting PFO in stroke patients. KEY POINTS • Throughout the full cardiac cycle, cardiac computed tomography (CT) had a sensitivity of 89.4% and a specificity of 92.3% in diagnosing patent foramen ovale (PFO), compared to transesophageal echocardiography. • The sensitivity of diagnosing patent foramen ovale with cardiac CT was 81.8% when analyzing 60% and 70% R-R intervals instead of the full cardiac cycle. • Cardiac CT with retrospective electrocardiographic gating throughout the full cardiac cycle can increase the detectability of PFO, compared to single-phase cardiac CT.

Abstract
CeIn3, a prototypical antiferromagnet, is an ideal candidate for investigating the relationship between magnetism and superconductivity, as superconductivity is induced as the magnetic transition temperature (T N) is lowered to 0 K by applying pressure. When La is substituted for Ce, T N of CeIn3 decreases to 0 K owing to the Ce dilution effects, thereby providing an alternative route to the zero-temperature quantum phase transition. In this study, we report a combinatorial approach to gain access to the critical point by applying external pressure to 20% La-doped CeIn3. Electrical resistivity measurements of La0.2Ce0.8In3 show that the T N of 8.4 K at 1 bar is gradually suppressed under pressure and can be extrapolated to 0 K at approximately 2.47 GPa, thereby showing a similar pressure dependence of T N as shown by undoped CeIn3. The kink-like feature in resistivity at T N of CeIn3 changed to an obvious jump in the doped compound for pressures higher than 1.64 GPa, indicating depletion in the carrier density due to a gap opening. AC calorimetry measurements under applied pressure show that the size of the specific heat jump at T N decreases with increasing pressure, but any signatures associated with the gap opening are not obvious, suggesting that the pressure-induced kink-to-jump change at T N in the resistivity is not a phase transition, but rather a gradual crossover. The low-temperature specific heat divided by temperature, C/T, does not strongly diverge with decreasing temperature, but is almost saturated near the projected quantum critical point, which can be attributed to a weak enhancement in the effective mass up to 2.6 GPa.

Abstract
The objective of this study was to compare the diagnostic accuracy of office blood pressure (BP) threshold of 140/90 and 130/80 mmHg for correctly identifying uncontrolled out‐of‐office BP in apparent treatment‐resistant hypertension (aTRH). We analyzed 468 subjects from a prospectively enrolled cohort of patients with resistant hypertension in South Korea (clinicaltrials.gov: NCT03540992). Resistant hypertension was defined as office BP ≥ 130/80 mmHg with three different classes of antihypertensive medications including thiazide‐type/like diuretics, or treated hypertension with four or more different classes of antihypertensive medications. We conducted different types of BP measurements including office BP, automated office BP (AOBP), home BP, and ambulatory BP. We defined uncontrolled out‐of‐office BP as daytime BP ≥ 135/85 mmHg and/or home BP ≥ 135/85 mmHg. Among subjects with office BP < 140/90 mmHg and subjects with office BP < 130/80 mmHg, 66% and 55% had uncontrolled out‐of‐office BP, respectively. The prevalence of controlled and masked uncontrolled hypertension was lower, and the prevalence of white‐coat and sustained uncontrolled hypertension was higher, with a threshold of 130/80 mmHg than of 140/90 mmHg, for both office BP and AOBP. The office BP threshold of 130/80 mmHg was better able to diagnose uncontrolled out‐of‐office BP than 140/90 mmHg, and the net reclassification improvement (NRI) was 0.255. The AOBP threshold of 130/80 mmHg also revealed better diagnostic accuracy than 140/90 mmHg, with NRI of 0.543. The office BP threshold of 130/80 mmHg showed better than 140/90 mmHg in terms of the correspondence to out‐of‐office BP in subjects with aTRH.

Abstract
Objective The aim of this study was to investigate whether a new generic rosuvastatin is non-inferior to a proprietary one in terms of lipid-lowering efficacy. We also evaluated its non-lipid effects including adverse events. Methods One-hundred and fifty-eight patients with cardiovascular risks requiring pharmacological lipid-lowering therapy were screened. After a 4-week run-in period, 126 individuals who met the lipid criteria for drug therapy were randomly assigned to receive the new generic or proprietary rosuvastatin 10 mg daily for 8 weeks. The primary outcome variables were low-density lipoprotein-cholesterol (LDL-C) reduction and LDL-C target achievement. Hematological and biochemical parameters and adverse events were assessed. Results After 8 weeks of drug treatment, the mean percentage change in LDL-C was not different between the groups (−45.5%±19.9% and −45.1%±19.0% for generic and proprietary rosuvastatin, respectively; p=0.38). The LDL-C target achievement rate was similar between the groups (75.0% and 77.1% for generic and proprietary rosuvastatin, respectively; p=0.79). The percentage change in the other lipid profiles was not significantly different. Although generic- and proprietary rosuvastatins modestly affected creatine kinase and blood pressure, respectively, the changes were all within normal ranges. Incidence of adverse events did not differ between the receivers of the 2 formulations. Conclusion The new generic rosuvastatin was non-inferior to the proprietary rosuvastatin in terms of lipid-lowering efficacy. The rosuvastatin formulations did not exhibit clinically significant non-lipid effects with good safety profiles. Our study provides comprehensive data regarding 2 rosuvastatin formulations in East Asian subjects. Trial Registration ClinicalTrials.gov Identifier: NCT03949374

Abstract
During left ventricular opacification (LVO), myocardial contrast uptake (MCU) is frequently observed, but its clinical implication is uncertain. We aimed to investigate the diagnostic performance of MCU and its prognostic value in known or suspected coronary artery disease (CAD). Contrast echocardiography was retrospectively analyzed in 457 patients who had previous coronary angiography <12 mo before LVO. MCU was classified into replacement or interstitial patterns. Subendocardial patterns were further inspected. Events were defined as a primary composite of the occurrence of acute coronary syndrome, heart failure hospitalization, sustained ventricular tachycardia and all-cause mortality. MCU had an 87.6% sensitivity, 75.5% specificity, 73.0% positive predictive value and 87.7% negative predictive value in detecting CAD. After a median follow-up of 17.3 mo, 52 events occurred. Replacement, interstitial and subendocardial MCU patterns were associated with events. In conclusion, the presence of MCU was useful in identifying CAD and provided incremental prognostic value for clinical outcomes.

Abstract
OBJECTIVES The aim of the current study was to evaluate the long-term clinical impact of fractional flow reserve (FFR) in jailed left circumflex coronary artery (LCx) after left main coronary artery (LM) simple crossover stenting. BACKGROUND Although the provisional side-branch intervention with FFR guidance has been validated for non-LM bifurcation lesions, the outcome of such a strategy in LM bifurcation disease is not well-known. METHODS Patients who underwent LM-to-left anterior descending coronary artery simple crossover stenting and who had FFR measurements in the LCx thereafter were enrolled. A low FFR was defined as ≤0.80. The clinical outcomes were assessed by the 5-year rate of target lesion failure (TLF) (a composite of cardiac death, target-vessel myocardial infarction, or target lesion revascularization). RESULTS In 83 patients, the mean FFR of the LCx after LM stenting was 0.87 ± 0.08, and 14 patients (16.9%) had a low FFR. There was no correlation between the FFR and angiographic % diameter stenosis in jailed LCx (R2 = 0.039; p = 0.071) and there was no difference in the angiographic % diameter stenosis in the high and low FFR groups. At 5 years, the low FFR group had a significantly higher rate of TLF than the high FFR group (33.4% vs. 10.7%; hazard ratio: 4.09, 95% confidence interval: 1.15 to 14.52; p = 0.029). However, there was no difference in the clinical outcomes according to the angiographic % diameter stenosis. In a multivariate analysis, a low FFR was an independent predictor of the risk for a 5-year TLF (hazard ratio: 6.49; 95% confidence interval: 1.37 to 30.73; p = 0.018). CONCLUSIONS The patients with a high FFR in jailed LCx had better 5-year outcomes than those with a low FFR. The FFR measurement in jailed LCx can be helpful in selecting an adequate treatment strategy and may reduce unnecessary complex procedures.

Abstract
Background Patients with diabetes mellitus are at an increased risk for adverse clinical events following percutaneous coronary interventions (PCI). However, the clinical impact of diabetes mellitus (DM) on second-generation drug-eluting stent (DES) implantation is not well-known. The aim of the current analysis was to examine the clinical impact of DM on clinical outcomes and the time sequence of associated risks in patients treated with second-generation DES. Methods Using patient-level data from two stent-specific, all-comer, prospective DES registries, we evaluated 1,913 patients who underwent PCI with second-generation DES between Feb 2009 and Dec 2013. The primary outcomes assessed were two-year major cardiac adverse events (MACE), composite endpoints of death from any cause, myocardial infarction (MI), and any repeat revascularization. We classified 0–1 year as the early period and 1–2 years as the late period. Landmark analyses were performed according to diabetes mellitus status. Results There were 1,913 patients with 2,614 lesions included in the pooled dataset. The median duration of clinical follow-up in the overall population was 2.0 years (interquartile range 1.9–2.1). Patients with DM had more cardiovascular risk factors than patients without DM. In multivariate analyses, the presence of DM and renal failure were strong predictors of MACE and target-vessel revascularization (TVR). After inverse probability of treatment weighting (IPTW) analyses, patients with DM had significantly increased rates of 2-year MACE (HR 2.07, 95% CI; 1.50–2.86; P <0.001). In landmark analyses, patients with DM had significantly higher rates of MACE in the early period (0–1 year) (HR 3.04, 95% CI; 1.97–4.68; P < 0.001) after IPTW adjustment, but these findings or trends were not observed in the late period (1–2 year) (HR 1.24, 95% CI; 0.74–2.07; P = 0.41). Conclusions In the second-generation DES era, the clinical impact of DM significantly increased the 2-year event rate of MACE, mainly caused by clinical events in the early period (0–1 year). Careful observation of patients with DM is advised in the early period following PCI with second-generation DES.

Abstract
Abstract
Background
Carvedilol is one of the most effective beta-blockers in reducing ventricular tachyarrhythmias and mortality in patients with heart failure. One of the possible antiarrhythmic mechanisms of carvedilol is the suppression of store overload-induced Ca2+ release, especially for the triggered activity.
Objectives
Premature ventricular complex (PVC) originating from the ventricular outflow tract (OT) is the most common form of idiopathic PVC, and its main mechanism is related to triggered activity. We evaluate the efficacy of carvedilol to suppress the OT PVC.
Methods
The electronic medical records at our hospital were screened to identify OT PVC patients treated with carvedilol. Clinical, electrocardiographic, and Holter monitoring studies were reviewed.
Results
A total of 25 patients who underwent Holter monitoring before and after carvedilol administration were found and enrolled. The mean age of the patients was 54.9 ± 13.9 years, and the mean dose of carvedilol was 18.2 ± 10.2 mg (sustained release formulation, 8/16/32 mg). The 24-h burden of PVC in 18 (72%) of 25 patients was significantly reduced from 12.2 ± 9.7% to 4.4 ± 6.7% (P = 0.006). In seven patients, the burden of PVC was changed from 7.1 ± 6.1% to 9.8 ± 8.4% (P = 0.061). There was no difference in age, carvedilol dose, duration of treatment, ventricular function, and left atrial size between responding and non-responding groups.
Conclusion
In this retrospective pilot study, treatment with carvedilol showed PVC suppression in 72% of patients. Now, we are conducting a prospective, randomized, multicenter study to evaluate the effect of carvedilol on OT PVC (Clinical trial registration: FOREVER trial, Clinical-Trials.gov: NCT03587558).

Abstract
BACKGROUND Cardiovascular disease (CVD) is an important cause of morbidity and mortality in patients with cancer. However, the real-world CVD burden of adult cancer patients has not been well established. This study aimed to evaluate the prevalence and mortality of pre-existing and new-onset CVD in patients with cancers. METHODS We analysed the prevalence and mortality of pre-existing and new-onset CVD in 41,034 adult patients with ten common solid cancers in a single payer system using data from the Korean National Health Insurance Service-National Sample Cohort from 2002 to 2013. RESULTS When all types of cancer were included, 11.3% (n = 4647) of patients had pre-existing CVD when they were diagnosed with cancer. After excluding patients with pre-existing CVD, 15.7% of cancer patients (n = 5703) were newly diagnosed with CVD during the follow-up period (median 68 months). Both pre-existing and new-onset CVD were associated with increased risk of overall mortality and 5-year mortality. Multivariate analysis to predict all-cause mortality indicated both pre-existing and new-onset CVD, male sex, old age, prior history of diabetes or chronic kidney disease, suburban residential area, and low-income status as significant factors. CONCLUSIONS Eleven percent of cancer patients had pre-existing CVD at the time of cancer diagnosis, and about 16% of cancer patients without pre-existing CVD were newly diagnosed with CVD, mostly within 5 years after the cancer diagnosis. Proper management of pre-existing CVD is necessary and pre-emptive prevention of new-onset CVD may alter treatment options and outcomes.
