The application of a simple blood test to predict prognosis in acute heart failure (AHF) patients is not well established. Neutrophil-lymphocyte ratio (NLR) inexpensive and easy obtain hospitalized using routine test. We evaluate the prognostic implications NLR as an independent predictor in-hospital long-term mortality AHF patients. Among 5625 enrolled Korean Acute Heart Failure registry, 5580 were classified into quartiles by their level, analyzed for post-discharge three-year mortality....
The purpose of the present study was to describe temporal trends in prevalence and management status hypertension Korea between 1998 2015. Data adults who were aged 30 years or older extracted from National Health Nutrition Examination Survey, a nationwide representative population-based survey. Hypertension prevalent 30.5% Korean adults. age sex standardized showed little change elderly population men higher prevalence. rates awareness, treatment, control substantial improvements among...
The association between smoking cessation and cardiovascular disease (CVD) risk in relation to cumulative exposure remains poorly understood.
The 2017 American College of Cardiology/American Heart Association (ACC/AHA) hypertension guideline lowered the threshold defining and treatment target from 140/90 mmHg to 130/80 mmHg. We compared ACC/AHA Eighth Joint National Committee (JNC8) report with regard current status using Korean Health Nutrition Examination Survey. association between blood pressure (BP) control long-term major cardiovascular outcomes (MACEs) was analyzed Korea Insurance Service cohort. In cross-sectional study...
The clinical characteristics and outcomes of acute heart failure (AHF) according to left ventricular ejection fraction (LVEF) have not been fully elucidated, especially for patients with mid-range LVEF. We performed a comprehensive comparison the epidemiology, patterns in-hospital management, in AHF different LVEF categories.
Abstract This study evaluated the association of atherogenic index plasma (AIP) with platelet reactivity and clinical outcomes according to acute myocardial infarction (AMI). The composite 3-year adverse all-cause death, infarction, cerebrovascular accident was in 10,735 patients after successful percutaneous coronary intervention drug-eluting stents. AIP defined as base 10 logarithm ratio triglyceride high-density lipoprotein cholesterol concentration. High (HPR) ≥ 252 P2Y12 unit. An...
Abstract Background The impact of hypertrophic cardiomyopathy (HCM) on cardiovascular and obstetrical outcomes in pregnant women remains unclear, particularly Asian populations. This study aimed to evaluate the maternal Korean with HCM. Methods Using data from National Health Insurance Service database, we identified who gave birth via cesarean section or vaginal delivery after being diagnosed HCM between 2006 2019. Maternal were assessed based trimester pregnancy. Results included 122 158...
Abstract There is a paucity of information as to whether chromosomal abnormalities, including Down Syndrome, Turner and Klinefelter have an association with atrial fibrillation (AF) ischemic stroke development. Data from 3660 patients 2408 851 Syndrome without history AF were collected the Korean National Health Insurance Service (2007–2014). These followed-up for new-onset stroke. Age- sex-matched control subjects (at ratio 1:10) selected compared abnormalities. showed higher incidence than...
Most intravascular ultrasound (IVUS) data are stored digitally using the Digital Imaging and Communications in Medicine (DICOM) standard. This allows random access to studies improves on major limitation of conventional grayscale IVUS.We harvested 129 coronary arteries from 43 autopsied cases. Grayscale IVUS virtual histology-IVUS imaging were performed beginning 30 mm distal ostium each artery. was processed; signal intensity determined DICOM-stored images a new Medical Bench system...
Abstract Aims The aim of this study was to identify the effects a 24‐week interactive text message‐based mobile health intervention ( called ) on enhancing self‐care behaviours patients with heart failure. Background Whether can be used improve long‐term adherence among failure remains unclear. Design A quasi‐experimental pretest–post‐test design and repeated measures. Methods Data from 100 (mean age, 58.78 years; 83.0% men) were analysed. group n = 50) program over 24 weeks, which consisted...
To describe the prevalence and associated factors of pre-frailty frailty in older patients with heart failure.Secondary analysis data collected across two cross-sectional surveys on self-care behaviours failure.We analysed failure who were 60 years or (n = 407) cardiovascular outpatient clinics at tertiary medical centres South Korea between 2018 2019. Frailty was evaluated using Korean version 5-item fatigue, resistance, ambulation, illnesses loss weight (FRAIL) scale. status categorized as...
Abstract Objectives: This study investigated the association between obesity type and obstructive coronary artery disease (CAD) in postmenopausal women. Methods: Study data were obtained from a nation-wide registry, composed of 659 women older than 55 years with chest pain undergoing elective invasive angiography suspicion CAD. Obstructive CAD was defined as angiographic findings ≥50% diameter stenosis any major epicardial artery. Overall body mass index ≥25 kg/m 2 , central waist...
The effects of fenofibrate on C-reactive protein (CRP) are under debate. We investigated the effect CRP levels and variables determining changes.This case-control study enrolled 280 hypertriglyceridemic patients who were managed either with 200 mg (Fenofibrate group, n=140) or standard treatment (comparison n=140). measured before after management for 2 months.CRP decreased in both (p=0.003) comparison (p=0.048) groups. Changes not significantly different between two groups (p=0.27)...
Results: Baseline parameters except lipid profiles were similar between the fenofibrate and control groups. Creatinine levels increased in group (from 0.90±0.18 mg/dL to 1.05±0.22 mg/dL, p<0.001) did not change 0.91±0.12 0.92±0.14 p=0.39). The elevation was more pronounced than (0.15±0.12 vs. 0.02±0.11 p<0.001). Changes creatinine only associated with therapy (r=0.52, stepwise linear regression analysis. Conclusion: Fenofibrate for 1-3 years significantly hypertensive patients...
Background Cardiac valvular calcification is associated with the overall coronary plaque burden and considered an independent cardiovascular risk prognostic factor. The purpose of this study was to evaluate relationship between presence morphology and/or vulnerability. Methods Transthoracic echocardiography used assess in 280 patients artery disease who underwent radiofrequency intravascular ultrasound (Virtual Histology IVUS, VH-IVUS). A propensity score–matched cohort 192 (n = 96 each...
Objective: Lifestyle modification is crucial in managing hypertension, independent of medical treatment. This study aimed to evaluate the implementation lifestyle modifications and analyze trends among patients with hypertension Korea from 2007 2021. Design method: Data National Health Nutrition Examination Survey conducted between 2021 was analyzed. The included aged >19 years. Factors such as regular physical activity, smoking alcohol abstinence, weight stress management, adherence a...

Introduction: Cardiovascular diseases (CVD) are the leading cause of death in developed countries. Coronary artery calcium (CAC) is a clinically validated strong marker CVD, and previous studies suggest that retinal blood vessels provide relevant information. This study aimed to validate Reti-CVD model, for predicting CAC score through photographs, using datasets from Spain, Korea India. Hypothesis: We proposed hypothesis model can accurately predict scores photographs Spanish, Korean Indian...
Introduction: Reti-CVD, a novel cardiovascular risk stratification tool derived from deep learning and retinal photography, offers promising alternative to CT scan-measured Coronary Artery Calcium (CAC) scores in predicting events. This study investigates the profile of Reti-CVD using data three medical centers South Korea: GC iMED Gangbuk&Gangnam branches Philip Medical Center. Hypothesis: can effectively stratify across different age groups genders correlate with actual CAC scores,...
