Background Data comparing outcomes in heart failure ( HF ) across Asia are limited. We examined regional variation mortality among patients with enrolled the ASIAN ‐HF (Asian Sudden Cardiac Death Heart Failure) registry separate analyses for those reduced ejection fraction EF ; <40%) versus preserved (≥50%). Methods and Results The ‐ is a prospective longitudinal study. Participants symptomatic were recruited from 46 secondary care centers 3 Asian regions: South (India), Southeast...
Lipid-rich inflamed coronary plaques are prone to rupture. The purpose of this study was assess lipid-rich in vivo using fully integrated high-speed optical coherence tomography (OCT)/near-infrared fluorescence (NIRF) molecular imaging with a Food and Drug Administration-approved indocyanine green (ICG).An intravascular OCT/NIRF catheter dual-modal system were constructed based on clinical OCT platform. For plaques, the NIRF-emitting ICG (2.25 mg/kg) or saline injected intravenously into...
Serum uric acid (UA) has been known to have a positive association with blood pressure (BP). However, the relationship between serum UA and BP in different age groups is unclear.A total of 45,098 Koreans who underwent health examinations at Korea Association Health Promotion no history taking drugs related and/or were analyzed for determining BP.In men <40, was significantly associated systolic (β = 0.25, p 0.002) diastolic 0.41, < 0.001) after adjustment age, diabetes, dyslipidemia, body...
Background Cardiovascular disease is an important cause of mortality among survivors breast cancer (BC). We developed a prediction model for major adverse cardiovascular events after BC therapy, which based on conventional and treatment‐related risk factors. Methods Results The cohort the study consisted 1256 Asian female patients with from 4 medical centers in Korea was randomized 1:1 ratio into derivation validation cohorts. outcome measures comprised mortality, myocardial infarction,...
Background The phase angle (PhA) in bioelectrical impedance analysis (BIA) reflects the cell membrane integrity or body fluid equilibrium. We examined how PhA aligns with previously known markers of acute heart failure (HF) and assessed its value as a screening tool. Methods was measured 50 patients HF 20 non-HF controls along edema index (EI), another BIA parameter suggestive edema. Chest computed tomography-measured lung content (LFC) used to assess pulmonary congestion. A correlation...
Background: Peripartum cardiomyopathy (PPCM) is a rare disorder associated with pregnancy that can lead to life-threatening conditions. The incidence and clinical characteristics of this condition remain poorly understood. Methods Results: We aimed perform the first population-based study PPCM in South Korea, using Korea National Health Insurance Claims Database Review Assessment Service. Patients who fulfilled predefined diagnostic criteria for from January 1, 2010, December 31, 2012, were...
Summary Recently, meta‐analysis studies reported that hyperuricaemia is associated with higher incidence of type 2 diabetes mellitus (T2DM), however, there are limited data on the Asian population. The aim this observational study to estimate long‐term impact new‐onset T2DM and cardiovascular events. This based a single‐centre, all‐comers, large retrospective cohort. Subjects visited from January 2004 February 2014 were enrolled using electronic database Korea University Guro Hospital. A...
Background Coronary artery spasm ( CAS ) is a well‐known endothelial dysfunction, and major cause of vasospastic angina VSA ). The renin–angiotensin system RAS known to be closely associated with function. However, there are only few studies that investigated the impact inhibitor on long‐term clinical outcomes in patients. Methods Results A total 3349 patients no significant coronary disease, diagnosed by acetylcholine provocation test were enrolled for this study. Significant was defined as...
This cross-sectional study aimed to evaluate the association between periodontitis and cardiovascular disease (CVD) by reviewing discussing role of oral microbiome in CVD. prospective cohort used epidemiological data from Korean Genome Epidemiology Study 2004 2016. We selected 9973 patients with 125,304 controls (non-periodontitis) 173,209 participants analyzed their medical histories determine relationship cerebral stroke/ischemic heart periodontitis. The were questioned about any previous...
Adherence to oral anticoagulant therapy is essential prevent ischemic stroke in patients with atrial fibrillation (AF).
Background and Objectives: Cigarette smoking is a risk significant factor in coronary artery disease (CAD) vasospastic angina (VSA).However, it largely unknown whether adds to any long-term clinical VSA patients.Subjects Methods: A total of 2797 patients without CAD underwent acetylcholine (Ach) provocation test between November 2004 October 2010.Patients were divided into three groups, based on the presence spasm (CAS) habits (non-CAS group: n=1188, non-smoking CAS n=1214, n=395).All...
We evaluated the prevalence of gastroesophageal reflux diseases (GERD) in noncardiac chest pain (NCCP) patients, risk factors for GERD, and status prescriptions GERD Korean population.This was a retrospective non-interventional observational nation-wide 45-center study. Patients with normal coronary angiogram (CAG) upper gastroendoscopy within 2 years after CAG were enrolled. The examined. Other gastrointestinal including peptic ulcer or gastritis also Risk compared between group non-GERD...
Background Beta-blockers are often not the preferred treatment for patients with vasospastic angina. However, nebivolol, beta-blocker nitric oxide-releasing effect, could theoretically improve coronary vasospasm. We compared nebivolol versus diltiazem in improving vasospasm and quality of life hypertensive angina during a 12-week follow-up. Methods Fifty-one documented were randomly allocated into 3 groups: (1) Nebivolol Group (5mg 2 weeks/10mg 10 weeks); (2) Diltiazem (90mg weeks/180mg (3)...
There is limited long-term comparative clinical outcome data concerning angiography- versus intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) in non-complex left main artery (LMCA) disease treated with the single stenting technique drug-eluting stent (DES) era.
Calcium channel blockers diltiazem and nitrate have been used as selective coronary vasodilators for patients with significant artery spasm (CAS). However, no study has compared the efficacy of alone versus long-term clinical outcomes in CAS. A total 2741 consecutive without disease positive CAS by acetylcholine (Ach) provocation test between November 2004 May 2014 were enrolled. Significant was defined a narrowing >70% incremental intracoronary injection 20, 50, 100 μg Ach into left artery....
