BACKGROUND Optimal medical therapy can lead to left ventricular (LV) reverse remodeling (LVRR) in nonischemic dilated cardiomyopathy (NIDCM). However, because the clinical variables associated with LVRR are poorly defined, we sought to identify them and their prognostic role, and to evaluate the role of initial and midterm levels of N-terminal pro-B-type(More)
Pulse wave velocity (PWV) and augmentation index (AI) are both indirect indicators of arterial stiffness, which is an independent predictor of morbidity and mortality in cardiovascular diseases. The aim of this study was to assess the association between carotid AI (CAI), carotid-femoral PWV (CFPWV), and Framingham risk score (FRS), and to evaluate the(More)
AIMS Non-invasive echocardiographic detection of coronary artery disease (CAD), even in left main or three-vessel CAD, usually requires a stress test since regional wall motion abnormalities (RWMA) are not always evident at rest. Strain is a more sensitive parameter of myocardial systolic function and may be abnormal in patients with severe CAD. METHODS(More)
BACKGROUND Despite complete interruption of antegrade coronary artery flow in the setting of a chronic total occlusion (CTO), clinical recognition of myocardial infarction is often challenging. Using cardiac MRI, we investigated the frequency and extent of myocardial infarction in patients with CTO, and assessed their relationship with regional systolic(More)
Malignant melanoma has a very high propensity to metastasize to the heart. However, melanoma may sometimes present as a metastatic lesion in the absence of a primary lesion, which are called melanomas of unknown primary origin. We report a case in which a patient presented with a metastatic maligant melanoma in the right atrium with pericardial effusion and(More)
BACKGROUND Ischemia-modified albumin, a new marker of myocardial ischemia, is known to elevate during ischemia induced by percutaneous coronary intervention. It is, however, not known whether ischemia-modified albumin also elevates during transient coronary vasospasm. METHODS We evaluated ischemia-modified albumin in patients undergoing intracoronary(More)
BACKGROUND Clinical practice guidelines have been slowly and inconsistently applied in clinical practice, and certain evidence-based, guideline-driven therapies for heart failure (HF) have been significantly underused. The purpose of this study was to survey guideline compliance and its effect on clinical outcomes in the treatment of systolic HF in Korea.(More)
Whether the left ventricular (LV) mass index (LVMI) and LV volumetric parameters are associated independently with natriuretic peptide levels is unclear in hypertrophic cardiomyopathy (HCM). Therefore, we investigated which parameters have an independent relationship with N-terminal pro-B type natriuretic peptide (NT-proBNP) levels in HCM patients using(More)
OBJECTIVE The aim of this study was to verify the reliability and validity of the Korean language version of the Minnesota Living with Heart Failure Questionnaire (MLHFQ) before using this version in clinical practice to assess the quality of care in patients with heart failure in a cardiology clinic. METHODS The Korean versions of the MLHFQ, 36-Item(More)
We investigated whether the echocardiographic parameters of the left atrium (LA) can predict the development of nonvalvular atrial fibrillation (AF). Among 14,062 patients (>20 years old) who underwent an echocardiographic examination were evaluated, 2,606 patients who underwent follow-up ECG with an interval of >6 months were investigated. Newly developed(More)
