INTRODUCTION Action potential duration restitution (APDR) plays a role in initiation and maintenance of ventricular tachycardia (VT)/ventricular fibrillation (VF). We hypothesized that the steeply sloped APDR and its spatial heterogeneity contribute to VT/VF inducibility in patients with ventricular arrhythmia. METHOD AND RESULTS After programmed(More)
PURPOSE OF REVIEW Adipose-derived stem cells (ASCs) are readily available from autologous adipose tissue and have been demonstrated to provide significant potential for tissue rescue from, or repair of, damage in multiple animal models. These include models of myocardial infarction, heart failure, hind limb ischemia, and inflammatory conditions. Early(More)
BACKGROUND Aberrant expression of microRNAs is associated with neointimal hyperplasia (NIH) in type 2 diabetes. We prospectively compared the effects of pioglitazone on coronary NIH and changes in microRNAs according to NIH status in type 2 diabetic patients during 9-month follow-up. METHODS AND RESULTS Type 2 diabetic patients were randomly assigned to(More)
Cilostazol, a phosphodiesterase III inhibitor, is known to have anti-proliferative activity. We investigated the effects of cilostazol 200 mg, in addition to aspirin 100 mg and clopidogrel 75 mg, on carotid intima-media thickness (IMT) progression during a 2-year follow-up period in patients with acute coronary syndrome (ACS) requiring stent implantation.(More)
OBJECTIVE The purpose of this study was to characterize the relationships among plasma adiponectin, essential hypertension, left ventricular diastolic function and left ventricular hypertrophy. METHODS AND RESULTS Plasma adiponectin concentration was assessed by radioimmunoassay, and body mass index (BMI) was measured in 275 patients (138 women and 137(More)
OBJECTIVE Black raspberry (Rubus occidentalis) is known for improving vascular function. However, there has been no study evaluating its effects on 24-h systolic and diastolic blood pressure in prehypertensive patients. The aim of this study was to examine those effects. METHODS Patients with prehypertension (N = 45) were prospectively randomized into a(More)
BACKGROUND The aim of this study was to assess whether the morphological and functional changes of the left atrium (LA) differ after catheter ablation (ABL) from those after electrical cardioversion (ECV) in atrial fibrillation (AF). METHODS AND RESULTS AF patients who had maintained sinus rhythm for 3 months after either ECV (n=30) or ABL (n=33) were(More)
We compared the effects of telmisartan and valsartan on late lumen loss and inflammatory markers after sirolimus-eluting stent implantation in hypertensive patients. This was a prospective, randomized, single-blinded, 8-month follow-up study that included hypertensive patients with significant coronary artery stenosis treated with telmisartan (n=79) or(More)
BACKGROUND Plasma adiponectin is decreased in patients with coronary artery diseases, especially in patients with acute coronary syndrome (ACS). However, the correlation between plasma adiponectin and variant angina pectoris (VAP) has not been verified. Plasma adiponectin concentrations between VAP and other coronary artery diseases was compared in the(More)
OBJECTIVE Telmisartan is a peroxisome proliferator-activated receptor-γ activator with potent anti-inflammatory and antiatherogenic effects. The authors compared the effects of telmisartan and valsartan on neointima volume, atherosclerosis progression and brachial-ankle pulse wave velocity (baPWV) after stenting in hypertensive type 2 diabetes.
