Objectives. This study sought to characterize functional impairment after simulated ischemia-reperfusion (I/R) or Ca 2+ bolus in senescent human myocardium and to determine if age-related alterations in myocardial concentrations of SERCA2a, phospholamban, or calsequestrin participate in senescent...
Objectives. The purpose of this study was to assess the effects of enalapril and nitrendipine on the cardiac sympathetic nervous system. Background. Angiotensin-converting enzyme inhibitors and long-acting calcium channel blockers have been widely used in the treatment of cardiovascular diseases,...
Objectives. This study examined the effect of radiofrequency ablation (RFA) on left atrial (LA) and left atrial appendage (LAA) function in humans with chronic atrial flutter (AFL). Background. Atrial stunning and the development of spontaneous echocardiographic contrast (SEC) is a consequence of...
Objectives. We aimed to investigate the impact of intravascular ultrasound (IVUS)-guided stent implantation on the 6-month restenosis rate, which has not yet been fully established in randomized trials. Background. The 6-month angiographic restenosis rate was compared in patients with symptomatic...
Objectives. We used color Doppler flow mapping to determine whether vena contracta width (VCW) is a load-independent measure of the severity of mitral regurgitation. Background. VCW has been proposed to be a relatively load-independent measure of mitral regurgitation severity in flow models using...
