Myocardial perfusion imaging can predict outcomes in cardiac patients. However, limited data exist regarding its prediction of cardiovascular outcomes in cancer patients. We sought to determine whether myocardial perfusion imaging predicts long-term cardiovascular outcomes in cancer patients.We performed a retrospective review of 787 consecutive patients at our institution who underwent myocard...
Background: Various therapeutic protocols have been recommended for treating dyslipidemia, particularly in patients with coronary artery disease. The purpose of this study was to assess the efficacy of statin use with or without fenofibrate on echocardiographic findings of patients with coronary artery disease and dyslipidemia.Methods: This clinical trial was conducted on 124 patients with coro...
Left ventricular ejection fraction (LVEF) has been the central parameter used for diagnosis and management in patients with heart failure. A good predictor of adverse outcomes in heart failure when below ∼45%, LVEF is less useful as a marker of risk as it approaches normal. As a measure of cardiac function, ejection fraction has several important limitations. Calculated as the stroke volume div...
AIM To determine whether measurement of serum troponin T concentration after first acute myocardial infarction can be used to identify patients with a left ventricular ejection fraction of < 40%, who have an adverse prognosis. METHODS Troponin T concentration was measured, and coronary and left ventriculography performed in 50 consecutive patients with acute myocardial infarction. Angiographi...
BACKGROUND There are no randomized, controlled trial data to support the benefit of beta-blockers in patients with asymptomatic left ventricular systolic dysfunction. We investigated whether beta-blocker therapy ameliorates left ventricular remodeling in asymptomatic patients with left ventricular systolic dysfunction. METHOD AND RESULTS Patients with left ventricular ejection fraction <40%, ...
background: this study was designed to investigate the accuracy of dobutamine stress echocardiography (dse) in detecting the post-revascularization recovery rate of contractile reserve (cr) in ischemic myocardium. methods: a total of 112 segments from seven patients with low ejection fraction (<35%) and coronary artery disease were evaluated with dse one week before and 12 weeks after coronary ...
BACKGROUND In patients with drug resistant incessant supraventricular tachycardia, radiofrequency induced ablation of the atrioventricular junction and pacemaker implantation have hitherto been considered a treatment of last resort. OBJECTIVE To assess the short and long term effects of ablation of the atrioventricular junction on systolic and diastolic left ventricular function in patients w...
OBJECTIVES This study was undertaken to determine which exercise and radionuclide ventriculographic variables predict prognosis in advanced heart failure. BACKGROUND Although cardiopulmonary exercise testing is frequently used to predict prognosis in patients with advanced heart failure, little is known about the prognostic significance of ventriculographic variables. METHODS The results of...
BACKGROUND Low-flow low-gradient (LFLG) is sometimes observed in severe aortic stenosis (AS) despite normal ejection fraction, but its frequency and mechanisms are still debated. We aimed to describe the characteristics of patients with LFLG AS and assess the presence of longitudinal left ventricular dysfunction in these patients. METHODS AND RESULTS In a multicenter prospective study, 340 co...
Background Cardiac magnetic resonance imaging (CMR) is the goldstandard technique for the assessment of right ventricular function. Recent data indicate that right ventricular ejection fraction (RVEF) <45% by CMR is a strong predictor of outcome in patients with dilated cardiomyopathy. However, the prognostic significance of RVEF in heart failure with preserved ejection fraction (HFpEF) is unkn...
