In 61 patients (77 studies) who had a transmural myocardial infarction, we compared the left ventricular ejection fraction by echocardiography with the ejection fraction determined by a computerized radioisotope technique that makes no assumptions regarding left ventricular geometry. In 31 studies of 26 patients with normal left ventricular wall motion by videotracking and normal left heart siz...
introduction: cardiovascular abnormalities have been reported in liver cirrhosis (lc). in these patients, cardiac symptoms and physical signs occur as the liver functions worsen. cirrhosis is associated with hyper dynamic circulation and beta-adrenergic system changes responsible for the cardiovascular abnormalities. the purpose of the present study was to explore the echocardiographic findings...
BACKGROUND The prevalence and clinical outcomes of heart failure with preserved left ventricular ejection fraction after acute myocardial infarction have not been well elucidated. OBJECTIVE To analyze the prevalence of heart failure with preserved left ventricular ejection fraction in acute myocardial infarction and its association with mortality. METHODS Patients with acute myocardial infa...
OBJECTIVE To investigate the value of Simpson's rule, Teichholz's formula, and recording of mitral ring motion in assessing left ventricular ejection fraction (EF) in patients with left ventricular hypertrophy. DESIGN Left ventricular ejection fraction calculated by Simpson's rule and by Techholz's formula and estimated by mitral ring motion was compared with values obtained by radionuclide a...
Abstract Background Myocardial iron overload is the leading cause of death in patients with beta-thalassemia major. Combined therapy with deferiprone(DFP) and desferrioxamine (DFO)were suggested to be more effective than deferasirox(DFX) for removing heart iron. Deferasirox has recently been made available, but its long-term efficacy on cardiac function has not yet been established. Our study...
Background:Cardiac rehabilitation program (CRP) is a useful method of modifying cardiovascular risk factors, improving life expectancy and quality of life in patients with ischemic heart disease (IHD). The present study was conducted to evaluate the effects of cardiac rehabilitation on the pulmonary artery systolic pressure (PASP) and left ventricular end-diastolic pressure (LV...
OBJECTIVE The association between biochemical markers and left ventricular ejection fraction in patients with myocardial infarction was not completely studied. Our goal is to study the association between biochemical markers and left ventricular dysfunction in patients with ST-elevation acute myocardial infarction. METHODS With an observational and prospective design we included patients with...

RATIONALE Although transient reduction in the left ventricular ejection fraction is characteristic of Takotsubo cardiomyopathy, little is known about the time-course changes of myocardial deformation in coronary vasospasm-related Takotsubo cardiomyopathy. PATIENT CONCERNS We retrospectively analyzed the time-course changes in left ventricle, right ventricle, and left atrium strain values in a...
The effect of oral propranolol on left ventricular ejection fraction, left ventricular volumes, cardiac output, and segmental wall motion was assessed with multigated blood pool imaging both at rest and during supine exercise in 15 patients with angina pectoris. Propranolol had no effect on resting left ventricular ejection fractions. Before propranolol, they did not change during exercise, whe...
