myocardial dysfunction is a major complication in cardiac surgery that needs inotropic support. this study evaluates the effect of milrinone on patients with low ventricular ejection fraction undergoing off- pump coronary artery bypass graft (opcab). the present study is designed to evaluate the effect of milrinone on myocardial dysfunction. eighty patients with low ventricular ejection fractio...

Background and objective: Vascular obstruction and impaired blood flow and oxygen delivery cause a myocardial infarction and limit a personchr('39')s function. Therefore, finding a way to create new arteries and replace blocked arteries has always been of interest to researchers, including exercise physiologists. Therefore, this study was conducted to evaluate the effect of eight weeks of moder...

introduction: despite presence of a body of evidence in support of high accuracy of cholecystokinin cholescintigraphy (cck-cs) , for diagnosis of chronic cholecystitis(cc) , some authors have claimed that  gallbladder ejection fraction (gbef)  has poor predictive diagnostic values. the purpose of this study was to determine if there is any difference in gbef between normal individuals and patie...

background : androgens have been shown to have diverse effects on the cardiovascular system. the aim of this study was to compare androgenic hormone levels in patients with different left ventricular ejection fractions (ef). methods : the study population consisted of 515 consecutive men who were referred for angiographic studies and whose results of echocardiography and coronary angiography we...

Aims: Evidence-based guidelines for heart failure management depend mainly on current left ventricular ejection fraction (LVEF). However, fewer studies have examined the impact of prior LVEF. Patients may enter with midrange (HFmrEF) category when preserved (HFpEF) deteriorates or reduced (HFrEF) improves. In this study, we association between change in LVEF and adverse outcomes. Methods: HFmrE...

Ninety-three patients with aortic valve disease were evaluated to determine the effect of the preoperative left ventricular ejection fraction (EF) on the results of aortic valve replacement (AVR). Forty-six patients had aortic stenosis (AS), 16 had aortic insufficiency (Al), and 31 had mixed aortic stenosis and insufficiency (MX). Immediate and long-term survival curves in AS and MX, and in AS ...
