Web30 de set. de 2024 · Left ventricular ejection fraction refers to the proportion of blood that is pumped out of the left ventricle with each contraction of the heart muscle. A typical normal ejection fraction is >55% or so. After injury to this muscle (e.g. after an MI), its contractility may be reduced, which can sometimes be reflected by a reduced ejection fraction. Web20 de out. de 2024 · Background Left ventricular mechanical dyssynchrony (LVMD) induced by exercise stress was reported to be clinically useful in detecting multivessel coronary artery diseases. The aim of this study was to compare the prognostic value of LVMD induced by pharmacological stress with that induced by exercise stress. Methods We …

WebMyocardial perfusion is an imaging test. It's also called a nuclear stress test. It is done to show how well blood flows through the heart muscle. It also shows how well the heart muscle is pumping. For example, after a … WebThe intraclass coefficients for the assessment of baseline LVEF, the difference between baseline and peak LVEF and peak LVEF were 0.734, 0.877 and 0.899, respectively.

Web9 de abr. de 2024 · Abnormal left ventricular contractile reserve (LVCR) is associated with adverse cardiac outcomes in different patient cohorts and might be useful in the detection of cardiomyopathy in childhood cancer survivors (CCS) after cardiotoxic treatment. The aim of this study was to evaluate LVCR by dobutamine stress echocardiography (DSE) … Web13 de out. de 2024 · LVEF, defined as the ratio of LV stroke volume to LV end-diastolic volume, is one of the most frequently measured variables in clinical practice. However, LVEF is an imperfect measure of LV contractility, affected also by preload, afterload, heart rate, and LV geometry.
