How do you measure lvef
Web### Learning objectives Non-invasive evaluation of left ventricular (LV) systolic function by echocardiography remains one of the most pivotal measures in clinical cardiology. Although conventionally quantified by means of LV ejection fraction (LVEF), it has become evident that this parameter is subject to a number of limitations. LVEF can be normal in the … WebThe mean LVEF in patients randomized to placebo was 31%, and the associated 1-year mortality approximately 12%—similar to the 15% mortality reported by the MPRG in …

WebMar 1, 2014 · It has long been understood that left ventricular ejection fraction (LVEF) is a poor measure of LV systolic function because of load dependence, measurement error, and observer variability. In addition, LVEF, which is calculated from end-diastolic and end-systolic chamber volumes, is really a measure of chamber function not myocardial function.
