A Novel Echocardiographic Parameter for Predicting the Ischemic Etiology of Cardiomyopathy and Its Prognosis in Patients with Congestive Heart Failure

A high degree of heterogeneity of e′, expressed as Ve′, provides incremental value over clinical variables and conventional echocardiography to predict the prevalence of low left ventricular ejection fractions patients with ICM. Furthermore, elevated Ve′ could also identify patients at a high risk for cardiac mortality.
