BACKGROUND Right ventricular (RV) dysfunction in ischemic cardiomyopathy (ICM) is associated with poor prognosis, but RV assessment by conventional echocardiography remains difficult. We sought to validate RV global longitudinal strain (RVGLS) and global longitudinal strain rate (RVGLSR) against cardiac magnetic resonance (CMR) and outcome in ICM. METHODS(More)
Heart failure is a major clinical problem in developed countries with about half of heart failure patients exhibiting decreased left ventricular systolic function. The correct identification and prompt treatment of some specific etiologies can reverse heart failure, and recognition of myocardial recovery may avoid long-term therapy. However, the(More)
Introduction Pulmonary arterial hypertension (PAH) is a progressive disease that can cause right ventricular (RV) dilatation and dysfunction as a result of increased pulmonary vascular resistance (PVR) and pulmonary arterial (PA) pressure. Background and Objectives: Right ventricular longitudinal strain (RVLS) is a new parameter of RV function. We evaluated(More)
OBJECTIVE We sought to assess the impact of myocardial scar burden (MSB) on the association between implantable cardioverter defibrillator (ICD) implantation and mortality in patients with ischaemic cardiomyopathy (ICM) and left ventricular EF ≤ 40%. In addition, we sought to determine the impact of gender on survival benefit with ICD implantation. DESIGN(More)
Global left ventricular remodeling, extent of inferior wall infarct, and mitral valve geometry are important predictors of mitral regurgitation severity than total infarct size in advanced ischemic cardiomyopathy
