The Effects of 6 Minutes Walking Exercise on the Secondary Mitral Regurgitation

Abstract

Background: Mitral Regurgitation (MR) is usually insidious due to progressive remodeling of atrial and left ventricle (LV). In secondary MR, the mitral valve apparatus are structurally normal but dysfunctional because of ischemic or non-ischemic cardiomyopathy. The aim of this study was to identify echocardiographic MR variables associated with 6 Minute Walk (6MW) exercise in patients with non-ischemic cardiomyopathy.
