PROGNOSTIC ROLE OF VENTRICULAR-ARTERIAL COUPLING IN PATIENTS WITH LEFT VENTRICULAR DYSFUNCTION SUBMITTED TO CARDIAC RESYNCHRONIZATION THERAPY

Background: The positive impact of cardiac resynchronization therapy (CRT) on left ventricular function in the short-term is well established, although the exact mechanism through which it modulates prognosis is still unclear. Recently ventricular-arterial coupling (VAC) has been shown to exert
