摘要

We congratulate Linde et al. (1) on the meticulously carried out REVERSE (REsynchronization reVErses Remodeling in Systolic left vEntricular dysfunction) trial that addressed the question of the clinical benefit of cardiac resynchronization therapy (CRT) in patients with New York Heart Association (NYHA) functional class II and I heart failure (1). Unfortunately, the composite primary end point as defined per the study protocol was negative. Still, the authors conclude that CRT, in combination with optimal medical treatment (+- defibrillator), reduces the risk for heart failure hospitalizations and improves ventricular structure and function in NYHA functional class II and I.
