Arthur Moss, M.D., Professor of Medicine at the University of Rochester Medical Center and Principal Investigator of the trial, presented the MADIT-CRT data. The primary endpoint showed that Boston Scientific's cardiac resynchronization therapy defibrillators (CRT-Ds) were associated with a 34 percent relative reduction in the risk of all-cause mortality or first heart failure event in asymptomatic and mild (NYHA Class I and II1) heart failure patients, when compared to standard implantable cardioverter defibrillators (ICDs) (p=0.001).
