Although cardiac resynchronization therapy (CRT) is recommended for patients with moderate to severe heart failure and a prolonged QRS interval, is it ever recommended for patients with mild cardiac symptoms? Can prophylactic resynchronization therapy, delivered by an implantable defibrillator, reduce the risk of heart failure or death in those patients with mild cardiac sympotoms? Tune in to hear Dr. Arthur Moss, professor of medicine and director of the Heart Research Follow-Up Program at the University of Rochester School of Medicine and Dentistry, discuss new findings about whether CRT might play a wider role in the prevention of heart failure. Dr. Janet Wright hosts.
