Does cardiac resynchronization therapy improve outcomes in heart failure patients with ventricular dyssynchrony?
This review summarizes the historical development, completed clinical trials, and future directions of cardiac resynchronization therapy for heart failure patients.
PURPOSE OF REVIEW: Heart failure is a major public health problem. Many heart failure patients have electrical and mechanical ventricular dyssynchrony, which are risk factors for death in heart failure patients. RECENT FINDINGS: Cardiac resynchronization therapy, by stimulating both ventricles, is a strategy to improve ventricular dyssynchrony. SUMMARY: This paper describes the historic development of this therapy; reviews the results of completed clinical cardiac resynchronization therapy studies, and discusses ongoing and future studies.
