Cardiac resynchronization for heart failure.
Cardiac conduction abnormalities may worsen heart failure by disrupting the coordination of left ventricular contraction, making it even less effective. This pathophysiologic insight suggests that judiciously applied electrical stimuli could improve the coordination and efficiency of left ventricular contraction (1). The clinical value of this new approach, called cardiac resynchronization ther...
متن کاملCardiac Resynchronization Therapy for Heart Failure
In the current issue of Circulation, Anand and colleagues representing the COMPANION (The Comparison of Medical Therapy, Pacing and Defibrillation in Heart Failure) Investigators have brought forward compelling data that emphasize the substantial morbidity benefit of cardiac resynchronization therapy (CRT) in patients with moderately severe to severe heart failure. Unlike other studies that hav...
متن کاملCardiac Resynchronization Therapy for Heart Failure
The weight of evidence supporting the routine use of cardiac resynchronization therapy, or atrial-synchronized biventricular pacing, as a treatment for patients with moderate-to-severe chronic systolic heart failure and ventricular dyssynchrony is now quite substantial. Results from mechanistic studies, observational evaluations, and randomized, controlled trials have consistently demonstrated ...
متن کاملCardiac resynchronization therapy for mild heart failure.
It has been firmly established that cardiac resynchronization therapy (CRT) reduces symptoms and improves mortality in patients with moderate-to-severe chronic heart failure [New York Heart Association (NYHA) class III-IV], despite optimal heart failure medication and with wide QRS complex on the surface electrocardiogram as evidence of ventricular dyssynchrony, but not whether such treatment i...
متن کاملCardiac resynchronization therapy in heart failure.
Cardiac resynchronization therapy (CRT) is a new therapeutic approach for a selected group of patients with symptomatic heart failure (NYHA functional class III-IV) despite optimal medical therapy, due to dilated cardiomyopathy of any etiology (left ventricular ejection fraction < or = 35% and left ventricular end-diastolic diameter > or = 55 mm), who present with electromechanical dyssynchrony...
