Effects of Cardiac Resynchronization Therapy on Ventricular Electrical Remodeling in Patients With Heart Failure.
Cardiac resynchronization therapy (CRT) reverses structural remodeling of the left ventricle. We investigated whether CRT reverses left-ventricular electrical remodeling.Eighty patients were enrolled and implanted with CRT-devices. Echocardiography and electrocardiography data were obtained from each patient prior to implantation and two years after implantation. At two years after implantation...
متن کاملCardiac 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 کاملEarly cardiac resynchronization therapy and reverse remodeling in patients with mild heart failure: is it time?
Cardiac resynchronization therapy (CRT) has been shown to consistently improve cardiac performance and exercise capacity, leading to reversal of cardiac remodeling and improvement in survival in patients with advanced heart failure and a significant ventricular conduction delay. The strategy of CRT for the treatment of advanced heart failure was secured in 2005 by the landmark Cardiac Resynchro...

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...
