1. In patients with heart failure, reduced left ventricular ejection fraction, and prolonged QRS>130 ms, treatment with cardiac resynchronization therapy (CRT), in addition to implantable cardioverter-defibrillator (ICD), significantly reduced the risk of heart failure events when compared with patients only receiving ICD. 2. The rates of device-related complications were similar...

1. In patients with left bundle-branch block (LBBB) and QRS duration of 130-149 milliseconds (ms), women had a significant reduction in the end-point of heart failure and death, while men had no significant benefit, when receiving CRT-defibrillator (CRT-D) therapy.  2. Neither sex benefited from CRT-D therapy if they had a...

Image: PD  1. Heart failure patients with left bundle branch block (LBBB) and QRS durations of 150 ms or greater had better outcomes after cardiac resynchronization defibrillator placement. Patients with both LBBB and QRS > 150ms had 3-year mortality of 20.9%, while patients with neither had 3-year mortality of 32.3%.  2....
