Cardiac-Resynchronization Therapy with or without an Implantable Defibrillator in Advanced Chronic Heart Failure

Key Result

Cardiac-resynchronization therapy significantly reduces mortality in advanced heart failure patients when combined with an implantable defibrillator.

Key Points

• This research aims to evaluate the effectiveness of cardiac-resynchronization therapy alone versus in combination with an implantable defibrillator in patients with advanced heart failure.
• Participants included patients with advanced heart failure and a prolonged QRS interval.
• The study tested cardiac-resynchronization therapy with and without an implantable defibrillator.
• Outcomes assessed included mortality and hospitalization rates.
• Cardiac-resynchronization therapy significantly decreased the risk of death from any cause.
• Combining therapy with an implantable defibrillator significantly reduced mortality rates.
