Implication
Supports prophylactic ICD use in high-risk post-MI patients; extends primary-prevention evidence for sudden death.
Key Points
- This research aims to evaluate the survival benefits of implanted defibrillators in patients at high risk for ventricular tachyarrhythmia due to prior myocardial infarction.
- Assessment of patients with a prior myocardial infarction at high risk for ventricular tachyarrhythmia.
- Comparison of prophylactic therapy with implanted defibrillators against conventional medical therapy.
- Implanted defibrillator therapy significantly improves survival rates compared to conventional medical therapy.
