Does an implanted defibrillator improve survival in patients with coronary disease and prior myocardial infarction at high risk for ventricular arrhythmia?
Prophylactic implantation of a defibrillator improves survival in high-risk patients with prior myocardial infarction compared to conventional medical therapy.
In patients with a prior myocardial infarction who are at high risk for ventricular tachyarrhythmia, prophylactic therapy with an implanted defibrillator leads to improved survival as compared with conventional medical therapy.
Moss et al. (1996) studied this question.
