Key result
Implantable cardioverter-defibrillators are the most reliable therapy to prevent sudden cardiac death in patients with documented ventricular tachyarrhythmias and in high-risk patients after myocardial infarction with depressed heart function.
Why the study?
Does an implantable cardioverter-defibrillator (ICD) prevent sudden cardiac death and improve survival in patients at high risk of fatal ventricular arrhythmias?
Does an implantable cardioverter-defibrillator (ICD) prevent sudden cardiac death and improve survival in patients at high risk of fatal ventricular arrhythmias?
ICD therapy is established as the most reliable treatment for preventing sudden cardiac death in high-risk patients, particularly those with depressed left ventricular function, though device-related complications remain a clinical challenge.

Supports ICD use in indicated high-risk patients; leaves open optimization of selection and complication mitigation.
Aizawa et al. (2004) conducted a review in Sudden cardiac death, ventricular tachycardia, ventricular fibrillation. Implantable Cardioverter Defibrillator (ICD) vs. Antiarrhythmic drugs was evaluated. Implantable cardioverter-defibrillators are the most reliable therapy to prevent sudden cardiac death in patients with documented ventricular tachyarrhythmias and in high-risk patients after myocardial infarction with depressed heart function.
