title: Sudden cardiac death in postmyocardial-infarction patients.
abstract: Patients who survive a myocardial infarction are at increased risk for sudden death, owing largely to ventricular arrhythmia. In this article, we will review the epidemiology of sudden cardiac death in postmyocardial-infarction patients, arrhythmia mechanisms and substrate leading to cardiac arrest, identifying possible risk factors for sudden cardiac death (SCD) in high risk population and apply risk stratification strategies for prevention of SCD. We will also review relevant major trials and evidence-based therapy currently used, in addition to the indications and role of implantable cardioverter-defibrillators in this population. We will end this review with a summary of the current guidelines recommendations and a look into the future of this domain.
