What are the effects of beta blockade on sudden cardiac death during acute myocardial infarction and the postinfarction period?
According to a study by Hjalmarson A (1997), beta blockade can reduce the incidence of sudden cardiac death during acute myocardial infarction and the postinfarction period. Beta blockers reduce heart rate, blood pressure, and the risk of arrhythmias, which in turn reduces the risk of sudden cardiac death due to ventricular fibrillation. Beta blockers also have anti-ischemic effects, improving coronary blood flow and reducing the risk of myocardial ischemia.
