Beta Blocker News and Research

RSS
Beta-adrenergic receptor blocking agents (beta-blockers) are drugs with multiple actions on the heart. Blockade of beta-1 receptors results in slowing of heart rate, reduction in myocardial contractility, and lowering of systemic blood pressure. In the context of acute myocardial infarction (AMI), which represents a state of reduced oxygen supply to the affected portion of the heart, these effects may be beneficial as they result in reduced myocardial workload and oxygen demand. Furthermore, beta-blockers may reduce the risk of ventricular arrhythmias, which are an important cause of death following AMI.
