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.

Emotional stress may contribute to development of cancer and may also reduce effectiveness of treatments

Scientists from Wake Forest University School of Medicine are the first to report that the stress hormone epinephrine causes changes in prostate and breast cancer cells that may make them resistant to cell death.
