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.

Study questions routine use of beta blockers after heart attack

Taking beta blockers after a heart attack did not significantly reduce the risk of death or a second heart attack among people with normal heart pumping ability, as indicated by an ejection fraction of 50% or higher, according to a study presented at the American College of Cardiology's Annual Scientific Session.

Existing beta blocker investigated as novel sickle cell therapy

A beta blocker typically used to treat heart problems, hemangioma, migraines and anxiety could be a new therapeutic for patients with sickle cell disease. Researchers led by Ankit A. Desai, MD, associate professor of medicine at the Krannert Cardiovascular Research Center (KCVRC) at Indiana University School of Medicine, have been awarded a $3 million grant by the U.S. Department of Defense to evaluate the efficacy of this drug.
