Beta-blockers lower heart rate and blood pressure and reduce the workload on the heart. This in turn can help relieve or prevent chest pain and discomfort (angina). Beta-blockers are often used with other medicines to treat a heart attack in progress.
Beta-blockers are also taken after a heart attack for a long time—maybe for the rest of your life—to lower the risk of sudden death.
