Beta-blockers is the class of drugs decreases ischemia after an infarction and nonfatal acute myocardial infarction.
Reduced blood flow to the heart causes myocardial ischemia, which prevents the heart muscle from getting enough oxygen. Usually, your heart's arteries are partially or completely blocked, which causes the lower blood flow (coronary arteries).
Atherosclerosis is one of the main causes of ischemia (hardening of the arteries). The arteries become stiff and narrowed as a result of the buildup of plaque, a hard, sticky substance made primarily of fat. It lessens blood flow.
