For myocardial ischemia caused by myocardial bridges, it is best to take beta-blockers and calcium antagonists for treatment. beta-blockers include betalactone, bisoprolol, etc., and calcium antagonists include diltiazem. Because myocardial bridges are congenital coronary artery dysplasia, a section of the coronary artery travels within the myocardium and the myocardial fibers covering it are called myocardial bridges. When the heart contracts, the myocardial bridge squeezes this section of the artery, causing a decrease in blood supply to the distal end, resulting in myocardial ischemia. beta-blockers control the heart rate and reduce ischemia and hypoxia in the heart. Calcium antagonists can inhibit heart contraction, reduce oxygen consumption, dilate coronary arteries, and reduce spasm and improve blood supply.
