Coronary myocardial bridge is a state in which the surface of the coronary artery covers the myocardium and compresses the coronary artery when the patient is in systole, causing the patient to experience ischemia and hypoxia in the myocardial cells, inducing angina pectoris or even myocardial infarction. For coronary artery myocardial bridges, the symptoms of angina pectoris appear under the general degree, and relevant treatments need to be given, mainly beta-blockers, including metoprolol and bisoprolol, and non-dihydropyridine calcium channel blockers, such as diltiazem, which are used to slow down the ventricular rate and thus prolong the diastolic phase, so that the blood supply and oxygen supply to the myocardial cells can be improved. In addition, for severe myocardial bridging lesions, surgical related treatment needs to be given.
