Does the myocardial bridge cause coronary spasm?

Coronary artery spasm generally refers to coronary artery spasm. Whether myocardial bridge can cause coronary artery spasm needs to be analyzed in combination with specific conditions.

If it is superficial myocardial bridge, because coronary artery is shaped in the interventricular sulcus, myocardial bridge is thin and short, it will not cause significant compression to coronary artery, and generally will not cause coronary artery spasm. However, for the deep myocardial bridge, the coronary artery usually takes shape in the ventricular septum near the right ventricle, the blood vessel position is deep, and the myocardial bridge is thick and long. When the myocardium contracts, it can cause compression to the coronary artery, which is easy to cause vasospasm, thus affecting the blood flow supply in the coronary artery, which can cause angina pectoris, myocardial ischemia and even myocardial infarction.
