Myocardial bridges are major diseases. Most myocardial bridges are usually asymptomatic, but some patients with myocardial bridges may experience angina-like symptoms such as pain in the anterior region of the heart and chest tightness, which may lead to acute myocardial ischemia and hypoxia and thus infarction. Myocardial bridge refers to one or more coronary arteries through the myocardium rather than on its surface, when the myocardial contraction can squeeze the arteries located in the myocardium and cause myocardial ischemia, and in severe cases, it can cause ischemia, hypoxia and even infarction of distal myocytes. For symptomatic patients, we can choose to slow down the heart rate of drugs such as metoprolol tablets, nifedipine tablets and other vasodilators to alleviate the symptoms, and in severe cases, surgery is needed. The severity of myocardial bridges depends on the degree of coronary artery compression and whether there are symptoms, asymptomatic myocardial bridges can be regularly reviewed, and it is recommended to go to the hospital for further treatment if symptoms such as chest pain and chest tightness occur.
