Myocardial bridges have been detected for three or four years, and they can live for several years.

Patients with myocardial bridges generally do not affect their life expectancy if myocardial ischemia or myocardial infarction does not occur, and when myocardial ischemia or myocardial infarction does occur, long-term life expectancy can be obtained after timely treatment; in a very small number of patients, severe stenosis of myocardial bridges may lead to sudden death. A myocardial bridge is a coronary artery that travels partially within the myocardium, and when the myocardium contracts, it can compress the coronary artery causing stenosis or even occlusion, which leads to ischemia or even necrosis of the corresponding myocardium supplied. In most patients, myocardial bridges are located in the distal segment of the vessel or the degree of stenosis is not severe, which has less impact on the patient and can generally obtain a normal life span. In a small number of patients, myocardial bridges are located in the proximal to the middle segment of the anterior descending branch or have more severe stenosis during systole, which may lead to ischemia and infarction of the corresponding segment of myocardium and may endanger the patient’s life without timely treatment. In conclusion, patients with myocardial bridges are generally not serious and can be reviewed regularly, so they do not need to worry too much.
