Myocardial bridges are common in the middle of the left anterior descending branch. Myocardial bridges are congenital anatomical anomalies of the coronary arteries that exist at birth. When a section of the epicardial coronary artery travels through the myocardium, this portion of the myocardium is shaped like a bridge, which is called a myocardial bridge, and myocardial bridges are commonly found in the middle section of the left anterior descending branch. Myocardial bridges are mostly single, and in a few cases, two or three of them exist at the same time. Myocardial bridges are compressed during cardiac contraction, which can result in arterial tortuosity, thus affecting distal blood flow and producing symptoms of myocardial ischemia. Myocardial bridges are present at birth, but symptoms usually appear after the age of 30-40 years. In general, mild myocardial bridges do not cause significant clinical symptoms, while some severe cases may present with symptoms such as myocardial infarction, angina pectoris, arrhythmias, etc. Typical coronary arteriographic manifestations of myocardial bridges are systolic stenosis of the epicardial arteries, which is known as the “milking” effect. Asymptomatic myocardial bridges generally do not require special treatment. Symptomatic myocardial bridges with moderate stenosis can be treated with β-blockers or nitroglycerin to dilate blood vessels; severe stenosis can be treated with stenting, which improves the hemodynamic abnormality of the myocardial bridges and ischemic symptoms. If you have chest pain, you should be alert to this disease, and it is recommended that you consult a doctor as soon as possible, complete the relevant examinations to determine the cause of the disease, and actively cooperate with the doctor for treatment.
