Myocardial bridges, also known as myocardial bridges, occur when the normal course of the coronary arteries enters the muscle, causing a transient shortage of blood supply to the coronary arteries during muscle contraction and diastole. Symptoms include angina pectoris and a crushing pain in the back of the chest that is transient and lasts for a few seconds, rarely more than a minute. Sometimes there is also chest tightness, difficulty in breathing, and even fainting. Once these symptoms appear, it is important to go to the hospital promptly to clarify the extent of myocardial bridges through electrocardiogram, cardiac ultrasound, coronary CT, coronary angiography, and to assess whether treatment is needed, and to give the next treatment plan through these assessments so that the patient can achieve a healthy condition.
