Some myocardial bridges are not very harmful, but some myocardial bridges have serious pressure on the bridge blood vessels, which is more harmful to the patients and may cause angina pectoris, and in serious cases, may cause myocardial infarction. Myocardial bridge if the bridge blood vessel pressure is light, may not have symptoms, and do not need special treatment, even if the long-term existence of the patient’s health and life will not have an impact. In some cases, the compression of the bridging vessels is obvious, and the patient may have clinical symptoms or even be in danger if it is severe. If the vessel compression causes myocardial ischemia, the patient will have symptoms of angina pectoris, causing chest tightness and chest pain and palpitations. Bridge blood vessel compression is serious resulting in a significant decline in blood supply, can lead to acute myocardial infarction, the condition is critical and will be dangerous. Patients with angina symptoms or the risk of infarction should be treated as soon as possible, first of all, drug therapy, giving metoprolol, diltiazem and other drug applications, usually patients pay attention to avoid overly strenuous exercise, to avoid excessive emotional fluctuations, if the effect of drug therapy is poor, you can consider surgical treatment, to lift the compression or vascular bypass. If myocardial bridges cause clinical symptoms, it is recommended to go to the cardiology department of the hospital for further consultation and treatment.
