The depth of myocardial bridges can be seen on CT films and can be viewed by coronary CTA. Myocardial bridges are divided into superficial and longitudinal types.
1. Superficial type: superficial myocardial bridges are thin and short, the degree of compression of coronary vessels is relatively mild, the impact on coronary blood flow is small, and ECG changes are not obvious. Usually, patients do not have symptoms such as myocardial ischemia, and try to avoid strenuous activities in daily life to avoid insufficient blood supply due to increased heart rate.
2. Longitudinal type: longitudinal type myocardial bridge is thick and long, the coronary artery vessels are compressed to a heavier degree, which has a great influence on coronary blood flow, and angina pectoris occurs, and the electrocardiogram shows characteristic changes. The patient’s low-salt diet can reduce the burden on the heart to some extent.
Myocardial bridge has a certain impact on the cardiovascular, daily attention is needed, if there is chest tightness, chest pain and other uncomfortable symptoms, should promptly seek medical treatment.
