Doctors often ask questions, listen to the patient’s basic condition, and confirm the diagnosis with the help of cardiac coronary angiography, multislice CT coronary imaging, electrocardiography, cardiac ultrasound and other tests. Among them, multislice CT coronary imaging and coronary angiography are the most important tests for confirming myocardial bridges. 1. Multi-slice CT Coronary Imaging: It is a test to classify myocardial bridges and evaluate whether the wall coronary arteries are stenotic and atherosclerotic by observing the length, depth and course of the coronary arteries involved in myocardial bridges. This test is radioactive and is not recommended for pregnant women or patients preparing for pregnancy. 2. Cardiac coronary angiography: By injecting angiographic agents into the patient’s peripheral arteries, the coronary arteries will be clearly visualized, and its morphology, alignment, and whether the vessels are narrowed will be observed, which will be helpful in confirming the diagnosis and differential diagnosis. Different tests have different characteristics, and patients need to choose the appropriate test to confirm the diagnosis under the guidance of the doctor.
