MB is not only an important risk factor for CAS, but also an independent predictor of Ach positive test and MINOCA. Old age, dyslipidemia and MB are independent risk factors for CAS (ACS or CAD) in men and women. MB can cause changes in coronary hemodynamics, and significant changes in coronary hemodynamics are the main cause of various complications caused by MB. MB may be an independent predictor of MACE and appears to be associated directly with myocardial infarction. In this review, the recent research progress on the relationship between MB and coronary spasm, changes in coronary hemodynamics, and MACE is reviewed, which has a certain reference value for myocardial bridge researchers and related clinical workers.展开更多
