Core Tip

Core tip: With the deep understanding of myocardial bridge (MB), it is considered to be the reason of such complications as acute myocardial infarction, ventricular tachycardia, syncope, and sudden cardiac death. Currently, how MB affects coronary heart disease remains unclear. Computed tomography coronary angiography can directly measure MB-related coronary heart disease (CHD), which was used to explore the relationship between MB and CHD. In this study, MB thickness, systolic compression, diastolic compression, and mural coronary artery systolic stenosis were proved to be the independent influencing factors for MB-related CHD. The combination of these factors has potential diagnostic value for MB-related CHD.
