Abstract: AIM:To evaluate the clinical characteristics of coronary myocardial bridge. METHODS: Included in the study were 342 patients who were hospitalized in our hospital from January 2009 to December 2011 and were diagnosed as having myocardial bridge according to coronary CT angiography (CTA) and coronary angiography. RESULTS: Among the patients, 232 cases (67.8%) were superficial type of whom 118 cases were accompanied by chest oppression, whereas 61/110 cases were of deep type accompanied by the same symptoms, with no statistical significance between types. The incidence of abnormal ST-T in electrocardiogram in deep type was statistically higher than in the superficial type (P<0.05). Incidence of hypertension, diabetes, hyperlipidemia and cardiomyopathy between superficial and deep types were not statistically different. During follow-up, the incidence of deep-type recurrent angina was statistically higher than in the superficial type (P<0.05). CONCLUSION: Myocardial bridge is not rare and may be associated with angina pectoris, atherosclerosis, myocardial infarction and lethal arrythmias. Medical treatment includes β-receptor blockers and calcium channel blockers. Surgical therapy includes myotomy and coronary artery bypass grafting (CABG); stenting is still controversial.
