摘要：目的 探讨冠状动脉(冠脉)造影时心肌桥的检出率及临床意义。方法 回顾性分析2 165例冠脉造影中检出的66例心肌桥患者的临床资料。结果 心肌桥检出率为3.0%, 分布在左前降支62例。孤立性心肌桥患者58例, 其中24例无明显临床症状, 34例表现为心绞痛等临床症状; 根据冠脉管腔收缩期狭窄程度分成A、B、C 3 组, 结果显示心肌桥下血管管腔狭窄程度与临床表现有显著相关性（P＜0.05）。结论 提高心肌桥的检出率有助于减少误诊, 正确治疗。
Abstract
ABSTRACT:Objective To explore the detection rate of myocardial bridge (MB) in coronary angiography and its clinical significance. Method The clinical data of 2 165 cases who had received selective coronary angiography were studied retrospectively. Results MB was detected in 66 patients (3.0%), among whom 62 were found in left anterior descending artery. Among the 58 cases with isolated myocardial bridge, 24 had no remarkable symptoms, whereas 34 showed clinical symptoms such as angina. The arterial stenosis beneath MB was significantly correlated with clinical symptoms (P＜0.05). Conclusion The improvement of the detection rate of MB can effectively decrease misdiagnosis and benefit the treatment.
