摘要:

目的：探讨左室质量指数（LVMI）与冠状动脉心肌桥的关系。方法：回顾性分析行冠状动脉造影术患者中诊断为心肌桥的94例患者的临床资料，依据心肌桥收缩期压缩程度分为3组；选择行冠状动脉造影除外冠心病的正常对照组患者58例，所有患者均行超声心动图，评价左室质量分数与心肌桥的相关性及左室质量分数与心肌桥压缩程度的相关性。结果：冠状动脉心肌桥检出率为11.1%，多见于左前降支中段；心肌桥组左室质量指数明显大于正常对照组（74.96±16.04 vs 82.82±16.26，P＜0.01）；心肌桥亚组中3级亚组左室质量指数明显大于1、2级亚组（93.19±13.16 vs 80.38±16.85 vs 82.46±14.90，P＜0.01），差异有统计学意义。结论：冠状动脉心肌桥最常发生于左前降支中段；左室质量指数与心肌桥收缩期压缩程度呈正相关。

Abstract:

Objective：To study the relationship between the level of left ventricular mass index（LVMI） and coronary myocardial bridging . Methods：A total of 94 patients were recruited in this study who accepted diagnostic coronary angiography and were diagnosed with myocardial bridging. And the patients were divided into 3 groups with 58 patients with normal coronary angiography served as control group. Two-dimensional echo Doppler study was done on all patients to analyse the relationship between LVMI and systolic compression. Results：The depiction rate of coronary myocardial bridging was 11.1%， and most commonly localized in the middle segment of the left anterior descending branch ；The level of LVMI in myocardial bridging group was significantly higher as compared to the control group（74.96±16.04 vs 82.82±16.26，P＜0.01）. Significant differences were found between subgroup 3 and subgroup1,2 (93.19±13.16 vs 80.38±16.85 vs 82.46±14.90，P＜0.01). Conclusion：Coronary myocardial bridging is most commonly localized in the middle segment of the left anterior descending branch. The level of LVMI is positively correlated with systolic compression.
