冠状动脉心肌桥致主要不良心脏事件的危险因素

Analysis of risk factors for major adverse cardiac events caused by myocardial bridge

摘要

摘要:
目的探讨心肌桥致主要不良心脏事件（major adverse cardiac events，MACE）发生的危险因素。
方法收集43例前降支冠状动脉心肌桥的患者，记录住院期间的临床资料，根据是否发生MACE分为非MACE组(n=23)和MACE组(n=20)，进行回顾性分析（病例对照研究）。比较两组的基线资料和心肌桥狭窄程度、长度、厚度情况，
结果吸烟、饮酒、餐后2小时血糖、基础心率、心肌桥狭窄程度和厚度在两组间存在着差异（均P<0.05）。通过Logistic多因素回归分析发现吸烟、饮酒和心肌桥狭窄程度是预测心肌桥并发MACE的危险因素，OR值分别为11.1、10.1和5.4，且上述OR值均具有统计学意义（P<0.05）。
结论心肌桥可引发不良心脏事件，且吸烟、饮酒和心肌桥狭窄程度是心肌桥患者发生MACE的危险因素。

Abstract:
AIM To investigate the risk factors for major adverse cardiac events (MACE) caused by myocardial bridge (MB).
METHODS Clinical data of 43 MB patients in left axis deviation (LAD) were collected and related risk factors for MACE caused by MB were investigated.
RESULTS A total of 43 patients were divided into two groups according to whether they had the incidence of MACE: MACE group (23 patients) and non-MACE group (23 patients). The patients' baseline information and MB stenosis, length and thickness were compared between the two groups. The results showed that smoking, drinking, 2-hour postprandial blood glucose, resting heart rate, and MB stenosis and thickness were statistically significant between the two groups (P<0.05). Logistic regression analysis showed that smoking, drinking and MB stenosis were suspected risk factors for MACE. The OR value were 11.085, 10.095 and 5.385, respectively (P<0.05).
CONCLUSION MB can cause MACE and smoking, drinking, 2-hour postprandial blood glucose, resting heart rate, and MB stenosis and thickness of are suspected risk factors for MACE in MB patients.
