| 摘 要： | 目的分析单纯冠状动脉左前降支心肌桥病变对心肌供血的影响。方法 90例研究对象按冠状动脉造影特征分为3组:单纯冠状动脉左前降支心肌桥组(A组),单纯冠状动脉左前降支狭窄组(B组)及正常冠状动脉组(C组)各30例。比较3组之间的一般资料、心肌缺血表现;并采用校正的TIMI帧数(CTFC)对冠脉血流速度进行评估。结果 A组患者平均年龄低于B组(P<0.05),性别、平均血压、心率差异无统计学意义(P>0.05)。A组心肌梗死发生率、ST-T异常率低于B组(P<0.05),心绞痛表现差异无统计学意义(P>0.05)。A组CTFC较C组明显增高(P<0.05),血流速度缓慢,血流到达血管远端时间延长(P<0.05)。结论单纯冠状动脉左前降支心肌桥主要发生于年轻男性中,冠脉血流缓慢,可引起心肌缺血。

| Abstract: | Objective To analyze the impact of myocardial blood supply in patients with left anterior descending coronary artery(LAD)myocardial bridge.Methods Ninety patients were divided into three groups according to the coronary angiography: simple coronary artery myocardial bridge(group A,n=30),simple coronary artery stenosis(group B,n=30)and normal coronary artery(group C,n=30).The general materials,myocardial ischemia were observed and compared,and the coronary artery blood flow velocity and blood flow were evalu... |
