冠状动脉CTA评估心肌桥形态特征、发生位置与冠状动脉粥样硬化的关系

Evaluation of Myocardial Bridge Coronary CTA Morphological Characteris-tics, the Position Relationship with the Occurrence of Coronary Atheroscle-rosis

目的探讨冠状动脉CTA评估心肌桥形态特征、发生位置与冠状动脉粥样硬化的关系。方法方便抽取2013年4月—2015年11月该院收治的50例行冠状动脉CTA检查患者的图像资料,结合其心电图及心脏超声表现,并评估心肌桥与冠状动脉粥样硬化的关系。结果肌桥的发生率为40.00%,以前降支最为多见,占45.00%。前降支存在心肌桥的患者,血管冠状动脉粥样硬化的发生率明显高于无心肌桥的患者,差异有统计学意义(P<0.05);心肌桥近端冠状动脉粥样硬化的发生率明显高于壁冠状动脉及其远端冠状动脉粥样硬化的发生率,差异有统计学意义(P<0.05)。结论心肌桥近端动脉极易导致冠状动脉粥样硬化,可作为评估冠状动脉粥样硬化性心脏病的危险因素之一。

Objective Discussion Evaluation of myocardial bridge coronary CTA morphological characteristics, the position relationship with the occurrence of coronary atherosclerosis.Methods Convenient selection extracting April 2013 to Novem-ber 2015 were treated 50 cases of patients with coronary CTA image data, together with the ECG and cardiac ultrasound performance, and Evaluation of myocardial bridge and atherosclerosis relationship.Results The occurrence of muscular bridge was 40.00%, before descending the most common, accounting for 45.00%. LAD patients exist, coronary artery atherosclerosis incidence of myocardial bridge was significantly higher than patients without myocardial bridge（P〈0.05）;my-ocardial bridge proximal coronary atherosclerosis was significantly higher than the incidence of coronary artery wall its distal coronary atherosclerosis incidence （P〈0.05）. Conclusion Proximal arterial myocardial bridge can easily lead to coronary atherosclerosis, as one of the risk factors of coronary atherosclerotic heart disease.
