【摘要】：目的研究320排冠状动脉CT血管造影(CCTA)诊断的心肌桥患者的预后。方法将2008年8月至2010年12月行CCTA的患者作为研究对象,分为3组:冠状动脉完全正常组、冠状动脉存在斑块组及单纯心肌桥组进行随访。随访的终点事件为心源性死亡、非致死性AMI、需住院的不稳定型心绞痛、因心肌缺血症状或客观证据而接受血运重建治疗、其他原因的死亡。对随访的结果进行生存分析。结果最终入选的326例患者,年龄(66.6±11.8)岁,男性184例(占43.6%)。共发现心肌桥104段,其中位于左前降支(LAD)中段的占78.9%(82/104)。104段心肌桥分布在99例患者,心肌桥的检出率是30.4%(99/326),单纯心肌桥36例。生存分析发现,单纯心肌桥与冠状动脉完全正常的患者的生存曲线之间没有差异(P=0.441),而单纯心肌桥的患者的生存曲线与存在斑块的患者的生存曲线之间的差异没有统计学意义(P0.0167),但是两者生存曲线之间有分开的趋势。结论 320排CT冠状动脉造影诊断的单纯心肌桥患者的预后良好。
[Abstract]:Objective to study the prognosis of patients with myocardial bridge diagnosed by 320 slice coronary CT angiography (CCTA). Methods patients undergoing CCTA from August 2008 to December 2010 were divided into three groups: coronary artery complete normal coronary artery plaque group and myocardial bridge group. The endpoint events were cardiogenic death, non-fatal AMI, unstable angina pectoris requiring hospitalization, revascularization therapy due to myocardial ischemia symptoms or objective evidence, and death from other causes. Survival analysis was performed on the results of follow-up. Results the age of 326 patients was (66.6 卤11.8) years old, 184 males (43.6%). A total of 104 segments of myocardial bridge were found, of which 78.9% (82 / 104) were located in the middle segment of left anterior descending branch (lad) .104 segment was distributed in 99 patients. The positive rate of myocardial bridge was 30.4% (99 / 326), and 36 cases were simple myocardial bridge. Survival analysis found that, There was no difference between the survival curve of patients with pure myocardial bridge and that of patients with complete normal coronary artery (P0. 441), but there was no significant difference between the survival curve of patients with myocardial bridge and that of patients with plaque (P0.0167), but there was no significant difference between the survival curve of patients with myocardial bridge and that of patients with plaque (P0. 0167). There is a tendency to separate the two survival curves. Conclusion 320-slice CT coronary angiography is a good prognosis in patients with myocardial bridge.
