【摘要】：目的 :研究单纯前降支心肌桥患者双源CT冠状动脉造影(DSCTCA)与心肌灌注显像(MPI)的相关性。方法 :回顾性分析经DSCTCA诊断为单纯性前降支心肌桥并接受MPI检查的30例患者影像资料;使用Fisher’s精确概率和t检验统计分析心肌桥不同部位、长度、厚度及狭窄率与心肌缺血之间的关系。结果:DSCTCA显示30例单纯性前降支心肌桥患者中,14例MPI为阳性。心肌桥部位对于心肌缺血的影响,差异无统计学意义(P=0.673);长度对于心肌缺血影响,差异无统计学意义(P0.05);而厚度及狭窄率对于心肌缺血影响的差异均有统计学意义(P0.05)。结论 :心肌桥的部位、长度与心肌缺血无明显相关性,而心肌桥的厚度以及狭窄率对于心肌缺血有影响作用。
[Abstract]:Objective: to study the correlation between double source CT coronary angiography (DSCTCA) and myocardial perfusion imaging (MPI) in patients with anterior descending myocardial bridge. Methods: the imaging data of 30 patients with simple anterior descending myocardial bridge diagnosed by DSCTCA and examined by MPI were analyzed retrospectively, and the exact probability and t test of Fisher's were used to analyze the different position and length of myocardial bridge. The relationship between thickness and stenosis rate and myocardial ischemia. Results MPI was positive in 14 of 30 patients with simple anterior descending myocardial bridge. There was no significant difference in the influence of myocardial bridge site on myocardial ischemia, but there was no significant difference in length for myocardial ischemia, and there was no significant difference in thickness and stenosis rate for myocardial ischemia. Conclusion: there is no significant correlation between the location and length of myocardial bridge and myocardial ischemia, but the thickness of myocardial bridge and the rate of stenosis have influence on myocardial ischemia.
