摘　　要：目的分析320排CT评估重度冠状动脉狭窄患者的静息态下心肌灌注改变。方法选取我院临床疑诊的200例冠心病患者,将其分为冠状动脉前降支(LAD)、右冠状动脉(RCA)组,按照冠状动脉狭窄程度分为4个亚组,比较各节段透壁心肌灌注指数(TPR)。结果重度狭窄组患者在LAD、RCA支配节段TPR指数,与正常组比较,差异具有统计学意义(P<0.05);中度狭窄患者TPR指数仅在LAD支配节段出现病变时,与正常组比较,差异具有统计学意义(P<0.05)。结论 CT检查可有效评估重度冠状动脉狭窄患者静息态心肌灌注情况。Objective To analyze the changes of myocardial perfusion in the resting state of patients with severe coronary artery stenosis by 320 rows of CT.Methods 200 cases of patients with coronary heart disease in our hospital were divided into the anterior descending coronary artery(LAD)group,right coronary artery(RCA)group,according to the degree of coronary artery stenosis were divided into 4 subgroups,each segmental transmural myocardial perfusion index(TPR).Results The TPR index of LAD and RCA innervation segment in severe stenosis group was significantly different from that in normal group(P<0.05).In patients with moderate stenosis,the TPR index was only in the LAD dominant segment,and the difference was statistically significant compared with the normal group(P<0.05).Conclusion CT examination can effectively evaluate the resting state myocardial perfusion in patients with severe coronary stenosis.
