128层容积CT冠状动脉成像在冠状动脉粥样硬化患者中的应用价值分析

Analysis on Application Value of Coronary Angiography of 128 MDCT in Patients with Coronary Atherosclerosis

目的分析128层容积CT冠状动脉成像在冠状动脉粥样硬化患者中的应用价值。方法回顾分析本院2018年3月至2019年3月收治的60例冠状动脉粥样硬化患者的临床资料。根据影像学资料总结128层容积CT检查所得结果进行分析诊断;分析冠状动脉粥样硬化的CT图像表现,记录患者平扫和增强后的相关数据。以CAG诊断冠状动脉狭窄程度的范围为参考标准,评估128层容积CT诊断冠状动脉狭窄的符合。结果本组60例患者中,共计240支血管,128层容积CT发现130支冠状动脉狭窄,其中LAD60支、LCX18支、LMA11支、RCA41支;与CAG结果符合的有121支,其中LAD58支、LCX16支、LMA9支、RCA39支(P>0.05)。经128容积CT检查冠状动脉轻度狭窄有21支,诊断敏感性和特异性分别为76.60%、85.71%;中度狭窄有29支,诊断敏感性和特异性分别为89.66%、93.10%;重度狭窄有33支,诊断敏感性和特异性分别为90.91%、96.97%;完全闭塞的有47支,诊断敏感性和特异性分别为95.74%、97.87%(P<0.05)。结论128容积CT冠状动脉成像检查对冠状动脉粥样硬化的诊断具有重要的价值,临床上可对该检查的影像学特征进行全面分析,结合患者表现出的临床特征对冠状动脉粥样硬化进行诊断和治疗.

Objective To analyze the application value of coronary angiography of 128 MDCT in patients with coronary atherosclerosis. Methods The clinical data of 60 patients with coronary atherosclerosis admitted to our hospital from March 2018 to March 2019 were retrospectively analyzed. According to the imaging data, the results obtained from 128 MDCT examination were analyzed and diagnosed. The CT images of coronary atherosclerosis were analyzed, and the data of patients after plain and enhanced scan were recorded. The range of coronary artery stenosis diagnosed by CAG was used as a reference to evaluate the coincidence rate of coronary artery stenosis diagnosed by 128 MDCT. Results In this group of 60 patients, there were 240 vessels in total, and 130 vessels with coronary stenosis were found by 128 MDCT, including 60 LADs, 18 LCXs, 11 LMAs, and 41 RCAs. There were 121 vessels which were was consistent with results of CAG, including 58 LADs, 16 LCXs, 9 LMAs, and 39 RCAs(P>0.05). There were 21 vessels diagnosed as mild coronary stenosis by 128 MDCT and the diagnostic sensitivity and specificity were 76.60% and 85.71%, respectively. There were 29 vessels diagnosed as moderate coronary stenosis by 128 MDCT and the diagnostic sensitivity and specificity were 89.66% and 93.10%, respectively. There were 33 vessels diagnosed as severe coronary stenosis by 128 MDCT and the diagnostic sensitivity and specificity were 90.91% and 96.97%, respectively. There were 47 vessel diagnosed with complete occlusion, and the diagnostic sensitivity and specificity were 95.74% and 97.87%, respectively(P<0.05). Conclusion The coronary angiography of 128 MDCT is of great value in the diagnosis of coronary atherosclerosis. In clinic, the imaging features of the examination can be comprehensively analyzed, and the clinical features of the patient can be combined to diagnose and treat coronary atherosclerosis.
