摘　　要：目的分析多层螺旋CT(MSCT)评估老年人群冠心病冠状动脉狭窄程度的准确性。方法选取本院2016年4月至2020年3月收治的76例冠心病患者作为研究对象。以CAG为“金标准”,MSCT评估冠心病冠状动脉狭窄程度准确性。结果76例患者,共278支血管,经CAG检查显示共144支冠状动脉狭窄;经MSCT发现155支冠状动脉狭窄(LAD 25支、LCX17支、LMA 68支、RCA 45支),其中有11支病变血管诊断与CAG不符,MSCT诊断符合率为92.90%,与CAG比较无差异(P>0.05);144支冠状动脉狭窄经CAG诊断轻度狭窄23支,中度狭窄89支,重度狭窄32支。经MSCT诊断轻度狭窄21支,诊断准确率为91.30%;中度狭窄87支,诊断准确率为97.75%;重度狭窄31支,诊断准确率为96.88%。结论MSCT在评估冠心病冠状动脉狭窄程度上具有较高的准确性,安全可靠、经济方便,可作为筛查冠心病的一种无创方法,对于预测及早期诊断冠心病具有重要作用。Objective To analyze the accuracy of multi-slice spiral CT(MSCT)to assess the severity of coronary artery stenosis in the elderly.Methods 76 patients with coronary heart disease admitted to our hospital from April 2016 to March 2020 were selected as the research object.CAG was used as the gold standard,and the accuracy of MSCT to assess the severity of coronary artery stenosis was calculated.Results There were 278 vessels in 76 patients.CAG examination showed in total 144 vessels with coronary artery stenosis.MSCT found 155 vessels with coronary artery stenosis(25 LAD,17 LCX,68 LMA,45 RCA).Among them,the diagnosis of 11 diseased vessels was inconsistent with CAG.The diagnostic accuracy of MSCT was 92.90%,and the difference from CAG was not statistically significant(P>0.05).In the 144 vessels with coronary artery stenosis,23 were diagnosed with mild stenosis,89 were diagnosed with moderate stenosis,and 32 were diagnosed with severe stenosis by CAG.And 21 were diagnosed with mild stenosis by MSCT,diagnostic accuracy was 91.30%,87 were diagnosed with moderate stenosis,diagnostic accuracy was 97.75%,and 31 were diagnosed with severe stenosis,diagnostic accuracy was 96.88%.Conclusion MSCT has high accuracy in assessing the severity of coronary artery stenosis in coronary heart disease.It is safe,reliable,economical and convenient.It can be used as a noninvasive method for screening coronary heart disease,and play an important role in predicting and early diagnosis of coronary heart disease.
