摘　　要：目的探讨冠状动脉CT血管成像诊断冠心病的临床价值。方法选取2018年4月~2019年11月广东省人民医院珠海医院(珠海市金湾中心医院)行冠状动脉造影与冠状动脉CT血管成像检查的56例疑似冠心病患者作为研究对象。比较两种检查方式检测阳性结果、诊断冠脉狭窄、检测结果情况,观察两种检查方式敏感度、特异度、阳性预测值、阴性预测值情况。结果冠状动脉CT血管成像阳性结果为105支,冠状动脉造影阳性结果为95支,阳性吻合率为87.3%(83/95)。冠状动脉CT血管成像狭窄2级吻合率为55.6%(5/9),3级吻合率为88.9%(32/36),4级吻合率为91.3%(42/46),5级吻合率为100.0%(4/4)。以冠状动脉造影结果为100%标准,两种检查方式敏感度、特异度、阳性预测值比较,差异有统计学意义(P<0.05);两种检查方式阴性预测值比较,差异无统计学意义(P>0.05)。结论冠状动脉造影与冠状动脉CT血管成像诊断冠心病无明显差异,且重复性较好,可以作为冠心病筛查的重要方法,具有一定的临床价值。Objective To explore the clinical value of coronary heart disease diagnosed by coronary CT angiography.Methods A total of 56 patients suspected with coronary heart disease who underwent coronary artery angiography and coronary CT angiography in Guangdong Provincial People′s Hospital Zhuhai Hospital(Zhuhai Golden Bay Central Hospital)from April 2018 to November 2019 were selected as the research subjects.The positive results,the diagnosis of coronary stenosis and the results of the two methods were compared,and the sensitivity,specificity,positive predictive value and negative predictive value were observed.Results The tested positive of coronary CT angiography were 105 counts,tested positive of coronary artery angiography were 95 counts,anastomosis positive rate was 87.3%(83/95),two grade stricture coincidence rate of coronary CT angiography was 55.6%(5/9),three grade stricture coincidence rate was 88.9%(32/36),four grade stricture coincidence rate was 91.3%(42/46),five grade stricture coincidence rate was 100.0%(4/4).Coronary angiography result was 100%standard,sensitivity,specificity,positive predictive value of two inspection modes were compared,the differences were statistically significant(P<0.05).There was no significant difference in negative predictive value of two inspection modes(P>0.05).Conclusion The diagnosis coronary heart disease by coronary artery angiography and coronary CT angiography have no obviously difference,repeatability is good,which could be important method of coronary heart disease screening,it has certain clinical value.
