冠状动脉造影与冠状动脉CT在检测冠状动脉狭窄中的对比分析

Contrastive Analysis of the Coronary Angiography and Coronary CT in the Diagnosis of Coronary Artery Stenosis

目的:评价冠脉造影与冠脉CT在诊断冠状动脉粥样硬化中的准确性。方法:入选63例拟诊冠心病患者,同时行冠脉CT和冠脉造影。结果:共检测378支冠状动脉分支。冠脉造影显示轻度狭窄24支,中度狭窄19支,重度狭窄83支。冠脉CT显示轻度狭窄85支,中度狭窄14支,重度狭窄54支。以冠状动脉造影结果做为标准,冠脉CT检测冠状动脉狭窄的敏感度为88.3%,特异度为28.2%,准确性为53,1%;阳性预测值为46.49%,阴性预测值为77.4%,差异具有统计学意义。结论:冠脉CT检测冠状动脉狭窄的准确率相对偏低。

Objective：To Evaluation the coronary angiography and coronary CT in the diagnosis of coronary atherosclerosis in accuracy. Methods： In 63 patients with coronary heart disease diagnosis fitting, All patients have line coronary CT and coronary artery angiography. Results ：Detected 378 cigarettes coronary artery branch, Among them, the coronary angiography found mild stenosis vascular are 24 branch; 19 vascular is Moderate stenosis;83vascular is severe stenosis. Conclusion： CT testing out 85 vascular is mild stenosis , 14 vascular is Moderate stenosis; 54 vascular is severe stenosis . With coronary artery imaging results as a standard, Coronary CT detection of coronary artery stenosis of the sensitivity was 88, 3%, Specific degree is 28.2%, Accuracy for 53.1% ;Positive predictive value was 46.49 % ; Negative predictive value was 77.4 % ; A statistically significant difference Conclusion： Coronary artery CT detection of coronary artery stenosis relatively low accuracy.
