CT冠脉血管成像在冠心病心绞痛临床诊断中的应用观察

目的探讨CT冠脉血管成像(CTA)对冠心病心绞痛的临床诊断价值。 方法回顾性分析2016年1月至2017年7月单县海吉亚医院心血管内科收治的100例疑似冠心病心绞痛患者的病例资料，所有患者均接受CTA及冠状动脉造影(CAG)检查，以CAG为参照评价CTA对冠心病心绞痛的诊断价值。 结果CTA、CAG对不同冠脉血管分支检出率相比，差异无统计学意义(P>0.05)；CTA诊断灵敏度为90.51%(124/137)，特异度为93.16%(245/263)，准确度为92.25%(369/400)。 结论CTA在冠心病心绞痛诊断中可与CAG保持高度一致性，但CTA具有操作便捷、无创等优势，可作为临床筛查疑似心绞痛患者的一种有效手段。

Application of CT angicaphy in clinical diagnosis of coronary heart disease and angina pectoris

ObjectiveTo investigate the value of computerized tomography angiography (CTA) in clinical diagnosis of coronary heart disease and angina pectoris. MethodsThe clinical data of 100 patients with suspected coronary heart disease and angina pectoris in the cardiovascular medicine department from January of 2016 to July of 2017 were retrospectively analyzed. All the patients were given CTA and coronary angiography (CAG) examination. The CAG results were taken as the reference, the clinical effects of CTA in the diagnosis of coronary heart disease and angina pectoris were assessed. ResultsThere was no statisticcal difference in the detection rate of different branches of coronary vessels by CTA and CAG (P>0.05). The diagnostic sensitivity, specificity and accuracy of CTA were 90.51% (124/137), 93.16% (245/263), 92.25% (369/400). ConclusionCTA has high consistency with CAG in the diagnosis of coronary heart disease and angina pectoris, but CTA has the advantages of convenient operation and non-invasiveness, and it can be used as an effective means for clinical screening of patients with suspected angina pectoris.
