冠状动脉CTA对冠脉临界病变管腔狭窄程度的诊断价值

目的探讨冠状动脉CTA对冠脉临界病变管腔狭窄程度的诊断效果。方法选取2016年4月至2018年4月我院收治的冠脉狭窄患者80例,随机分为两组,对照组进行冠状动脉造影(CAG)检查,研究组进行冠状动脉CTA。比较研究组狭窄程度评分、两组检查结果及诊断价值。结果研究组多支病变的右冠状动脉、左回旋支狭窄程度评分高于前降支单支病变(P<0.05),研究组前降支单支病变前降支狭窄程度评分高于多支病变(P<0.05);冠状动脉造影检查与冠状动脉CTA检查一致性的为50%~70%的狭窄共有65段,冠状动脉造影检查判断≤50%的狭窄有2段,冠状动脉CTA检查为5段,冠状动脉CTA检查显影≥70%的有6段;研究组特异度、敏感度、阴性预测值、阳性预测值高于对照组(P<0.05)。结论冠脉临界病变管腔狭窄程度检查中,冠状动脉CTA的诊断结果更准确,应该在临床上广泛推广应用。

Diagnostic Value of Coronary CTA in the Degree of Lumen Stenosis in Critical Coronary Artery Lesions

Objective To investigate the diagnostic effect of coronary CTA on the severity of coronary artery stenosis.Methods 80 patients with coronary artery stenosis in our hospital from April 2016 to April 2018 were selected and randomly divided into two groups.The control group underwent coronary angiography(CAG)and the study group underwent coronary angiography with CT(CTA).The stenosis score,examination results,and diagnostic value of the two groups were compared.Results The stenosis scores of right coronary artery and left circumflex artery in the study group were higher than those in the single-anterior descending artery disease(P<0.05),and the former descending artery stenosis score in the study group was higher than that in the multi vessel disease(P<0.05);the consistency of coronary angiography and coronary CTA examination was 50%~70%in total,there were 65 segments,and the stenosis≤50%was judged by coronary angiography.The specificity,sensitivity,negative predictive value,and positive predictive value of the study group were higher than those of the control group(P<0.05).Conclusion The results of CTA are more accurate in the examination of stenosis degree of coronary critical lesions,which should be widely used in clinical practice.
