冠脉CTA在评估糖尿病患者冠脉临界病变管腔狭窄程度中的应用价值分析

Analysis of the value of coronary artery CTA in evaluating the degree of coronary artery stenosis in diabetic patients

目的:探讨应用冠脉CT血管造影(CTA)用于诊断糖尿病冠脉临界病变管腔狭窄度的价值。方法:选取2018年1月至2019年5月收治的80例2型糖尿病患者为研究对象,所有患者均经冠状动脉造影(CAG)确诊冠脉临界病变且管腔狭窄,所有的患者均实施CAG、CTA检查,获取的影像均由2名影像科医师阅片,以CAG诊断结果为金标准,狭窄率50%作为判断血管狭窄程度的边界值,分析冠脉CTA在糖尿病患者中的诊断价值。结果:CAG诊断80例患者总计包含127支病变血管,其中包括前降支病变血管63支,左回旋支30例,右冠脉34例;kappa一致性结果显示冠脉CTA与CAG对狭窄程度的判断一致性差异小。结论:应用冠脉CTA对糖尿病患者冠脉临界病变狭窄的诊断价值显著,可准确判定病变狭窄程度,值得推广普及。

Objective:To explore the value of coronary CT angiography(CTA)in the diagnosis of diabetic coronary artery disease with critical lumen stenosis.Methods:80 cases of patients with type 2 diabetes between January 2018 and May 2019 were analyzed as the research objects.All patients received coronary angiography(CAG)and were diagnosed as coronary borderline lesions and luminal stenosis.All patients were implemented with CAG and CTA examination.The images obtained were read by two practitioners,according to the CAG diagnosis as the gold standard,narrow rate 50%as vascular stenosis degree of boundary value,to analyze the coronary CTA diagnostic value in patients with diabetes.Results:The 80 patients with CAG diagnosis included 127 diseased vessels in total,including 63 anterior descending vessels,30 left circumflex vessels and 34 right coronary arteries.Results of kappa consistency showed that there was little difference in the consistency of coronary CTA and CAG in judging the severity of stenosis.Conclusion:The application of coronary artery CTA in the diagnosis of critical coronary artery stenosis in diabetic patients has significant value,and can accurately determine the degree of coronary artery stenosis,which is worth popularizing.
