双源CT冠状动脉CTA在冠心病诊疗中的价值

目的 研究双源CT冠状动脉血管成像(commodity trading advisor, CTA)在冠状动脉粥样硬化性心脏病（以下简称冠心病）诊疗中的诊断价值。方法 选取湖州市第三人民医院和浙北明州医院2019年6月至2022年10月收治的冠心病患者57例作为研究对象，先后进行双源冠状动脉CTA、金标准数字减影血管造影(digital subtraction angiography, DSA)冠状动脉造影检查，对两种检查结果对比分析。结果 双源CTA诊断敏感度为90.63%，准确度为95.18%，特异性为98.48%，阳性预测值为97.75%，阴性预测值为93.53%，两种检查结果差异无统计学意义（P>0.05）。结论 双源冠状动脉CTA在冠状动脉狭窄的诊断中有较高的敏感度、准确度、特异性、阳性预测值、阴性预测值，与DSA冠状动脉造影具有显著的一致性，且无创伤血管成像技术减少许多并发症的产生，操作简单、安全可靠、价格低廉，对冠心病的防治起到指导作用。

The value of coronary CTA based on dual source CT in the diagnosis and treatment of coronary heart disease

Objective To study the value of coronary commodity trading advisor (CTA) based on dual source CT in the diagnosis and treatment of coronary heart disease. Methods Totally 57 patients with coronary heart disease were selected from the Third People''s Hospital of Huzhou City and the Huzhou Ming State Hospital from June 2019 to October 2022, Dual source CTA and digital subtraction angiography (DSA) were performed successively, and the results were compared and analyzed. Results The sensitivity, accuracy, specificity, positive predictive value and negative predictive value of dual source CTA were 90.63%, 95.18%, 98.48%, 97.75% and 93.53%, respectively. There was no significant difference between the two results (P>0.05). Conclusion Dual-source coronary artery has high sensitivity, accuracy, specificity, positive predictive value and negative predictive value in the diagnosis of coronary artery stenosis, which is significantly consistent with gold standard DSA coronary angiography, the technique of non-invasive angiography can reduce the occurrence of many complications, which is simple, safe and reliable, and plays a guiding role in the prevention and treatment of coronary heart disease. Dual-source coronary CTA has high sensitivity and accuracy, and noninvasive angiography can reduce many complications. It is simple, safe, reliable and cheap, it plays a guiding role in the prevention and treatment of coronary heart disease.
