冠状动脉CTA对患者冠脉狭窄程度、分叉病变的诊断分析研究

Diagnostic Analysis of Coronary CTA in Patients with Coronary Stenosis and Bifurcation Lesions

本研究探讨冠状动脉CT血管成像(CTA)对患者冠脉狭窄程度、分叉病变的诊断价值。选取我院84例接受了CTA检查、冠脉造影(CAG)检查的冠心病患者进行临床研究,对比冠状动脉各个节段及左冠状动脉的CTA、CAG检查结果,以CAG作为诊断金标准,计算CTA对冠脉狭窄、不同狭窄程度的冠脉病变、左冠状动脉分叉病变的诊断价值。CTA诊断冠心病患者冠脉狭窄的灵敏度为89.61%、特异度为91.73%。CTA诊断冠心病患者冠脉狭窄程度与CAG结果的一致性检验结果Kappa值为0.761,P<0.05。经CTA检查诊断冠心病患者出现左冠状动脉分叉病变的灵敏度为86.36%、特异度为90.00%。CTA作为一种无创检查方法,对冠心病患者冠脉狭窄程度、分叉病变具有较高的诊断价值,并且与CAG结果具有较高的一致性。

The study explored the diagnostic value of coronary CT angiography(CTA)in patients with coronary stenosis and bifurcation lesions.A total of 84 patients with coronary heart disease who underwent CTA examination and coronary angiography(CAG)for clinical research.The results of CTA and CAG examinations of each segment of the coronary artery and the left coronary artery were compared.Using CAG as the diagnostic gold standard.The diagnostic value of CTA for coronary artery stenosis,coronary artery disease with different degrees of stenosis,and left coronary artery bifurcation disease were calculated.The sensitivity of CTA in diagnosing coronary artery stenosis in patients with coronary heart disease is 89.61%,and the specificity is 91.73%.The consistency of the degree of coronary artery stenosis in patients with coronary heart disease diagnosed by CTA and the CAG result Kappa value was 0.761,P<0.05.The sensitivity and specificity of left coronary artery bifurcation lesions in patients with coronary heart disease diagnosed by CTA was 86.36%and 90.00%.As a non-invasive examination method,CTA has high diagnostic value for coronary artery stenosis and bifurcation lesions in patients with coronary heart disease,and has high consistency with CAG results.
