摘　　要：目的探讨冠脉CT血管造影(CTA)与有创血管造影在冠脉临界病变血管狭窄诊断中的应用价值分析。方法选取2020年10月—2021年10月在该院接受治疗的冠脉临界病变血管狭窄患者107例,所有患者均接受冠脉CTA与有创血管造影诊断。记录两种诊断方式的临界病变血管病理参数,并以有创血管造影诊断结果为金标准,分析冠脉CTA的诊断敏感度及特异度。结果两种诊断方式的临界病变血管病理参数对比,差异无统计学意义(P>0.05);有创血管造影诊断结果显示,107例患者中,有98例患者存在冠脉临界病变血管狭窄,共有166支冠脉血管涉及临界病变,其中有24例患者为双支病变,有21例患者为三支病变;CTA诊断结果显示,107例患者中,有94例患者存在冠脉临界病变血管狭窄。与有创血管造影诊断结果对比,CTA诊断结果显示,107例患者中,有94例患者存在冠脉临界病变血管狭窄;与有创血管造影诊断结果对比,CTA诊断准确度为92.52%(99/107),特异度为55.56%(5/9),敏感度为95.92%(94/98)。两种诊断结果准确度、特异度与敏感度对比,差异无统计学意义(χ^(2)=0.003、0.016、0.002,P>0.05)。结论CTA与有创血管造影在冠脉临界病变血管狭窄诊断中具有较为接近的特异度及敏感度,且该诊断方式安全度较高、价格低廉,故具有较高的临床应用价值。Objective To analyze the application value of coronary CT angiography(CTA)and invasive angiography in the diagno⁃sis of coronary critical disease vascular stenosis.Methods 107 patients with critical coronary stenosis treated in the hospital from October 2020 to October 2021 were selected.All patients were diagnosed by coronary CTA and invasive angiography.The critical pathological parameters of the two diagnostic methods were recorded.Taking the diagnostic results of invasive angiogra⁃phy as the gold standard,the diagnostic sensitivity and specificity of coronary CTA were analyzed.Results The critical patho⁃logical parameters of the two diagnostic methods were compared,and the difference was not statistically significant(t=0.044,P>0.05);the results of invasive angiography showed that 98 of 107 patients had critical coronary stenosis,and a total of 166 coro⁃nary vessels were involved in critical lesions,including 24 patients with double vessel lesions and 21 patients with three vessel lesions;the diagnostic results of CTA were that 94 of 107 patients had coronary critical lesion vascular stenosis.Compared with the diagnostic results of invasive angiography,the diagnostic accuracy of CTA was 92.52%(99/107),the specificity was 55.56%(5/9),and the sensitivity was 95.92%(94/98).Comparison of accuracy,specificity and sensitivity of two diagnostic results,the difference was not statistically significant(χ^(2)=0.003,0.016,0.002,P>0.05).Conclusion CTA and invasive angiography have simi⁃lar specificity and sensitivity in the diagnosis of coronary artery stenosis,and this diagnostic method has high safety and low price,so it has high clinical value.
