分析冠心病患者进行CTA与超声心动图检查对冠状动脉狭窄程度的评估价值

Analysis of the Assessment Value of CTA and Echocardiography in Evaluating Coronary Artery Stenosis in Coronary Heart Disease Patients

目的对比分析冠心病患者进行CT血管造影(CTA)与超声心动图检查对冠状动脉狭窄程度的评估价值。方法本研究共纳入2022年2月至2024年1月在安阳市第六人民医院接受检查的86例疑似冠心病患者,患者入院后均接受冠状动脉造影、CTA、超声心动图检查,以冠状动脉造影检查为金标准,将不同检查方法及超声心动图、CTA联合检查的结果与冠状动脉狭窄程度的检出率进行比较。结果86例疑似冠心病患者中共发现101支血管病变,其中CTA共检查出狭窄程度>50%的血管病变为76支,占比75.25%,而两种方法联合共检查出狭窄程度>50%的血管病变87支,占比86.14%,联合检查冠状动脉狭窄检出率高于单独CTA检查,但差异无统计学意义(P>0.05);冠状动脉造影检查诊断冠心病患者40例,CTA诊断冠心病患者34例,敏感度、特异度、准确度分别为75.00%(30/40)、91.30%(42/46)、83.72%(72/86);联合检查冠心病患者为36例,敏感度、特异度、准确度分别为82.50%(33/40)、93.48%(43/46)、88.37%(76/86),联合检查冠状动脉狭窄程度检出率Kappa值高于单独采用CTA检查。结论用CTA、超声心动图联合检查冠状动脉狭窄程度准确性较高,可对冠状动脉狭窄导致的冠心病进行评定,具有临床应用价值。

Objective To compare and analyze the assessment value of CT angiography(CTA)and echocardiography in evaluating coronary artery stenosis in patients with coronary heart disease.Methods This study included 86 suspected coronary heart disease patients who underwent examination at the Sixth People's Hospital of Anyang from February 2022 to January 2024.All patients received coronary angiography,CTA,and echocardiography examinations upon admission.Coronary angiography results were used as the gold standard,and the detection rates of different examination methods,as well as the combined use of echocardiography and CTA,were compared for assessing the degree of coronary artery stenosis.Results Among the 86 suspected coronary heart disease patients,101 vascular lesions were detected.CTA identified 76 lesions with stenosis>50%,accounting for 75.25%,while the combined method identified 87 lesions with stenosis>50%,accounting for 86.14%.The detection rate of coronary artery stenosis using the combined method was higher than using CTA alone,but the difference was not statistically significant(P>0.05).Coronary angiography diagnosed 40 cases of coronary heart disease,while CTA diagnosed 34 cases,with sensitivity,specificity,and accuracy of 75.00%(30/40),91.30%(42/46),and 83.72%(72/86),respectively.The combined method diagnosed 36 cases of coronary heart disease,with sensitivity,specificity,and accuracy of 82.50%(33/40),93.48%(43/46),and 88.37%(76/86),respectively.The Kappa value for detecting the degree of coronary artery stenosis was higher using the combined method compared to CTA alone.Conclusion The combined use of CTA and echocardiography has high accuracy in assessing the degree of coronary artery stenosis,making it valuable for evaluating coronary heart disease caused by coronary artery stenosis.
