目的探讨冠状动脉CTA与冠状动脉造影在冠心病临床诊断中的异同。方法选取110例行冠脉CTA检查为阳性的患者,后进行冠脉造影检查,以冠脉造影结果为金标准,比较冠脉CTA在冠心病诊断(冠脉狭窄>50%)上的敏感性、特异性。结果冠脉CTA计算冠脉病变的准确度为97.7%,检查方法无统计学差(P<0.01)。结论冠脉CTA检查可以作为冠心病的诊断工具。
Objective To investigate the similarities and differences between coronary CTA and coronary angiography in the clinical diagnosis of coronary heart disease. Methods One hundred and ten patients with positive coronary CTA were enrolled in this study. Coronary angiography was performed and coronary angiography was used as the gold standard to compare the sensitivity of coronary CTA in the diagnosis of coronary heart disease (coronary artery stenosis> 50%) Specificity. Results The accuracy of coronary CTA in calculating coronary artery disease was 97.7%. There was no significant difference between the two methods (P <0.01). Conclusion Coronary CTA can be used as a diagnostic tool for coronary heart disease.
