摘　　要：目的:探讨冠脉CT血管造影(CCTA)对疑难胸痛患者的诊断价值。方法:对于经过包括心电图、心脏彩超、运动试验、心肌坏死标志物等检查的胸痛筛查流程,仍难以确诊的93例胸痛患者,先后进行64排螺旋CT的CCTA和冠脉造影检查,以明确诊断,了解临床拟诊和CCTA对冠心病诊断的敏感性,特异性和诊断的准确性。结果:以冠脉造影检查对冠心病的诊断为标准,临床拟诊对冠心病诊断的敏感性,特异性和准确性,分别是70.7%(53/75),40.4%(8/18)和84.1%(53/63);CCTA对冠心病诊断的敏感性,特异性和准确性,分别是97.3%(73/75),85.7%(12/14),和92.4%(73/79)。结论:对于疑难胸痛患者的诊断,冠脉CT血管造影有重要价值,又是无创的,可优先采用。Objective： To explore diagnostic value of coronary computed tomography angiography （CCTA） on pa- tients with questionable chest pain. Methods.. The CCTA of 64 row spiral computer tomography and coronary angi- ography （CAG） were executed in order in 93 patients with questionable chest pain undergoing measurements of chest pain screening flow sheet, including ECG, exercise test, echocardiography etc. Results： When the result of CAG diagnosing coronary heart disease （CHD） were regard as standard of diagnosis, the sensitivity, specificity and accuracy of preliminary clinical diagnosis were 70. 7% （53/75）, 40.4% （8/18） and 84.1% （53/63） respectively; the sensitivity, specificity and accuracy of CCTA were 97.3% （73/75）, 85.7% （12/14）, and 92.4% （73/79） re- spectively. Conclusion： The coronary computed tomography angiography possesses important diagnostic value on pa- tients with questionable chest pain, it is atraumatic, so may be preferentially adopted.
