摘　　要：目的:比较单光子发射计算机断层成像(SPECT)心肌灌注显像与冠状动脉CT血管成像(CCTA)对冠状动脉粥样硬化性心脏病心肌缺血(CHD-MI)的诊断价值。方法:纳入2021年1月~2022年9月本院84例疑似CHDMI患者,全部实施SPECT心肌灌注显像检查、CCTA检查。金标准定为冠状动脉造影结果,结合病例数诊断结果与冠状动脉支数诊断结果,对比SPECT心肌灌注显像、CCTA诊断CHD-MI的价值。结果:结合病例数诊断结果,CCTA诊断CHD-MI的准确率为88.10%、灵敏度为96.88%、特异度为60.00%;SPECT心肌灌注显像诊断CHD-MI的准确度为85.71%、灵敏度为84.38%、特异度为90.00%。上述两种诊断方法结合患者例数诊断CHD-MI的准确度、精确度、灵敏度比较,组间差异不显著(P>0.05)。结合冠状动脉支数诊断结果,CTA诊断CHD-MI的准确率为82.54%、灵敏度为93.44%、特异度为73.31%;SPECT心肌灌注显像诊断CHD-MI的准确度为84.92%、灵敏度为78.69%、特异度为90.77%。CCTA结合冠状动脉支数诊断CHD-MI的灵敏度高于SPECT心肌灌注显像,诊断特异度低于SPECT心肌灌注显像,差异显著(P<0.05)。结论:SPECT心肌灌注显像与CCTA对CHD-MI均具有一定的诊断价值,其中,特异度较高的为SPECT心肌灌注显像,灵敏度较高的为CCTA,两种诊断方式各有优势,可互为补充,临床可根据需求选用。Objective: To compare the diagnostic value of single photon emission computed tomography(SPECT) myocardial perfusion imaging and coronary CT angiography(CCTA) for myocardial ischemia(CHD-MI) in coronary heart disease. Methods:84 patients suspected of CHD-MI in our hospital from January 2021 to September 2022 were enrolled, all of whom underwent SPECT myocardial perfusion imaging and CCTA. The gold standard was the result of coronary angiography. The value of myocardial perfusion imaging and CCTA in the diagnosis of CHD-MI was compared by combining the diagnosis results of the number of cases and the number of coronary arteries. Results: Combined with the number of cases, the accuracy, sensitivity and specificity of CCTA in the diagnosis of CHD-MI were 88.10%, 96.88% and 60.00%. The accuracy, sensitivity and specificity of SPECT myocardial perfusion imaging for the diagnosis of CHD-MI were 85.71%, 84.38% and 90.00%. The accuracy, accuracy and sensitivity of the above two diagnostic methods combined with the number of patients in the diagnosis of CHD-MI showed no significant difference between groups(P>0.05). Combined with the results of coronary artery number diagnosis, the accuracy, sensitivity and specificity of CTA in the diagnosis of CHD-MI were 82.54%, 93.44% and 73.31%. The accuracy, sensitivity and specificity of SPECT myocardial perfusion imaging for the diagnosis of CHD-MI were 84.92%, 78.69% and 90.77% respectively. The sensitivity of CCTA combined with the number of coronary artery in the diagnosis of CHD-MI was higher than that of SPECT myocardial perfusion imaging, and the diagnostic specificity was lower than that of SPECT myocardial perfusion imaging, the difference was significant(P<0.05). Conclusion: SPECT myocardial perfusion imaging and coronary CCTA both have certain diagnostic value for CHD-MI, among which SPECT myocardial perfusion imaging with higher specificity and CCTA with higher sensitivity. The two diagnostic methods have their own advantages and can complement each other. Clinical can
