摘　　要：目的:观察腺苷负荷CT心肌灌注扫描、24h动态心电图联合检查在冠心病心肌缺血诊断中的效能。方法:选取2020年12月至2022年12月该院收治的80例疑似冠心病心肌缺血患者进行前瞻性研究,所有患者均接受24h动态心电图和腺苷负荷CT心肌灌注扫描检查,以核素心肌灌注显像检查诊断结果为金标准,比较腺苷负荷CT心肌灌注扫描、24h动态心电图单项及联合检查诊断冠心病心肌缺血的效能。结果:核素心肌灌注显像检查结果显示,阳性52例,阴性28例。24h动态心电图检查结果显示,阳性46例,阴性34例;腺苷负荷CT心肌灌注扫描检查结果显示,阳性46例,阴性34例;联合检查结果显示,阳性51例,阴性29例。腺苷负荷CT心肌灌注扫描、24h动态心电图联合检查诊断冠心病心肌缺血的灵敏度、特异度、准确度、阳性预测值、阴性预测值均高于二者单项检查,差异有统计学意义(P<0.05)。结论:腺苷负荷CT心肌灌注扫描、24h动态心电图联合检查诊断冠心病心肌缺血的效能高于二者单项检查。Objective:To observe efficiency of adenosine stress CT myocardial perfusion scan and 24 h dynamic electrocardiogram in diagnosis of myocardial ischemia of coronary heart disease.Methods:A prospective study was conducted on 80 patients with suspected myocardial ischemia of coronary heart disease admitted to the hospital from December 2020 to December 2022.All patients underwent 24 h ambulatory electrocardiogram and adenosine stress CT myocardial perfusion scan.Using the diagnostic results of nuclide myocardial perfusion imaging as the gold standard,the efficiencies of adenosine stress CT myocardial perfusion scan,24 h dynamic electrocardiogram single and combined examination in the diagnosis of myocardial ischemia of coronary heart disease were compared.Results:The nuclide myocardial perfusion imaging showed that 52 cases were positive and 28 cases were negative.The 24 h dynamic electrocardiogram showed that 46 cases were positive and 34 cases were negative.The adenosine stress CT myocardial perfusion scan showed that 46 cases were positive and 34 cases were negative.The combined examination showed that 51 cases were positive and 29 cases were negative.The sensitivity,the specificity,the accuracy,the positive predictive value and the negative predictive value of adenosine stress CT myocardial perfusion scan combined with 24 h dynamic electrocardiogram examination in the diagnosis of myocardial ischemia of coronary heart disease were higher than those of the two single examinations,and the differences were statistically significant(P<0.05).Conclusions:The efficiency of adenosine stress CT myocardial perfusion scan combined with 24 h dynamic electrocardiogram examination in the diagnosis of myocardial ischemia of coronary heart disease is higher than that of the two single examinations.
