腺苷负荷心肌声学造影对冠心病稳定型心绞痛的诊断价值

Diagnostic Value of Adenosine Stress Myocardial Contrast Echocardiography for Stable Angina Pectoris of Coronary Heart Disease

目的探讨腺苷负荷心肌声学造影(MCE)对冠心病稳定型心绞痛的诊断价值。方法选取2020年2月至2021年9月陕西省人民医院心内科收治的疑似冠心病稳定型心绞痛患者424例。以冠状动脉造影为“金标准”,计算经胸超声心动图(TTE)检查、腺苷负荷MCE诊断冠心病稳定型心绞痛的灵敏度、特异度、正确率。结果冠状动脉造影结果显示,阳性304例,阴性120例。TTE检查结果显示,阳性128例,阴性296例。腺苷负荷MCE结果显示,阳性200例,阴性224例。TTE诊断冠心病稳定型心绞痛的灵敏度、特异度以及正确率分别为23.7%、53.3%、32.1%,腺苷负荷MCE诊断冠心病稳定型心绞痛的灵敏度、特异度以及正确率分别为55.3%、73.3%、61.0%。结论腺苷负荷MCE对冠心病稳定型心绞痛有一定诊断价值,值得临床进一步推广和应用。

Objective To explore the diagnostic value of adenosine stress myocardial contrast echocardiography(MCE)for stable angina pectoris of coronary heart disease.Methods A total of 424 patients with suspected stable angina pectoris of coronary heart disease treated in the Department of Cardiology of Shaanxi Provincial People's Hospital from February 2020 to September 2021 were selected.Taking coronary angiography as the"gold standard",the sensitivity,specificity and accuracy rate of transthoracic echocardiography(TTE)examination and adenosine stress MCE in the diagnosis of stable angina pectoris were calculated.Results The coronary angiography results showed that there were 304 positive patients and 120 negative patients.TTE examination results showed that there were 128 positive cases and 296 negative cases.The results of adenosine stress MCE showed that there were 200 positive patients and 224 negative patients.The sensitivity,specificity and accuracy rate of TTE examination in the diagnosis of stable angina pectoris of coronary heart disease were 23.7%,53.3%,and 32.1%,respectively.The sensitivity,specificity and accuracy rate of adenosine stress MCE in the diagnosis of stable angina pectoris of coronary heart disease were 55.3%,73.3%,and 61.0%,respectively.Conclusion Adenosine stress MCE has certain diagnostic value for stable angina pectoris of coronary heart disease,and it is worthy of further clinical promotion and application.
