【摘要】 捅要:[目的]比较冠心病的3种常规临床诊断方法:典型的胸痛症状、静息心电图(electroc ardiogram,ECG)、心肌肌钙蛋白Tn对冠心病的诊断价值。[方法]选择70例可疑冠心病患者,在就诊后1周内先后接受ECG、心肌肌钙蛋白Tn和冠状动脉造影(coronary arteriongraphy,CAG)检查,以冠状动脉造影为标准,70例患者被分为冠心病组(n=51)和非冠心病组(n=19),分别分析ECG、心肌肌钙蛋白Tn和发作性胸痛对冠心病的检出率及其诊断的特异性、准确性等指标。[结果]胸痛、ECG和心肌肌钙蛋白Tn诊断冠心病的敏感性分别为56.86%、21.57%、88.24%;特异性分别为42.11%、63.16%、89.47%;准确性分别为52.86%、32.86%、88.57%。[结论]ECG、心肌肌钙蛋白Tn是诊断冠心病的安全、无创伤、重复性强且较准确的检查方法,如果将以上3项指标联合运用,将会在很大的程度上提高冠心病的诊断正确率。更多还原

【Abstract】 [Objective] To compare the diagnosis value of three conventional clinical diagnosis methods including thoracalgia, resting electrocardiogram (ECG) and myocardium troponin. [Methods] 70 patients with suspected CHD were collected and diagnosed with resting electrocardiogram, myocardium troponin and CAG tests after the first week of being admitted to hospital. CAG was used as the golden standard, 70 patients were divided into two groups including CHD and non-CHD groups. The detection rate of coronary heart disease by thoracalgia, resting electrocardiogram and myocardium troponin were diagnosed and their specificity and accuracy were also analyzed. [Results] The sensitivities of thoracalgia, resting electrocardiogram and myocardium troponin was 56.86% , 21.57% and 88.24% , respectively; the specificity of them was 42.11% , 63.16% and 89.47%. The accuracy of them was 52.86%, 32.86% and 88.57%. [Conclusion] Resting electrocardiogram and myocardium troponin are the accurate, safe, non-wound and high repeatability diagnosis methods for CHD. If we diagnose the CHD by combining the three methods, the accuracy would be greatly improved.更多还原
