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。
Poke: [Objective] To compare the diagnostic value of three kinds of routine clinical diagnosis of coronary heart disease: typical symptoms of chest pain, electrocarogram (ECG) and cardiac troponin Tn in patients with coronary heart disease. [Methods] Seventy patients with suspected coronary heart disease were selected and underwent coronary angiography (ECG), cardiac troponin Tn and coronary artery angiography (CAG) within one week after treatment. Seventy patients were divided into two groups (N = 51) and non-coronary heart disease group (n = 19), the detection rate of coronary heart disease and the specificity and accuracy of ECG, cardiac troponin Tn and paroxysmal chest pain were analyzed respectively index. [Results] The sensitivity of chest pain, ECG and cardiac troponin Tn in diagnosis of coronary heart disease were 56.86%, 21.57% and 88.24% respectively; the specificity were 42.11%, 63.16% and 89.47% respectively; the accuracy were 52.86% and 32.86 %, 88.57%. [Conclusion] ECG and cardiac troponin Tn are safe, non-invasive and reproducible methods for the diagnosis of coronary heart disease. If combined with the above three indexes, coronary heart disease will be improved to a great extent The diagnostic accuracy.
