多巴酚丁胺负荷心电图试验对冠心病的临床诊断价值

The clinical value of test about dobutamine stress of ECG for CHD.

对60例可疑冠心病者进行多巴酚丁胺负荷心电图试验,以冠状动脉造影为标准评价该试验对冠心病的诊断价值。判定标准以J点后0.08秒ST段偏移0.1mV以上为阳性,诊断冠心病的敏感性,特异性、准确度分别为75.7%,78.7%和76.6%。对冠脉单支、双支和三支病变诊断的敏感性分别为52.6%、100%和100%。试验中未发现明显的不良反应,显示本试验是一种安全可行、准确性较好的诊断冠心病的无创检查方法,并可在基层医院推广应用。

cases of suspicious coronary heart disease were carried on dobutamine electrocardiogram stress test. The diagnostic value of this test was evaluated by comparing with the results of coronary arteriography. When the excursion of ST segment at 0.08 seconds after J point is over 0.1mV, it is judged as positive. The sensitivity,specificity and accuracy of the test were 75.7%,78.7% and 76.6% respectively. The sensitivity of this test to diagnose the pathologic changes of coronary artery for single branch, double branch and triple branch were 52.6%,100% and 100%.No obvious adverse effect was observed during the test.It concluded that this test is a safe,feasible and nicety harmeless method to diognose coronary heart disease,and can be applicated extensively. ingrass-roots hospitals.
