摘　　要：为分析老年人群行平板运动实验对提高冠心病诊断的意义,收集45例年龄在70岁以上的老年患者行平板运动的数据,根据冠脉造影结果和病变累及血管数目进行分组。分析各组平板运动实验数据与冠心病诊断的关系。结果显示:年龄在70岁以上老年人群中,女性人群行平板运动实验的准确度、阳性预测和阴性预测高于男性;冠心病组的心血管危险因素高于无冠心病组;真阳性组心电图ST段压低幅度大于假阳性组;三支血管病变组危险因素最多,目标心率达标率最低,ST段压低幅度最大(P<0.05)。研究提示, 70岁以上老年患者行平板运动实验多个参数可提高冠心病诊断的准确性。In order to analyze the significance of treadmill exercise test for improving the diagnosis of coronary heart disease in elderly patients, 45 elderly patients(≥70 years old) underwent treadmill exercise data, and were grouped according to coronary angiography results and the number of vessels involved in lesions. The relationship between treadmill exercise test data and coronary heart disease diagnosis was analyzed. The results showed that the accuracy, positive prediction and negative prediction of treadmill exercise test were higher in the elderly female population than in the elderly male population. The cardiovascular risk factors in CHD group are higher than those in non-CHD group. The ST segment depression in true positive group is larger than that in false positive group. The risk factors were the most, the target heart rate reaching the standard rate was the lowest, and the ST-segment depression amplitude was the largest in the three vessel lesion group. This result suggests that the accuracy of coronary heart disease diagnosis can be improved by combining multiple parameters of treadmill exercise test for elderly patients.
