45例老年人活动平板运动试验的临床研究及安全性评价

45 cases of treadmill exercise testing in elderly clinical study

目的利用活动平板试验探讨老年人与冠心病发生率的关系及临床价值。方法分析45例老年人活动平板运动试验就诊者,应用Bruce方案进行次级量平板运动试验。结果平板运动试验的结果与冠状动脉造影符合率较高。结果无显著差异。平板运动试验检测灵敏度为89.13%,假阳性率为5.36%,特异度94.28%,假阴性率11.54%,阳性预测值94.64%。左冠状动脉、多支、右冠状动脉出现多导联段压低,左冠状动脉前降支检出率高。结论老年人活动平板运动试验有利于筛查出不典型或隐匿型冠心病患者,作为一种简便,无创且准确性较高的检查方法,具有推广价值,本研究说明年龄并非影响该项检查的关键因素,建议在运动试验中不设置年龄限制。

Objective To explore the use of treadmill exercise test the elderly and the relationship be- tween the incidence of coronary heart disease and its clinical value. Methods 45 cases of elderly attenders treadmill exercise test, the application program sub-volume of Bruce treadmill exercise test. Results The re- suits of treadmill exercise test and coronary angiography in line with a higher rate. Results No significant differ- ence. Treadmill exercise test for detection sensitivity was 100%, false positive rate was 0%, a specificity of 88.46%, false-negative rate of 11.54%, positive predictive value of 86. 36%. The left coronary artery, multi- ple branches, there is more than the right coronary artery segment depression in leads, the left anterior descend- ing coronary artery detection rate. Conclusion The elderly treadmill exercise test is not conducive to screening out the typical or occult coronary heart disease patients, as a simple, non-invasive inspection methods and high accuracy, with promotion of value. This study shows that age is not a key factor in affecting the check, it is rec- ommended not to set in motion the age limit for testing.
