摘要
目的探讨平板运动试验阳性ST段恢复时间与冠状动脉造影结果的关系，分析其临床意义。方法126例平板运动试验阳性患者，均在平板运动试验检查后2周内完成冠状动脉造影术，分析平板运动试验ST段恢复时间与冠状动脉造影结果的关系。结果126例患者中，86例（68．2％）冠状动脉造影阳性，40例（31．8％）冠状动脉造影阴性，假阳性率为31．8％；40例造影阴性患者中，男性15例，假阳性率20．8％，女性25例，假阳性率46．3％，女性患者假阳性率明显高于男性。全部患者ST段恢复平均时间（3．76±2．56）分钟，最短为0分钟（即刻恢复），最长为12分钟，大部分集中在〉1～6分钟之间；恢复时间越长，冠状动脉造影的阳性率越高，恢复时间0～1分钟组，造影阳性率为21．4％，恢复时间〉i～6分钟组为78．4％，恢复时间〉6分钟组达9i．7％；同时，ST段恢复时间0～i分钟组均为单支病变，恢复时间6分钟以上组，双支以上病变达63．6％。结论平板运动试验阳性ST段恢复时间，与冠状动脉造影结果相关，ST段恢复时间在i分钟内，造影阳性率低，病变支数少，恢复时间在1分钟以上，造影的阳性率显著增高。
Objective To investigate the relationship between ST segment recovery time for exercise treadmill test positive and the coronary angiography results and analyze its clinical significance. Methods The study enrolled 126 patients with exercise treadmill test positive,all in 2 weeks completed coronary angiography,analysis was made on the relationship of exercise treadmill test ST segment recovery time and coronary angiography results. Results In all 126 cases,86 cases of coronary angiography positive（68.2%）,40 cases negative（31.8%）,false positive rate was 31.8%; Among the 40 negative cases, 15 cases were male, false positive rate was 20.8 %, 25 cases were female, false positive rate was 46.3 %, women with false positive rate was significantly higher than men. In all patients, ST segment recovery time average was （3. 76±2.56） minutes,the shortest was 0 minute （immediate recovery） ,the longest was 12 minutes, mostly were between % 1-6 minutes. The longer the recovery time, the higher positive rate of angiography, the group of recovery time 0-1 minutes, positive rate was 21.4%, %〉 1 6 minutes group was 78.4% and recovery time above 6 minutes group was 91.7 % ;meanwhile,in the group of 0-1 minutes, all positive cases were single lesion, the group of the recovery time above 6 minutes, the proportion of more than double lesion was 63.6%. Conclusion Exercise treadmill test positive for ST segment recovery time, associated with the coronary angiography, and ST segment recovery time within 1 minute,angiography positive rate is low,less lesion counts,recovery time in more than 1 minute, positive rate was significantly higher.
