背景：极量运动试验时心电图异常是无症状冠心病患者未来冠心病死亡率的强预测因子。
Background - : An abnormal ECG during maximal exercise testing has been shown to be a powerful predictor of future coronary heart disease (CHD) mortality in asymptomatic men.
结论：COPD患者极量运动后气体交换参数恢复半衰期较正常人明显延长，常规剂量氨茶碱对此无明显影响。
Conclusions:Recovery half life of gas exchange in COPD is significantly longer than in the normal individuals and is not influenced by aminophylline in common dosage.
GSH含量和GSH- PX活性亚极量负荷后显著降低（P< 0.001）， 力竭性运动后回升，但仍低于安静时水平。
GSH content and GSH- PX reactivity decreased significantly(P<0.001)during sub- maxiaml load and increased after exhaustive exercise which was still lower that of resting state.
