【摘要】 目的 :对冠心病患者和年龄相当的正常健康人进行运动前、后的运动耐量连续测定并探讨其临床意义。方法 :应用 Bruce方案在 Quest型活动平板运动仪上进行次极量或症状限制性平板运动试验。结果 :(1)两组在运动的前 3分钟内运动耐量相差不显著 ;(2 )实验组最大运动耐量 (7.0 1± 0 .11METs)明显低于对照组的 (13.6±0 .14METs) ,P<0 .0 5 ;(3)多支冠脉病变者运动耐量 <6 .5 METs。结论 :随着病情加重 ,冠心病患者运动耐量下降 ,运动耐量低于 6 .5 METs时 ,可能有多支冠脉病变更多还原

【Abstract】 Objective:To evaluate the significance of exercise tolerance in patients with coronary heart disease(CHD) before and after exercise.Methods:Values of exercise tolerance were detected by treadmill exercise ECG test.Results:Exercise tolerance of two groups was similar in exercise before 3 min,then it of CHD decreased significantly( P <0 05).Conclusion:Along with patient’s condition progressing exercise tolerance of patients with CHD decrease;that suggests there are multiple coronary diseases when exercise tolerance is less than 6 5METs.更多还原
