运动疗法在心脏术后康复中的作用

The effect of exercise therapy in the patients after cardiac surgery

目的 :探讨运动疗法在心脏术后康复中的作用。方法 :2 1例心脏手术后患者均接受功率自行车或 /和跑台训练为主的康复训练 ,并采用常规心电运动试验对康复训练前后的各项指标进行比较。结果 :运动训练后 ,运动时间和最大运动负荷显著增加 ,安静时 ,心率、血压 (包括收缩压和舒张压 )、心率 血压乘积均显著下降 (P <0 .0 5 ,P <0 .0 1) ,安静时心电图最大ST段压低明显改善 (P <0 .0 1) ;同等负荷量运动时 ,心率、血压、心率 血压乘积及运动诱发的最大ST段压低与安静状态时有相似的改变 (P <0 .0 5 ,P <0 .0 1)。结论 :心脏术后的康复训练有助于增加体能 ,减轻心肌缺血 ,增加心肌储备功能 。

Objective:To study the effect of exercise therapy in cardiac post operative rehabilitation.Method:21 cases with cardiac surgery received the rehabilitation therapy that mainly consists of bicycle ergometer or/and treadmill exercise.All parameters were compared by routine exercise test before and after training.Result:After exercise training,the duration of exercise and the maximal work load were significantly increased( P <0.01);the heart rate,blood pressure (including SBP and DBP) and rate pressure product (RPP) were significantly decreased ( P<0.05,P< 0.01)in resting state;the resting electrocardiogram showed that the maximal lowered ST segment were improved greatly( P <0.01);with equal exercise stress,the results of the heart rate,blood pressure,RPP and the maximal lowered ST segment led by exercise were similar to that of rest( P<0.05,P< 0.01).Conclusion:The cardiac post operative rehabilitation exercise training could increase physical work capacity and decrease myocardial ischemia. It could also increase cardiac reserve and the quality of life.
