个体化有氧运动对老年冠心病患者心率恢复的影响

Effect of aerobic exercise on heart rate recovery in elderly coronary heart disease patients

目的评价个体化有氧运动对老年冠心病患者心率恢复的影响。方法将60例老年冠心病患者随机分为康复运动组30例和对照组30例。康复运动组进行有氧运动训练3个月,对照组进行日常活动。采用6min步行试验检测2组运动治疗前后的静息心率、峰值心率、心率恢复值、收缩压、舒张压和6min步行距离。结果与治疗前比较,康复运动组治疗3个月峰值心率及心率恢复值明显提高,6min步行距离较运动前明显延长,差异有统计学意义(P<0.05,P<0.01),而血压、静息心率和LVEF比较,差异无统计学意义(P>0.05)。6min步行距离与心率恢复值呈正相关(r=0.48,P<0.01)。结论个体化有氧运动有助于改善老年冠心病患者的心率恢复能力和运动耐量。

Objective To assess the effect of aerobic exercise on heart rate recovery in elderly coro- nary heart disease （CHD） patients. Methods Sixty elderly CHD patients were randomly divided into rehabilitation exercise group （n=30） and control group （n=30）. The patients in rehabilita- tion exercise group had aerobic exercise training for 3 months and those in control group had rou- tine physical activities. Their resting heart rate, peak heart rate, heart rate recovery, SBP, DBP and walking distance were recorded by 6 rain walking testing. Results The peak heart rate and heart rate recovery were significantly higher and the 6 min walking distance was longer in rehabilitation exercise group after exercise than before exercise （P〈0. 05, P〈0. 01）. No significant difference was found in blood pressure,resting heart rate and LVEF （P〉0.05）. The walking distance was positively related with the heart rate recovery （r=0.48,P〈0.01）. Conclusion Aerobic exercise can improve the heart rate recovery and exercise tolerance in elderly CHD patients.
