Aerobic exercise, cardiac function, heart rate recovery and the quality of life of elderly heart disease patients / 中华物理医学与康复杂志

ABSTRACT

Objective To explore the effect of aerobic exercise on cardiac function,heart rate recovery and the quality of life of elderly heart disease patients.Methods One hundred senile heart disease patients were studied.They were randomly divided into a control group and an observation group,with 50 in each group.Both groups were provided with the conventional anti-platelet aggregation treatment,dilation of blood vessels and control of blood pressure.The observation group was also given individualized aerobic exercise training.At the outset and after 3 months the cardiac function and heart rate recovery of both groups were observed,and their quality of life was evaluated using the SF-36 life quality scale.Results After the treatment,the average left ventricular ejection fraction of those in the observation group was significantly better than before the treatment,and significantly better than the average among the controls.The average 6-minute walking test time and average maximum oxygen uptake in the observation group were also significantly better than before the treatment and significantly better than among the controls.The average peak heart rate and HRR1 in the observation group had increased significantly,and significantly more than those of the control group.The average total SF-36 score in the observation group was also significantly higher.Conclusion Individualized aerobic exercise can significantly improve cardiac function and promote heart rate recovery in elderly patients with heart disease,which is of clinical value for improving their quality of life.
