| Objective To explore the effects of different intensities of exercise rehabilitation on elderly patients with coronary heart disease. Methods A total of 90 elderly patients with coronary artery disease admitted to the First Affiliated Hospital of Anhui Medical University from Aug 2016 to Sept 2017 were selected as study subjects and divided into three groups using a completely randomized method. The control group (n=30) was only given the routine drug treatment. The low (n=30) or moderate (n=30) intensity exercise rehabilitation group (n=30) received low strength or moderate rehabilitation exercise respectively in addition to the above regular treatment. All patients were treated for six months. After the treatment, we evaluated left ventricular ejection fraction (LVEF) and left ventricular end diastolic diameter (LVEDD) through cardiac ultrasonography and performed serological examinations (total cholesterol, three acyl glycerol, low density lipoprotein). Results 1). Compared to control group, six months treatment did not alter LVEF and LVEDD in low exercise group (t=-1.000,-1.000, P>0.05). However, both LVEF and LVEDD were markedly improved in moderate exercise intensity group (t=-11.0 00, 6.500, P<0.05). 2). In all groups, the blood lipid indexes (total cholesterol, three acyl glycerol, low density lipoprotein) were improved after six months' treatment, with greater improvement in exercise groups (P<0.05). In addition, the blood lipid indexes were improved greater in moderate intensity exercise group when compared to low intensity movement group (P<0.05). Conclusion Regular drug treatment combined with moderate intensity exercise rehabilitation therapy significantly improves blood lipid and heart function in elder coronary heart patients. |
