Effect of exercise prescription to life quality in patients' after coronary artery bypass grafting

Abstract

Objective To discuss the effects of exercise prescription on the patients' life quality underwent coronary artery bypass grafting.Methods 105 patients involved in via convenience sampling were divided into experimental group(n=61) and control group(n=44), control group received rehabilitation exercise routinely, experimental group followed targeted exercise prescription and primary nurse instructed them in exercise. To compare and analyze the indexes of two groups before and after operation.Results There were no differences in all the indexes between the two groups at discharge time(P>0.05). One month after discharge, basic heart rate and blood pressure in exercise group were lower than those in control group, there was no statistical difference(P>0.05). Compared with control group, basic heart rate decreased significantly in exercise group three months after discharge[(79.76±7.41) vs (82.41±7.25),t=-2.1689,P<0.05], and blood pressure decreased significantly in exercise group three months after discharge, and oxygen pressure increased significantly(P<0.05), which were even better at six months after discharge. Meanwhile, max exercise respiratory rate decreased in exercise group [(33.22±2.72) vs (37.56±3.52),t=-6.631,P<0.01].Conclusions Exercise prescription can be effective in improving patient's rehabilitation condition after coronary artery bypass grafting, effectively increase the patient's exercise tolerance and life quality.
