Abstract：Objective To discuss the influence of 12-week exercise rehabilitation on exercise endurance and heart function in patients with coronary heart disease(CHD).Methods CHD patients(n=100)were chosen from Beijing Rehabilitation Hospital affiliated to Capital Medical University from June 2020 to June 2022,and divided randomly into observation group and control group(each n=50).The control group was given routine rehabilitation training,and observation group was given exercise rehabilitation training for 12 weeks.The changes of 6-minute walk distance(6MWD),peak ventilation rate(PVR),peak oxygen consumption(VO2 peak),the ratio of peak value of mitral valve flow spectrum E in early diastole to peak value of maximum mitral ring movement E'in early diastole(E/E'),the ratio of peak value of mitral valve flow spectrum E in early diastole to peak value of mitral valve flow spectrum A in late diastole(E/A),left ventricular end-diastolic diameter(LVEDD),left ventricular end-systolic diameter(LVESD)and left ventricular ejection fraction(LVEF)were compared between 2 groups before and after training.The adverse events were recorded during training period.Results The levels of 6MWD,PVR,VO2 peak and E/E'were significantly higher,and E/A level was significantly lower in observation group than those in control group after training(P<0.05).The levels of LVEDD and LVESD were significantly lower,and LVEF level was significantly higher in observation group than those in control group after training(P<0.05).The incidence rates of adverse events were significantly lower in observation group than those in control group(P<0.05).Conclusion The exercise rehabilitation for 12 weeks can improve exercise endurance and heart function in CHD patients.
