Objective To observe the effect of cardiac exercise rehabilitation program based on cardiopulmonary exercise testing(CPET)on patients with stable coronary heart disease complicated with hypertension.Methods A total of 80 patients with stable coronary artery disease complicated with hypertension in the Xuzhou Central Hospital from February to September 2023 were randomly divided into control group and observation group,with 40 cases in each group.The control group received routine medica-tion for 12 weeks.The observation group received cardiac exercise rehabilitation program based on CPET in addition to the treat-ment of the control group,including aerobic exercise and resistance training,once every other day,3 times a week for 12 weeks.Be-fore and after treatment,CPET was used to evaluate cardiac autonomic function[such as rest heart rate(HRrest),rest systolic blood pressure(SBPrest),rest diastolic blood pressure(DBPrest),peak heart rate(HRpeak),peak systolic blood pressure(SBPpeak),peak diastol-ic blood pressure(DBPpeak),heart rate recovery from the 1st to 6th min(HRRt)].CPET was used to evaluate cardiopulmonary func-tion and exercise ability[peak metabolic equivalent(METspeak),peak work(Workpeak),peak oxygen pulse(VO2/HRpeak),peak oxygen uptake(VO2 peak),anaerobic threshold(AT)and carbon dioxide ventilation equivalents slope(VE/VCO2 slope)].The 36-item short-form health survey(SF-36)was used to evaluate quality of life.Pittsburgh sleep quality index(PSQI)was used to evaluate sleep quality.Results Compared with that before treatment,SBPrest,DBPpeak,HRrest,HRpeak and VE/VCO2 slope in the observation group decreased significantly after treatment,HRR1-HRR6,VO2 peak,AT,VO2/HRpeak,METspeak,Workpeak,SF-36 scores(physical functioning,role physi-cal,bodily pain,general health,social functioning and mental health)increased significantly,PSQI score decreased significantly(P<0.05).Compared with the control group,SBPrest,DBPpeak,HRrest and VE/VCO2 slope in the observation group were significantly lower after treatment,HRR1-HRR4,VO2 peak,AT,VO2/HRpeak,METspeak,Workpeak,SF-36 scores(physical functioning,role physical,bodily pain,general health,social functioning and mental health)were significantly higher after treatment(P<0.05),PSQI score decreased significantly(P<0.05).Conclusion The cardiac exercise rehabilitation program based on CPET can improve cardiac autonomic function,cardiopulmonary function,exercise ability,sleep and quality of life of patients with stable coronary heart disease complicat-ed with hypertension,which is recommended for clinical application.
