Objective To analyze the relevant data of cardiopulmonary exercise testing(CPET)in patients with coronary heart disease,and explore the clinical features of CPET.Methods The present study was a retrospective study of 103 patients with coro-nary artery disease who were followed up from May 2021 to August 2023 in the outpatient clinic of the Department of Integrative Car-diology of China-Japan Friendship Hospital.The patients were divided into the under 60 years old group(n =37)and the aged 60 and above group(n =66)according to age;the aged 60 and above was divided into male group(n =37)and female group(n =29)accord-ing to gender;patients were all subjected to CPET test,and the characteristics of CPET indexes were compared among male group of different ages and different gender groups of the same age,and the correlation between gender,age,and CPET indexes was analysed by using the correlation analysis method of Spearman or Pearson.Correlation analysis was used to analyse the correlation between gender,age and CPET test indexes.Results Maximum heart rate(MHR),peak oxygen uptake(VO2peak),peak oxygen pulse(peak O2 pulse),carbon dioxide equivalents(EQCO2),and metabolic equivalents(METs)were lower in the aged 60 and above male group than in the under 60 years old male group,and the differences were statistically significant(P<0.05);The anaerobic subthreshold oxygen uptake(VO2 AT),VO2 peak,peak O2pulse,and METs were lower in the aged 60 and above female group than in the aged 60 and above male group,and the differences were all statistically significant(P<0.05).Spearman or Pearson correlation results showed a correlation between sex and gender and the cardiopulmonary exercise test indices MHR,VO2 AT,VO2peak,peak O2 pulse,and METs.Conclusion The results of CPET in patients with coronary heart disease of different ages and genders are different.Age is negatively correlated with the results of cardiopulmonary function in patients with coronary heart disease;the exercise tolerance of female patients is significantly lower than that of males of the same age,Clinical attention should be paid to rehabilitation intervention in time to improve cardiopulmonary tolerance.
