Abstract：【Objective】 To explore the effects of traditional Chinese medicine (TCM) cardiac rehabilitation exercise combined with respiratory function training on oxygenation function, cardiopulmonary function, exercise capacity and quality of life in patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI). 【Methods】 A total of 120 CHD patients after PCI admitted to our hospital from April 2023 to April 2025 were enrolled and randomly divided into the observation group (receiving TCM cardiac rehabilitation exercise combined with respiratory function training) and the control group (receiving respiratory function training alone), with 60 cases in each group. The oxygenation function [maximal oxygen uptake (VO2max), peak rate of perceived exertion (PREspk), peak metabolic equivalent (METspk)], cardiopulmonary function [right ventricular end-diastolic diameter (RVEDD), right ventricular anterior wall thickness (RVAWT), pulmonary artery systolic pressure (PASP), forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), FEV1/FVC], exercise capacity [6-minute walking distance (6MWD), maximal exercise load], and quality of life [Chinese Cardiovascular Quality of Life Questionnaire (CQQC) score] were compared between the two groups. 【Results】 After treatment, VO2max and METspk increased while PREspk decreased in both groups; the observation group had higher VO2max and METspk, and lower PREspk than the control group (all P<0.05). In terms of cardiopulmonary function, RVEDD, RVAWT and PASP decreased, while FEV1, FVC and FEV1/FVC increased in both groups after treatment; the observation group presented lower RVEDD, RVAWT, PASP and higher FEV1, FVC, FEV1/FVC (all P<0.05). Additionally, 6MWD and maximal exercise load of both groups were significantly improved after treatment, with better outcomes in the observation group (P<0.05). All dimension scores of CQQC in the observation group were higher than those in the control group after intervention (P<0.05). 【Conclusion】 TCM cardiac rehabilitation exercise combined with respiratory function training can effectively improve oxygenation function, cardiopulmonary function and exercise capacity, and enhance the quality of life of CHD patients after PCI, which plays a positive role in promoting postoperative rehabilitation.
