Objective: To systematically evaluate the effects of different exercise on cardiopulmonary reserve function and exercise endurance in patients with coronary heart disease. Methods: A randomized controlled study was searched from the databases of China National Knowledge Infrastructure(CNKI), Wanfang Data Knowledge Service Platform(Wanfang Data), VIP, SinoMed, PubMed, Web of Science, The Cochrane Library, and Embase on improving cardiovascular reserve function and exercise endurance in patients with coronary heart disease through exercise methods. The search was conducted from inception through April 2023. After two researchers independently screened the literature, extracted data, and evaluated the risk of bias in the included literature, RevMan 5.3, Stata16.0, and R4.2.2 were selected for statistical analysis. Results: A total of 30 studies were included, with 2 433 patients with coronary heart disease. The results of a network Meta-analysis showed that in terms of improving LVEF, the best 2 exercise modes were aerobic combined with resistance exercise and aerobic exercise; the two best exercise methods for increasing 6MWT were resistance exercise and aerobic combined resistance exercise; in terms of improving lung function, the two best exercise methods were resistance exercise and yoga. However, due to limitations in the quality and quantity of studies included, high-quality research is still needed for further validation. Conclusion: Exercise can improve cardiovascular reserve function and exercise endurance in patients with coronary heart disease, but the focus of different exercises on improving heart function varies, among which, aerobic combined with resistance exercise has the most significant effect on improving LVEF and 6MWT, while resistance exercise has a better effect on improving 6MWT and FEV1/FVC%. |
