Some types of exercise interventions are more effective than others in people with coronary heart disease: systematic review and network meta-analysis

Question: What are the effects of different types of exercise treatments on oxygen consumption, quality of life and mortality in people with coronary heart disease? Design: Systematic review with network metaanalysis of randomised controlled trials. Participants: Adults with coronary heart disease. Intervention: Exercise interventions including aerobic (continuous or high -intensity interval) training, resistance training, respiratory muscle exercises, water -based exercises, yoga, Tai chi, Qigong exercises and a combination of different types of exercise. Outcome measures: Oxygen consumption, quality of life and mortality. Results: This review included 178 randomised controlled trials with 19,143 participants. Several exercise interventions improved peak oxygen consumption (mL/kg/min): high -intensity interval training (MD 4.5, 95% CI 3.7 to 5.4); combined water -based exercises and moderate -intensity continuous training (MD 3.7, 95% CI 1.3 to 6.0); combined aerobic and resistance exercise (MD 3.4, 95% CI 2.5 to 4.3); water -based exercises (MD 3.4, 95% CI 0.6 to 6.2); combined respiratory muscle training and aerobic exercise (MD 3.2, 95% CI 0.6 to 5.8); Tai chi (MD 3.0, 95% CI 1.0 to 5.0); moderate -intensity continuous training (MD 3.0, 95% CI 2.3 to 3.6); high -intensity continuous training (MD 2.7, 95% CI 1.6 to 3.8); and resistance training (MD 2.2, 95% CI 0.6 to 3.7). Quality of life was improved by yoga (SMD 1.5, 95% CI 0.5 to 2.4), combined aerobic and resistance exercise (SMD 1.2, 95% CI 0.6 to 1.7), moderate -intensity continuous training (SMD 1.1, 95% CI 0.6 to 1.6) and high -intensity interval training (SMD 0.9, 95% CI 0.1 to 1.6). All -cause mortality was reduced by continuous aerobic exercise (RR 0.67, 95% CI 0.53 to 0.86) and combined aerobic and resistance exercise (RR 0.58, 95% CI 0.36 to 0.94). Continuous aerobic exercise also reduced cardiovascular mortality (RR 0.56, 95% CI 0.42 to 0.74). Conclusion: People with coronary heart disease may use a range of exercise modalities to improve oxygen consumption, quality of life and mortality. Registration: PROSPERO CRD42022344545.
