Abstract Background Cardiac rehabilitation (CR) is a secondary prevention intervention for coronary heart disease that has well-established efficacy in reducing mortality, morbidity, and cardiovascular risk factors. However, outcomes from CR are known to differ between population groups, with ethnic minorities reported to have health outcome disparities. However, there is no synthesis of these CR outcomes for ethnic minority populations. Purpose The main purpose of this study was to evaluate the impact of CR on rates of mortality, morbidity, and important cardiovascular risk factor outcomes including exercise performance, exercise capacity, low-density lipoproteins, cholesterol levels, body mass index, weight, waist circumference and systolic blood pressure, within ethnic minority groups. Methods Four electronic databases (Medline, EMBASE, CINAHL, Scopus) were searched from February to September 2021, for studies that reported CR outcomes of ethnic minorities. Potential papers were independently screened by two reviewers, and discrepancies were resolved by a third reviewer. Data was extracted from the studies using an electronic data extraction form. Meta-analyses for eligible studies were performed using Revman 5.4. Risk of bias were assessed using the Cochrane Tool. Results Across 13 studies (n = 132,109 participants), the 10,494 participants of ethnic minority groups achieved significant improvements in mortality, morbidity, and most cardiovascular risk factor outcomes including exercise performance, exercise capacity, body mass index, waist circumference, and systolic blood pressure. However, while ethnic minority groups achieved equivalent outcomes from CR for exercise performance and low-density lipoproteins, some outcomes were worse (exercise capacity, body mass index, waist circumference, systolic blood pressure). In addition, minority participants had greater reductions in cholesterol levels. Conclusion Ethnic minority groups achieve important improvements in mortality, morbidity, and cardiovascular risk factor outcomes from CR, although to a lesser extent than majority groups. Therefore, this information can be used to support efforts to improve participation in CR and prompt changes to the delivery of CR services for ethnic minority participants.
