Despite progress in prevention and treatment, coronary artery disease (CAD) remains the leading cause of health loss globally  and the most common cause of death related to cardiovascular disease (CVD) . For a long time, underrepresentation of migrants, women, and older adults in CVD trials has likely contributed to disparate care and survival. Not only does prevention and on-time diagnosis impact patients’ outcomes, but so does management including rehabilitation. Missing any of these points can be crucial.
N. Gonzalez-Jaramillo et al. suggested that among underrepresented groups undergoing percutaneous coronary intervention (PCI), age, but not migration status nor sex, contributed to disparities in mortality. Migrant status did not result in lower attendance of cardiac rehabilitation (CR). Considering the protective associations of CR on CVD mortality independent of age, sex and migration status, the lower uptake in women and older adults is noteworthy . Despite the specificity of their clinical setting, their results indicate the need to evaluate if inclusive policies at the country and health-system levels may help overcome health disadvantages and exclusions in migrants. By comparing how rates of CR uptake among migrants and nationals change over time, future studies should evaluate the impact of health policies addressing health inequities in the migrant population . However, in most centres, the same as in the analysed cohort of PCI patients by N. Gonzalez-Jaramillo, ambulatory CR is the intervention of choice, whereas stationary CR is preferred after coronary artery by-pass grafting, valve surgery, and percutaneous aortic valve replacement .
According to N. Gonzalez-Jaramillo et al., after the first major adverse cardiovascular events (MACE), 11% of patients had a second MACE, 5% died from cardiovascular causes, and 2% died from other causes. Age was associated with a significant risk for non-CVD mortality as a first transition, and CVD mortality in all the transitions, but not with MACE. For each year of increase in age, participants had an 8% increased risk of non-CVD and CVD mortality after PCI in the first transition. 
There are different causes of missing cardiac rehabilitation in the underrepresented population. Awareness of ethnicity, the language spoken and the need for an interpreter would then allow providers such as the cardiac rehabilitation team to address issues related to health literacy as evidence suggests that those with greater cardiac knowledge are more likely to attend CR . While the recently published study highlighted the importance and positive outcomes of cardiac rehabilitation in underrepresented groups, it also promotes that every CVD patient should be included in CR programmes. I suggest authors extend their study by comparing described patients with those who underwent open-heart surgery. And the future perspectives are to organize both inpatient and outpatient CR programmes, as well as onsite and virtual.
