Key result
Cardiac rehab links to improved physical QoL across socioeconomic groups, while mental gains favor high education.
Why the study?
The study was conducted to analyze quality of life in cardiac rehabilitation participants according to monthly income and education levels in the early phase after PCI.

Does short-term cardiac rehabilitation improve quality of life according to socioeconomic status in patients after percutaneous coronary intervention?
Short-term cardiac rehabilitation after PCI improves physical quality of life across all socioeconomic strata, but mental quality of life improvements may be limited to those with higher education levels.
Short-term CR may improve physical QoL across SES but mental QoL only in higher education; leaves open targeted interventions for lower-SES patients.
Background Cardiac rehabilitation (CR) lowers the recurrence of cardiovascular disease and has strong and posi-tive physical and psychological effects. The purpose of this study was to analyze the quality of life (QoL) of CR participants according to their monthly income and education levels in the early phase after percutaneous coronary intervention (PCI). Material and methods There were 128 participants (98 men and 30 women). Their socioeconomic status (SES) was evaluated and QoL was assessed using the 36-item Short Form Health Survey. CR was initiated 3 weeks after treatment and remeasured after 3 months. The pre-post analysis was performed using the paired t-test. The participants’ education levels were defined in terms of a middle school group (low education [LE]), high school group (middle education [ME]), and above college group (high education [HE]). Monthly household income was divided into tertiles: up to US$2000 (low income [LI]), up to US$4000 (middle income [MI]), and more than US$4000 (high income [HI]). Results There was a significant increase in mental health status—from 54.9 to 63.3—in the HE group, but no significant changes were observed in the LE and ME groups. Physical changes were observed in all education-level groups. The physical changes in the group according to monthly income significantly increased by 9.1% (66.8– 73.5) in the LI group, 7.8% (65.9–71.5) in the MI group, and 12.1% (62.7–71.3) in the HI group. Physical changes were observed in all monthly income groups. Changes in occupational physical activity levels sig-nificantly improved physical and mental status in the middle and high activity groups, but not in the low activity group. Conclusion Changes in QoL as an effect of short-term CR were effective. Changes in mental QoL were significant in higher SES levels and physical QoL was effective in all groups.

Kim et al. (2019) conducted an observational in Early phase after percutaneous coronary intervention (PCI) (n=128). Short-term cardiac rehabilitation was evaluated on Quality of life (QoL) assessed using the 36-item Short Form Health Survey. Short-term cardiac rehabilitation significantly improved physical quality of life across all socioeconomic groups, while mental quality of life significantly improved only in the high education group.
