Income-Based Inequalities in Five-Year Survival after Coronary Artery Bypass Grafting and Percutaneous Coronary Intervention among Formally Employed Adults in Colombia: A Nationwide Cohort Study.

ABSTRACT:

Background

Myocardial revascularization by coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) lowers mortality, yet long-term outcomes may vary by socioeconomic status despite broadly similar access to care.

Objective

To examine the association between income-measured in legal monthly minimum wages (MMW)-and five-year survival after revascularization in formally employed Colombians (2012-2018).

Methods

This was a retrospective cohort study using linked national administrative datasets. Income was grouped into quartiles at cohort entry. The primary outcome was five-year mortality. Analyses were stratified by procedure (CABG, PCI). Multivariable Cox models were used to estimate adjusted hazard ratios (aHRs), controlling for age, sex, regi
