Purpose : Coronary artery bypass grafting (CABG) is an important viable option for patients with symptomatic or life-threatening ischemic heart disease. A few studies exist on CABG outcomes that indicate individual income status as a significantly important factor. This study was conducted to explore the impact of individual socioeconomic status (SES) on clinical outcomes after CABG.
Methods : A nationwide longitudinal population-based study was conducted in South Korea using the National Health Insurance Service database. A total of 29,810 adult patients who underwent first-time isolated CABG from 2005 to 2015 were included. SES was stratified into four categories (quartiles (Q) 1–4) according to the patient’s income level. The primary outcome was overall mortality.
Results : There was no significant difference in the in-hospital mortality rate between the lowest SES quartile (SES Q1 group) and the highest SES quartile (SES Q4 group). The risk for overall mortality increased significantly with reduction of SES, and SES Q1 was a significant predictor of worse long-term survival compared with SES Q4 (hazard ratio (HR), 1.23; 95% confidence interval (CI), 1.17–1.30). Moreover, the incidence of overall stroke was significantly higher in the SES Q1 group than in the SES Q4 group (HR, 1.13; 95% CI, 1.04–1.23). The median follow-up duration was 7.0 years (interquartile range, 4.1–10.2).
Conclusion : After adjusting for preoperative comorbidities, patients living in a lower individual SES were found to have an increased risk for poorer long-term outcomes of all-cause mortality and stroke after CABG.
