Objectives: To investigate social and gender equality in access to coronary revascularization for those treated for coronary heart disease in Sweden between 1991 and 2000.
Design: All Swedish residents between 25 and 74 years old with a hospital stay for coronary heart disease were eligible for the study, in total about 153,000 persons. The Swedish Hospital Discharge Register from 1988 through 2000 was used to define the study population. Poisson regression analyses were used to estimate the effect of socio-economic status on the likelihood for coronary artery bypass grafting (CABG) within 2 years. In the analysis of gender differences, the likelihood for percutaneous coronary intervention (PCI) was also included.
Results: Males were 1.5 times more likely to undergo revascularization procedures than females even after adjusting for confounding factors and the fact that women are less eligible for interventions. The analyses also showed significant socio-economic inequalities in access to CABG among men, but not among women.
Conclusions: There are gender and socio-economic inequalities in access to cardiac procedures in Sweden.
