BackgroundScientific knowledge on disability pension (DP) after revascularization by coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) is scarce. The aim was to study the incidence of and risk factors for being granted DP in the 5 years following a first CABG or PCI, accounting for socio-demographic and medical factors.MethodsThis is a nationwide population-based study using Swedish registers including all patients 30-63 years of age (n = 34,643, 16.4% women) who had a first CABG (n = 14,107) or PCI (n = 20,536) during 1994-2003. All were alive and without reintervention 30 days after the procedure and were not on DP or old-age pension. Multivariable adjusted Cox proportional hazard ratios (HR) for DP were estimated with 95% confidence intervals (CI).ResultsIn 5 years following revascularization, 32.4% had been granted DP and the hazard ratio (HR) was higher in women (HR 1.55, 95% CI 1.48-1.62), and in CABG patients compared with PCI patients (HR 1.35, 95% CI 1.30-1.40). Long-term sick leave in the year before intervention was the strongest predictor for DP following revascularization. After adjustments for socio-demographic factors and sick-leave days in the 12 months before revascularization, HR remained high in all patients with diabetes mellitus regardless of type of revascularization.ConclusionsDP after coronary revascularization was common, especially among women and CABG patients. Most studied medical covariates, including mental and musculoskeletal disorders, were risk factors for future DP, especially long-term sickness absence.© The European Society of Cardiology 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.
