Abstract

Method:In this longitudinal population-based cohort study all patients aged 18-84 years with a first hospitalization for heart failure (HF) in Sweden 1992Sweden -2008 were identified using the National Inpatient Register (IPR). Longitudinal integration database for health insurance and labour market studies (LISA) is an integration database of several different national registers provided by the Statistics Sweden. Using the Swedish personal identity number (PIN) the IPR was linked to LISA and the Swedish National Register on Cause of Death to obtain information on marital status and education level, and mortality of all causes. Results: A total of 364,675 patients were included in the study. The relative risk of death among HF patients with the lowest educational level was 1.19 (95% CI 1.17-1.21) compared to those with the highest education level. Corresponding result for being unmarried versus married was 1.25 (95% CI 1.23-1.27). The 4-year cumulative survival for patients with low education and unmarried patients was 46.3% and 48.3% respectively.
