Higher education is associated with reduced risk of heart failure among patients with acute myocardial infarction: A nationwide analysis using data from the CVDNOR project
2016
AimsCoronary heart disease (CHD) outcomes are characterised by socioeconomic gradients. Although heart failure (HF) is a severe complication of CHD, sparse evidence exists on the association between socioeconomic status and HF among coronary patients. This study aimed to explore potential educational differences in the risk of HF among acute myocardial infarction (AMI) patients in Norway during 2001–2009.Methods and resultsA total of 70,506 patients hospitalised for an incident (first) AMI and without history of HF were included in the analyses. Information on education was obtained from the Norwegian Education Database and categorised into primary, secondary or tertiary. In 12,487 (17.7%) patients, HF was present at admission or developed during the AMI hospitalisation (early-onset HF). Compared to patients with primary education, patients with secondary or tertiary education had 9% [incidence rate ratio (IRR) = 0.91; 95% confidence interval (CI): 0.87–0.94] and 20% (IRR = 0.80; 95% CI: 0.75–0.86) lower ...
