Abstract

Objective In this study we aimed to estimate the effect of diabetes, educational level and income on the risk of mortality and cardiovascular events in primary care patients with hypertension. Methods We followed 62,557 individuals with hypertension diagnosed 2001-2008, in the Swedish Primary Care Cardiovascular Database. Study outcomes were death, myocardial infarction, and ischemic stroke, assessed using national registers until 2012. Cox regression models were used to estimate adjusted hazard ratios of outcomes according to diabetes status, educational level, and income. Results During follow-up, 13,231 individuals died, 9981 were diagnosed with diabetes, 4431 with myocardial infarction, and 4433 with ischemic stroke. Hazard ratios (95% confidence intervals) for diabetes versus no diabetes: mortality 1.57 (1.50-1.65), myocardial infarction 1.24 (1.14-1.34), and ischemic stroke 1.17 (1.07-1.27). Hazard ratios for diabetes and ≤9 years of school versus no diabetes and >12 years of school: mortality 1.56 (1.41-1.73), myocardial infarction 1.36 (1.17-1.59), and ischemic stroke 1.27 (1.08-1.50). Hazard ratios for diabetes and income in the lowest fifth group versus no diabetes and income in the highest fifth group: mortality 3.82 (3.36-4.34), myocardial infarction 2.00 (1.66-2.42), and ischemic stroke 1.91 (1.58-2.31). Conclusions Diabetes combined with low income was associated with substantial excess risk of mortality, myocardial infarction and ischemic stroke among primary care patients with hypertension.
