MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Management of diabetes has improved in the past decades, studies have shown that mortality and cardiovascular disease among patients with diabetes has decreased, but these studies have not compared the trends among persons with type 1 diabetes and type 2 diabetes to those of the general population, where there have also been reductions in cardiovascular morbidity and mortality.
We observed marked reductions in incidence for cardiovascular disease and mortality among individuals with diabetes, however, similar trends were observed for the general population. We observed a 43% (HR 1.43, 95% CI 1.25–1.62) greater event rate reduction for cardiovascular disease among individuals with type 1 diabetes compared to matched controls. The reduction in the rate of fatal outcomes did not differ significantly between patients with type 1 diabetes and controls, whereas patients with type 2 diabetes had a 13% (HR 0.87, 95% CI 0.85–0.89) lesser event rate reduction compared with matched controls.
There was a 27% (HR 1.27, 95% CI 1.22–1.32) greater event rate reduction for cardiovascular disease among individuals with type 2 diabetes, compared with matched controls. Nevertheless, there remains a substantial excess overall rate of all outcomes analysed among persons with type 1 diabetes and type 2 diabetes, as compared with the general population.
