Abstract
AIMS Examine temporal changes in the risk of cardiovascular events in people with newly diagnosed type 2 diabetes with and without cardiovascular disease (CVD). METHODS 283,600 individuals with newly diagnosed type 2 diabetes and age-, sex-, and CVD-matched controls without diabetes were identified through Danish nationwide registries between 1997 and 2014. Using Cox regression models, we report the standardized absolute 5-year risk of cardiovascular death, myocardial infarction, stroke, and heart failure for people with diabetes and controls. RESULTS Individuals with newly diagnosed diabetes were at increased risk of cardiovascular events compared to controls. From 1997-2002 to 2009-2014 reductions in cardiovascular events for people with diabetes were: cardiovascular death; 26.5% to 13.8% in people with CVD and from 7.3% to 3.2% in people without CVD, myocardial infarction; 13.1% to 6.5% in people with CVD and from 4.1% to 1.9% in people without CVD, stroke; 14.2% to 8.8% in people with CVD and from 4.9% to 2.2% in people without CVD, and heart failure; 21.0% to 13.8% in people with CVD and from 5.0% to 2.6% in people without CVD. The risk of cardiovascular events declined more among people with diabetes than controls. CONCLUSIONS Newly diagnosed type 2 diabetes was associated with an increased risk of cardiovascular events, and the risk decreased significantly 1997-2014 in both people with and without CVD. Furthermore, the excess risk associated with type 2 diabetes decreased significantly during the study period.
