Background
The prognostic importance of new-onset type 2 diabetes (T2D) in heart failure (HF) remains unknown. We aimed to describe the cardiovascular outcome profile in HF patients with new-onset, no and prevalent T2D.
Methods
We constructed a cohort of patients with first HF admission between 1998 and 2016 from nationwide Danish registers. Outcomes were ischemic event, HF event, and death from other causes. The landmarking approach and the Aalen Johansen estimator were used together to estimate 5-year absolute and 5-year relative risk of the outcomes in HF patients with new-onset, no and prevalent T2D. Risk among subgroups were investigated by stratification.
Results
A total of 139 264 HF patients were included between 1998 and 2016, of which 29 078 patients had prevalent T2D. A total of 11 819 developed new-onset T2D. The 5-year risks of ischemic event in new-onset, no, and prevalent T2D were: 17.9% [17.2; 18.6], 18.8% [18.6; 19.0], and 26.1% [25.6; 26.7]. The 5-year risks of HF event were: 31.5% [30.6; 32.3], 30.7% [30.5; 31.0], and 33.6% [33.0; 34.2]. For other causes of death, the 5-year risks were: 20.9% [20.2; 21.7], 18.6% [18.4; 18.8], and 18.9% [18.4; 19.3]. The 5-year risk ratios of HF event or death from other causes versus ischemic event were: 2.9 [2.8; 3.1], 2.6 [2.6; 2.7], and 2.0 [2.0; 2.1] in patients with new-onset, no, and prevalent T2D.
Conclusions
In patients with new-onset T2D, death from other causes were more likely to occur than an ischemic event, whereas in patients with prevalent T2D and no T2D, ischemic events were more common.
