Abstract

Objective: Heart failure (HF) often develops in patients with diabetes and is recognized for its role in increased cardiovascular morbidity and mortality in this population. Most existing models predict risk in patients with prevalent rather than incident diabetes and fail to account for sex differences in HF risk factors. We derived sex-specific models in Ontario, Canada to predict HF at diabetes onset and externally validated these models in the UK. Research Design and Methods: Retrospective cohort study using international population-based data. Our derivation cohort comprised all Ontario residents aged ≥18 years, who were diagnosed with diabetes between 2009-2018. Our validation cohort comprised UK patients aged ≥35 years, who were diagnosed with diabetes between 2007-2017. Primary outcome was incident HF. Sex-stratified multivariable Fine and Gray subdistribution hazard models were constructed, with death as a competing event. Results: A total of 348,027 Ontarians (45% women) and 54,483 UK residents (45% women) were included. At 1, 5, and 9 years, respectively in the external validation cohort, the C-statistics were 0.81 (95%CI: 0.79-0.84), 0.79 (0.77-0.80), and 0.78 (0.76-0.79) for the female-specific model; 0.78 (0.75-0.80), 0.77 (0.76-0.79), and 0.77 (0.75-0.79) for the male-specific model. The models were well-calibrated. Age, rurality, hypertension duration, hemoglobin, HbA1C, and cardiovascular diseases were common predictors in both sexes. Additionally, mood disorder and alcoholism were female-specific predictors, while income and liver disease were male-specific predictors. Conclusions: Our findings highlight the importance of developing sex-specific models and represent an important step towards personalized lifestyle and pharmacologic prevention of future HF development.
