Background: The influence of diabetes on progression from preclinical heart failure (HF) stages to overt HF is poorly understood.
Objectives: The purpose of this study was to characterize the influence of diabetes on the progression from preclinical HF stages (A or B based on the 2021 Universal Definition) to overt HF.
Methods: We included 4,774 adults with preclinical HF (stage A [n = 1,551] or B [n = 3,223]) who attended the ARIC (Atherosclerosis Risk In Communities) study Visit 5 (2011-2013). Within each stage (A or B), we assessed the associations of diabetes and glycemic control (hemoglobin A1C [HbA1C] <7% vs ≥7%) with progression to HF, and of cross-categories of HF stages (A vs B), diabetes, and glycemic control with incident HF.
Results: Among the participants (mean age 75.4 years, 58% women, 20% Black), there were 470 HF events during 8.6 years of follow-up. Stage B participants with HbA1C ≥7% experienced clinical HF at a younger age than those with controlled diabetes or without diabetes (mean age 80 years vs 83 years vs 82 years; P < 0.001). HbA1C ≥7% was more strongly associated with HF in stage B (HR: 1.83; 95% CI: 1.33-2.51) compared with stage A (HR: 1.52; 95% CI: 0.53-4.38). In cross-categories of preclinical HF stage and HbA1C, participants with stage B and HbA1C ≥7% had increased risk of HF progression compared with stage A without diabetes (HR: 7.56; 95% CI: 4.68-12.20).
Conclusions: Among older adults with preclinical HF stages, uncontrolled diabetes was associated with substantial risk of HF progression. Our results suggest that targeting diabetes early in the HF process is critical.
