In DAPA-HF, the SGLT2 inhibitor (i) dapagliflozin (dapa) reduced worsening heart failure (HF) and cardiovascular death in 4744 patients (pts) with HF and reduced ejection fraction (HFrEF.) Only 45% had type 2 diabetes (T2D) at baseline. We evaluated whether dapa reduced the incidence of diabetes in the 55% of pts without T2D. Pts were randomized to dapa 10 mg or placebo and followed for a median of 18.2 months. New-onset T2D was defined as A1c ≥6.5% measured at 2 consecutive study visits post-randomization or investigator-reported new T2D (with the initiation of a glucose-lowering agent.) The effect of dapa on incident T2D was assessed using a Cox proportional hazards model and confirmed with a Fine and Gray competing risk model to account for mortality. Of the 2605 non-T2D pts at baseline, 157 developed T2D on trial, 150 (95.5%) of whom had prediabetes (A1c 5.7-6.4%) (136 [86.6%] using the more restrictive 6.0-6.4% criterion.) Those with incident T2D had a higher mean baseline A1c (6.2 ±0.3 vs. 5.7 ±0.4%; p<0.001), greater BMI (28.5 ±5.9 vs. 27.1 ±5.7 kg/m2; p=0.003), and lower eGFR (61.5 ±17.4 vs. 68.2 ±19.3 ml/min/1.73 m2; p<0.001) than those who remained nondiabetic. Dapa reduced new-onset diabetes by 32%: placebo 93/1307 (7.1%) vs. dapa 64/1298 (4.9%); HR 0.68 (95% CI, 0.50-0.94; p=0.019) (Cox.) Results were virtually identical using the Fine and Gray model. Diabetes prevention may be another benefit of dapagliflozin.
