ABSTRACT
The DAPA-HF trial demonstrated that sodium-glucose cotransporter 2 inhibitors (SGLT2i) reduced worsening heart failure (HF) events in chronic HF patients with or without type 2 diabetic mellitus (T2DM). However, it remains unclear whether the effectiveness of SGLT2i is also observed in patients with decompensated HF irrespective of HbA1c level. Eighty-one T2DM patients hospitalized due to decompensated HF were enrolled and divided into 2 groups according to their HbA1c levels (group H, HbA1c 6.9-13.0%, n = 41; group L, HbA1c < 6.9%, n = 40). After the initial management of HF, one of the SGLT2i (canagliflozin 100 mg/day or dapagliflozin 5 mg/day or empagliflozin 10 mg/day) was non-randomly administered, and clinical parameters associating with HF and T2DM were followed for 7 days. No symptomatic hypoglycemia was observed in any patient. In both groups, urine glucose excretion was increased significantly after the administration of SGLT2i. However, its amount was greater in group H than group L. Urine volume was increased significantly at day 1 in both groups. Urine volume returned to the baseline after one week in group L. In contrast, the increase in urine volume persisted at least for one week in group H. Of note, a decrease in B-type natriuretic peptide levels after the initiation of SGLT2i was observed in both groups similarly despite differences in urine output and excretion of urine glucose. In conclusion, SGLT2i can improve decompensated HF in patients with T2DM irrespective of the HbA1c level.
