Early initiation of SGLT2 inhibitors is important, irrespective of ejection fraction: SOLOIST‐WHF in perspective

ABSTRACT

The ultimate primary endpoint of SOLOST‐WHF—which in order to preserve statistical power was changed because of the premature closure of the study due to loss of funding from the sponsor during the onset of the COVID‐19 pandemic—was the composite of total HHF, urgent heart failure visits, or cardiovascular deaths. The HR for the primary outcome was apparently similarly reduced in all groups (0.69, 0.74, and 0.66, respectively). Because the subgroup of patients with ejection fraction above 50% was modest in size, further data of SGLT2 inhibitors in heart failure with preserved ejection fraction (HFpEF) are eagerly anticipated. 2 Figure.
