Authors' conclusion

In this real-world population with HFrEF, SGLT2i initiation was associated with a decrease in loop diuretic need at 1-year follow-up.

Study context

Population
Patients with HF with reduced ejection fraction (HFrEF) enrolled in the SwedeHF between January 2020 and October 20215,623 (81.6%) controls and 1265 (18.4%) cases were analysed · controls 5,623 · cases 1,265
