Authors' conclusion

Use of SGLT2i increased three-fold over 2 years.

Study context

Population
Patients with HF with reduced ejection fraction (HFrEF) (EF <40%), no type 1 diabetes, estimated glomerular filtration rate (eGFR) <20 ml/min/1.73 m² and/or on dialysis, Swedish HF Registry, 1 November 2020 to 5 August 2022
Participants
8,192 patients
Outcome
Implementation of SGLT2i over time and patient characteristics associated with their use

Main finding

As reported in the abstract

SGLT2i use

Received SGLT2i

37%

Use over time, overall

from 20.5% to 59.0%

Observational data: associations, not effects.

Further findings

SGLT2i use over time, by subgroup

With vs without T2DM
from 46.2% and 12.5% to 69.8% and 55.4%
eGFR <60 vs ≥60 ml/min/1.73 m²
from 14.7% and 22.3% to 58.0% and 59.8%
Males vs females
from 21.0% and 18.9% to 61.6% and 52.0%
With vs without recent HF hospitalization
from 24.2% and 18.0% to 60.8% and 57.7%
Inpatients vs outpatients
from 26.1% and 19.8% to 54.7% and 59.6%
HF duration <6 vs ≥6 months
from 20.2% and 21.2% to 59.2% and 58.7%

Characteristics associated with SGLT2i use (multivariable logistic regression)

More use: male sex, recent HF hospitalization, specialized HF follow-up, lower EF, T2DM, higher education level, use of other HF/CV interventions
Less use: older age, higher BP, AF, anaemia

Discontinuation of SGLT2i · 6 and 12 months

Discontinuation at 6 months
13.1%
Discontinuation at 12 months
20.0%
