Impact of Inpatient Initiation of SGLT2 Inhibitors on Diuretic Requirements in Patients With Heart Failure
Abstract
Background: Sodium-glucose cotransporter 2 inhibitors (SGLT2i) have been shown to improve outcomes in patients with heart failure (HF) and are now included in guideline-directed medical therapy. Trials reporting the change in loop diuretic dose following SGLT2i initiation have indicated conflicting results. There is no clear guidance on whether reducing loop diuretic doses following SGLT2i initiation is appropriate. Objective: The purpose of this study is to assess the impact of SGLT2i initiation on diuretic adjustment in hospitalized patients with known or new HF. Methods: This was a retrospective, single health-system study assessing the change in loop diuretic dose in the 60 days following discharge for patients with HF initiated on SGLT2i therapy during a hospital admission or upon discharge. Secondary outcomes assessed effect on renal function and discontinuation of SGLT2i within the 60 day follow up period. Results: Forty percent of patients required loop diuretic dose adjustment, with 29% requiring a dose reduction within the 60 days following discharge. There was minimal change in serum creatinine or blood urea nitrogen. The SGLT2i was discontinued in 6 patients. Conclusions: After inpatient initiation of SGLT2is, approximately one-third of patients required a reduction in loop diuretic dose within 60 days following hospital discharge. Further study is recommended to confirm if empiric diuretic dose adjustments are appropriate in this HF population.
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 6 participants or records.
