Objective Diuretics reduce congestion in patients with heart failure with preserved ejection fraction (HFpEF). However, comparison of clinical effects across diuretic classes or combinations of diuretics in patients with HFpEF are not well described. Therefore, we sought to conduct a scoping review to map trial data of diuretic efficacy and safety in patients with HFpEF. Review methods and results We searched multiple bibliometric databases for published literature and ClinicalTrials.gov, and hand searched unpublished studies comparing different classes of diuretics to usual care or placebo in patients with HFpEF. We included randomised controlled trials or quasi-experimental studies. Two authors independently screened and extracted key data using a structured form. We identified 13 published studies on diuretics in HFpEF, with 1 evaluating thiazide use, 7 on mineralocorticoid receptor antagonists (MRAs) and 5 on sodium-glucose co-transporter 2 inhibitors (SGLT2i). There remain 17 ongoing trials evaluating loop diuretics (n=1), MRAs (n=5), SGLT2i (n=10) and a polydiuretic (n=1), including 2 well-powered trials of SGLT2i that will be completed in 2021. Conclusions The limited number of published trials evaluating different classes of diuretics in patients with HFpEF have been generally small and short term. Ongoing and emerging trials of single or combination diuretics with greater power will be useful to better define their safety and efficacy. Scoping review registration doi:10.18131/g3-dejv-tm77.
