Patients with HFpEF and diabetes mellitus will receive polydiuretic therapy consisting of bumetanide 0.5 mg + eplerenone 25 mg + dapaglifozin 5 mg on top of background therapy. These medicines are currently FDA approved and recommended by clinical practice guidelines for the treatment of HFpEF (bumetanide, eplerenone) and diabetes mellitus (dapaglifozin).~This study is designed to evaluate if combination pharmacotherapies with synergistic or additive diuretic properties can improve adherence, treatment efficacy, and effectiveness with fewer side effects
This is a single-center, non-randomzied pilot study investigating a combination of targeted therapies as possible treatment for heart failure with preserved ejection fraction (HFpEF).~The study interviention is a Low-Dose, Triple Polydiuretic Therapy (LDTPT, or polydiuretic) including loop diuretic (bumetanide), mineralocorticoid receptor antagonist (eplerenone), and Sodium-glucose co-transporter 2 inhibitors (SGLT2i) therapy (dapaglifozin).
