Description of intervention(s) / exposure
Treatment: Drugs - Low dose combination polydiuretic therapy
Treatment: Drugs - Comparator monotherapy empagliflozin

Experimental: Patients receiving low dose combination polydiuretic therapy - This patient group will receive a low dose combination polydiuretic therapy treatment consisting of: bumetanide 0.5 mg (loop diuretic), eplerenone 25 mg (mineralocorticoid receptor antagonist) and empagliflozin 10mg (sodium-glucose co-transporter 2 inhibitor) daily on top of their background therapy.

Active comparator: Comparator group receiving monotherapy empagliflozin - This comparator patient group will receive empagliflozin 10mg (sodium-glucose co-transporter 2 inhibitor) daily on top of their background therapy.

Eligibility
Key inclusion criteria
1. Have provided written informed consent
2. Adults = 18 years old
3. Established diagnosis of NYHA Class II - IV heart failure with preserved ejection fraction, which has been present for at least 2 months
4. Left ventricular ejection fraction =50% on echocardiography within the last 12 months prior to study enrolment, and no previous echocardiogram with EF < 40% NB: Patients in which additional pharmacological or device therapy is contemplated, or should be considered, must not be enrolled until therapy has been optimised and is stable for = 1 month.
5. NT-proBNP >300 pg/ml (or if hospitalised for heart failure within the previous 12 months, NT-proBNP =400 pg/ml) at enrolment. If concomitant atrial fibrillation at Visit 1, NT-proBNP must be =900 pg/ml (irrespective of history of heart failure hospitalisation)
Minimum age

Key exclusion criteria
1. Known contraindication to bumetanide, eplerenone, or empagliflozin.
2. Concurrently prescribed prohibited medications which are mineralocorticoid receptor antagonists (Spironolactone and Eplerenone) and SGLT2i agents.
3. Symptomatic hypotension or systolic BP <95 mmHg at 2 out of 3 measurements at Visit 0
4. Current acute decompensated HF or hospitalisation due to decompensated HF <4 weeks prior to enrolment.
5. Myocardial infarction, unstable angina, stroke, or transient ischaemic attack (TIA) within 12 weeks prior to enrolment.
6. HF due to restrictive cardiomyopathy, active myocarditis, constrictive pericarditis, hypertrophic (obstructive) cardiomyopathy or uncorrected primary valvular disease or reduced EF < 50%
7. Symptomatic bradycardia or second or third-degree heart block without a pacemaker.
