Brief summary: The purpose of this study is to determine whether the treatment of patients with HFmrEF and HFpEF at high risk of cardiovascular events with the mineralocorticoid receptor antagonist (MRA) spironolactone reduces a composite of recurrent heart failure hospitalizations and cardiovascular mortality.

Detailed description: The primary objective of the SPIRIT-HF study is to compare Spironolactone to Placebo in reducing the rate of the composite endpoint of recurrent heart failure hospitalizations and cardiovascular (CV) death in symptomatic HF patients (NYHA II-IV) with mid-range (LVEF 40- 49 %) or preserved (LVEF ≥ 50 %) ejection fraction.

The efficacy and safety of mineralocorticoid receptor antagonist (MRA) in reducing the risk of death and hospitalizations has been proven with two separate substances (Spironolactone; RALES 1999 and Eplerenone; EMPHASIS 2011) in symptomatic heart failure patients with reduced left- ventricular ejection fraction (HFrEF). In 2013 the TOPCAT investigators tried to proof similar efficacy in patients with heart failure and preserved ejection fraction (≥ 45%). Because of regional variations in the enrollment process and difficulties regarding drug adherence the trial revealed neutral findings but the substance spironolactone was still able to show its potential benefit in the American cohort. Hence, the investigators see a strong rationale for testing a mineralocorticoid receptor blocker in patients suffering from heart failure with mid-range or preserved left ventricular ejection fraction.

Intervention:

Mineralocorticoid receptor blocker Spironolactone in tablet form taken daily. Starting dosage will be 25 mg OD with dosage escalation to 50 mg OD within 4 weeks if kidney function at VR was \> 30 mL/min/m2 and potassium \< 4.5 mmol/L. Spironolactone is not approved for the treatment of HFmrEF and HFpEF.

Matching placebo in tablet form taken daily with dosage escalation rules in accordance with dosage of the study drug Spironolactone.

Visits:

Screening (VScr), Visit of Randomization (VR), V1 Safety Visit (1 week), V2 (4 weeks), V2S Safety Visit (5 week), V3 (4 months), V4 (8 months), V5 (12 months), V6 (18 months), V7 (24 months), V8 (30 months), V9 (36 months), V10 (42 months), V11/EOT (48 months); VXS (1 week after Visit X).

Individual intervention duration with spironolactone or placebo will be continued until the overall expected event rate is reached or until withdrawal of informed consent. Based on previous HF trials the investigators calculate a mean follow-up duration of 3 years (range 2-4 years) depending on the individual inclusion date.

Duration of follow-up will be event-rate based, with an expected overall study duration of 60 months. With an anticipated recruitment phase of 24 months; this will result in a maximum follow-up of 48 months and an average follow-up per patient of 36 months assuming a constant recruitment rate.

Eligibility criteria: Inclusion Criteria:

Patients eligible for inclusion in this study have to fulfill all of the following criteria:

1. Written informed consent.
2. Male or female, age ≥ 50 years
3. Current symptoms of Heart Failure (NYHA ≥ II) during VR

7. NT-proBNP \> 300 pg/ml (SR) or \> 900 pg/ml (AF) on the Visit 1 ECG; only if NT-proBNP is NOT available: BNP \> 80/ 250 pg/ml (SR/AF)
8. Controlled systolic BP: defined as a target systolic BP \< 140 mm Hg. Subjects with BP up to and including 160 mm Hg are eligible for enrollment if on 3 or more medications to control BP (Patients with uncontrolled BP should be considered for Re-Screening after optimization of antihypertensive therapy has been established)
9. Serum potassium \< 5.0 mmol/L prior to randomization

Exclusion Criteria:

Patients fulfilling any of the following criteria are not eligible for inclusion in this study. The investigator may apply no additional exclusion criteria, in order to ensure that the study population will be representative of all eligible patients.
