3. Current symptoms of Heart Failure (NYHA ≥ II) during VR
4. Symptom(s) of HF ≥ 30 days prior to VR
5. HF Hospitalization or treatment with intravenous (IV) diuretics for worsening HF within 12 months prior to VR
6. Left ventricular ejection fraction ≥ 40 % at screening measured by echocardiography and evidence of structural/ functional abnormalities (at least one of the following criteria): LAVI > 34 ml/m2// E/émean ≥ 13// Mean e' (septal and lateral) < 9 cm/s
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.

1. Hyperkalemia (potassium level ≥ 5.5 mmol/L) within the past two weeks before VR
2. Hyponatraemia (sodium level < 135 mmol/L) prior to randomization
3. Severe renal dysfunction, defined as an estimated glomerular filtration rate of less than 30 mL/min/1.73m2) as calculated by the Modification in Diet in Renal Disease (MDRD) formula at Visit 1 or serum creatinine level ≥ 1,8 mg/dl (> 160 μmol/ml)
4. History of anuria or acute renal failure (as defined by the RIFLE criteria for AKI; see Appendix XVIII.3) within the past two weeks before VRenal dysfunction, defined as an estimated glomerular filtration rate of less than 30 mL/min/1.73m2) as calculated by the Modification in Diet in Renal Disease (MDRD) formula at VScr/VR or serum creatinine level ≥ 1,8 mg/dl (> 160 μmol/ml)History of anuria or acute renal failure (as defined by the RIFLE criteria for AKI; see Appendix XVIII.3) within the past two weeks prior to randomization
5. Acute coronary syndrome (including MI) and elective PCI within 30 days prior to VR.
6. Cardiac surgery, other major CV surgery, or urgent percutaneous coronary intervention (PCI) within the 3 months prior to VR
7. Current acute decompensated HF requiring augmented therapy with i.v. diuretics, i.v. vasodilators and/or i.v. inotropic drugs. Patients are eligible after initial stabilization.

8. Probable alternative diagnoses that in the opinion of the investigator could account for the patient's HF symptoms (i.e., dyspnea, fatigue) such as significant pulmonary disease (including primary pulmonary HTN), anemia or obesity. Specifically, patients with the following are not eligible for randomization:

   • Severe pulmonary disease including chronic obstructive pulmonary disease (COPD) or severe asthma bronchiale ( (ie requiring home oxygen, chronic nebulizer therapy, chronic oral steroid therapy) or
   • anemia (hemoglobin < 10 g/dL males and < 9.5 g/dL females), or
   • body mass index (BMI) > 40 kg/m2
9. Evidence of right sided HF in the absence of left-sided structural heart disease.
10. Specific etiologies such as infiltrative, genetic hypertrophic cardiomyopathy, pericardial constriction, sarcoidosis, amyloidosis and any other storage diseases.
11. Clinically significant congenital heart disease underlying heart failure.
12. Life-threatening or uncontrolled dysrhythmia, including symptomatic or sustained ventricular tachycardia and uncontrolled persistent or permanent atrial fibrillation (AF) or flutter (with a heart rate > 100 beats per minute (bpm), RACE II) during VR. If AF with HR > 100/min, the patient may be rescreened after treatment for rate control.
13. Presence of significant (i.e., more than moderate) valvular heart disease expected to lead to surgery during the trial in the investigators opinion.
14. Stroke, transient ischemic attack, carotid surgery or carotid angioplasty within the 3 months prior to VR.
15. Coronary or carotid artery disease or valvular heart disease likely to require surgical or percutaneous intervention within the 6 months after VR in the investigators opinion.
16. Patients with prior major organ transplant or intent to transplant (on transplant list) or with current ventricular assist device (VAD) therapy.
17. Evidence of hepatic disease as determined by any one of the following: SGOT (AST) or SGPT (ALT) values exceeding 3x the upper limit of normal (ULN), bilirubin >1.5 mg/dl at VR.
18. Evidence of present bilateral renal artery stenosis
19. Known intolerance or history of hypersensitivity to the active substance (Spironolactone) or to any of the excipients of the Investigational Medicinal Product (IMP) or placebo.
20. Present use of any aldosterone antagonist, potassium supplements or potassium sparing diuretics at the time of enrollment. (Consider stopping these potassium sparing drugs if clinically possible and upon discussion with the patient)

21. Required treatment with prohibited Co-medications according to the summary of product characteristics with the exception of ACE inhibitors or angiotensin receptor blockers (as described in the protocol in IV.2).

    , careful monitoring of plasma lithium and dose adjustment are required.

22. Use of other investigational drugs at the time of enrollment, or within 30 days or 5 half-lives before enrollment, whichever is longer.
23. Any condition that, in the opinion of the investigator may prevent the subject from adhering to the study protocol (e.g. history of non-compliance to medical regimens, patients who are considered potentially unreliable, patients with a history of addiction).
24. History or presence of any other disease (i.e. including malignancies) with a life expectancy of < 1 years.
25. History of non-compliance to medical regimens and patients who are considered potentially unreliable.
26. Subjects who are legally detained in an official institution.
27. Subjects who may be dependent on the sponsor, the investigator or the trial sites, have to be excluded from the trial.
28. Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive human chorionic gonadotropin (hCG) laboratory test.
29. Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception during study participation and until 2 months after the last dose off study drug.
