Study information

Scientific title



Study hypothesis

The primary objective of this study is to determine in subjects with diastolic heart failure whether spironolactone is superior to placebo in improving maximal exercise capacity and diastolic heart function. Secondary objectives of this study are to determine in subjects with diastolic heart failure whether spironolactone is superior to placebo in improving several other measures of exercise capacity and diastolic function, as well as quality of life, neuroendocrine activation, morbidity and mortality. The study will also investigate clinical safety aspects.

Ethics approval

Local ethics committee in Göttingen and the BfAM.

Patient information sheet


Diastolic heart failure


Once randomised, all patients will take study medication (25 mg spironolactone or placebo) once daily in the morning for 12 months. Patients recruited in the first six months will be followed up to 18 months. Spironolactone will be applied in one fixed dose, i.e., 25 mg, but may be down titrated if indicated.

Intervention type



Phase II

Drug names


Primary outcome measure

1. Change in maximum exercise capacity (peak VO2 on spiroergometry) at 12 months compared to baseline
2. Change in E/E´ (relation peak early transmitral ventricular filling velocity/early diastolic tissue Doppler velocity) as indicator of Left Ventricular End Diastolic Pressure (LVEDP) at 12 months

Secondary outcome measures

1. Change in primary endpoints at 18 months
2. Change in the echocardiographic Grade of diastolic dysfunction
3. Change in neuroendocrine activation (natriuretic peptides)
4. Change in six minutes walking distance
5. Change in quality of life (Minnesota living with heart failure questionnaire; Short Form Health Survey [SF-36])
6. Combined and separately morbidity and mortality (all-cause; cardiovascular)
