Conditions

Heart Failure With Preserved Ejection Fraction

Brief summary

The goal of this double-blind randomized, placebo-controlled cross-over trial is to evaluate the effectiveness of GerenylGeranylAcetone (GGA) in patients with Heart Failure with a preserved ejection fraction. The main questions it aims to answer are: * What is the effect of GGA on diastolic function? * What is the effect of GGA on endothelial function? Main study tasks: * Participants will be treated with either GGA or placebo for 13 weeks. After this they will have a break (wash-out) period for 6 weeks and then cross over to the other study arm. * Cardiac function will be measured using echocardiogram in all participants * Renal measurements and endothelial measurements will be performed on the participants. * Participants will perform a 5 minute walking distance test for functional capacity. * Participants will fill out questionnaires to score signs & symptoms. Researchers will compare the patients to themselves to see if the drug improves diastolic- and endothelial function.

Interventions

DIAGNOSTIC_TESTIohexol measurement

Invasive renal hemodynamic measurement of mGFR through the administration of Iohexol.

DRUGGeranylgeranylacetone (GGA)

13 weeks of treatment with GGA/placebo orally, followed by a wash-out period of 6 weeks, then reversal of the treatment arms.

DIAGNOSTIC_TESTEchocardiography

The investigators will perform echocardiography to find changes in cardiac function.

DIAGNOSTIC_TEST6-minute walking distance test

6 minute walking distance test to compare exercise tolerance in participants.

DIAGNOSTIC_TESTEndoPAT

Use of EndoPAT to measure endothelial function.

DIAGNOSTIC_TESTPara-amino Hippuric Acid test

PAH-measurement to measure ERPF.

DIAGNOSTIC_TESTElectrocardiogram

12-lead Electrocardiogram
