Intervention / Treatment
Detailed Description
At the start of the study, baseline investigations are performed including assessment of vital signs (blood pressure, heart rate, pulse oxygen saturation), weight, Everest congestion score (consisting of grading of dyspnea, orthopnea, jugular venous distention, rales, edema and fatigue), echocardiography, 24h urine collection, bio-impedance measurements and blood sample analysis with plasma renin and aldosterone Subsequently, a run-in phase of 2 weeks, without intervention, will start. After this run-in period, participants will be reassessed with the same baseline investigations. In addition, a skin biopsy will be performed as well as a blood volume measurement.
In the next phase of the study, salt intake will be increased with 3 grams daily. The salt will be packed in capsules containing 1 g of sodium chloride (NaCl). Patients will be asked to take one capsule with their breakfast, lunch and dinner. Every 2 weeks a follow-up visit is planned.
After 4 weeks of increased salt intake, a new skin biopsy will be taken and a blood volume measurement will be performed.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Heart failure
After a run-in phase of 2 weeks, patients will add 3 g of sodium chloride to every meal, using a NaCl tablet of 1 g.
They will continue the sodium tablet for 4 weeks with a study visit every 2 weeks.
A skin biopsy will be performed before the start of the augmented salt intake and after 4 weeks.

1 gram tid (with every meal)

Active Comparator: Healthy volunteer
After a run-in phase of 2 weeks, volunteers will add 3 g of sodium chloride to every meal, using a NaCl tablet of 1 g.
They will continue the sodium tablet for 4 weeks with a study visit every 2 weeks.A skin biopsy will be performed before the start of the augmented salt intake and after 4 weeks.
