Heart Failure
Conditions
Brief summary
The study will investigate, if inflammatory and cardio-circulatory biochemical biomarkers are detectable in dermal interstitial fluid (dISF) of heart failure patients, and if there are detectable kinetics of these biomarkers during a cardiopulmonary exercise test. For dISF extraction the PELSA System - an investigational device - will be used.
Interventions
DEVICEUse of the PELSA System for dISF extraction
Dermal interstitial fluid will be extracted using the investigational device, for further analysis.
