Brief summary
The study aims to investigate short-term physiological and biochemical inflammatory and cardiocirculatory biomarker kinetics in heart failure patients, using the DIGIPREDICT Physiopatch device - an investigational device that allows non-invasive realtime single-lead ECG registration and bioimpedance measurement as well as spotcheck photoplethysmography -, and standard laboratory methods, respectively.
