REALIsM-HF Pilot Study

The study aims to explore two marketed devices providing a multimarker monitoring including physical activity under real-life conditions in patients with heart failure with preserved ejection fraction (HFpEF) and with heart failure and reduced ejection fraction (HFrEF). It aims to identify potential novel endpoints for future heart failure trials by exploring clinically relevant changes over time and correlations/associations with conventional endpoints such as the six minute walking distance (6MWD), biomarkers and clinical events. Furthermore, it aims to address the challenges and feasibility of implementing device based measurements under real-life conditions.

* For HFrEF only: EF ≤35% assessed by any imaging modality (e.g. echocardiography, cardiac magnetic resonance, cine levocardiography) within 12 months prior to study inclusion
* For HFpEF only: EF ≥45% assessed by any imaging modality (e.g. echocardiography, cardiac magnetic resonance, cine levocardiography) within 12 months prior to study inclusion
* Willingness to wear the DynaPort Move Monitor accelerometer belt and VitalPatch Biosensor during the trial
* Body size allows wearing of the accelerometer belt as confirmed by ability to comfortably fasten the test belt provided for the screening process

Exclusion Criteria

* Inability to comply with planned study procedures or to comply with study protocol requirements; this includes completing required data collection, and attending required follow up study visits
* Hemoglobin \< 8.0 g/dl

* HF is not the primary factor limiting activity within the last three months as indicated by the patient affirming #1, #2 or #3 of the following questionnaire: My ability to be active is most limited by: #1 - Joint, foot, leg, hip or back pain; #2 - Unsteadiness or dizziness impairing daily mobility; #3 - Lifestyle, weather, or I just don't like to be active
* Occurrence of any of the following within 3 months prior to informed consent: Myocardial infarction, Hospitalization for unstable angina, Stroke or transient ischemic attack, Coronary artery bypass graft (CABG), Percutaneous coronary intervention (PCI), Implantation of a cardiac resynchronization therapy device (CRTD), Major surgery (that could interfere with patients' ability to exercise)

* Severe pulmonary disease with any of the following: Requirement of continuous (home) oxygen or History of chronic obstructive pulmonary disease ≥ GOLD III
* Previous (within 30 days or 5 half-lives of the investigational drug, whichever is longer) or concomitant participation in another clinical study with investigational medicinal product(s) or device(s)
* Any condition or therapy, which would make the patient unsuitable for the study, or life expectancy less than 12 months (e.g. active malignancy)
* Heavy alcohol consumption or the use of illicit drugs that, in the opinion of the investigator, may interfere with the patient's safety and / or compliance
* Patients who regularly (\> 1x per week) swim, do water aerobics or go to the sauna, unwilling to omit this activity while needing to wear the study specific medical devices
* Active myocarditis
* Primary hypertrophic cardiomyopathy
