Main study: A contactless non-intrusive ambient sensor system including infrared motion sensors combined with a contactless Emfit bed sensor will be installed in the home of single living study patients by using a commercially available System (Domo Health®, Lausanne) after informed consent has been obtained. Sensor data are prospectively followed over 3-6 months for predefined indicators of health deterioration. If indicators for health deterioration are present, patients will be called in to the hospital for cardiology consult by the study team including blood analysis for follow-up of BNP values and if necessary, therapy adaption.

Sensitivity and specificity of a combination of ambient sensor derived digital biomarker for the prediction of brain natriuretic peptide (BNP) increase of ≥ 20% compared to baseline value.

KCCQ scores are scaled from 0 to 100 and frequently summarized in 25-point ranges, where scores represent health status as follows: 0 to 24: very poor to poor; 25 to 49: poor to fair; 50 to 74: fair to good; and 75 to 100: good to excellent.
