Screening for Heart Failure Using a Multimodal Wearable Device

Heart Failure (HF) is a multi-faceted and life-threatening syndrome characterized by significant morbidity and mortality, poor functional capacity and quality of life, and high costs. Logistic and economic difficulties prove screening for HF challenging for some populations, such as people with reduced mobility and the elderly. Sensor technologies and data processing algorithms, including artificial intelligence, represent an opportunity to systematically identify patients suffering from HF as a complementary tool for echocardiography. The ability to compute digital biomarkers using complex models from wearable data requires identifying the key parameters that are associated with the presence of HF. A multisensorial wearable device can be utilized to develop digital biomarkers for population-based screening of HF. The present study aims to evaluate the best signals from a wearable device to identify digital signals (aka digital biomarkers) that are most associated with HF, including all ejection fraction types.

For this study, investigators will recruit 27 participants with HF and 27 without HF. The primary objective of this study is to analyze the key physiological parameters recorded from the platform devices that can develop a digital biomarker for the presence of prevalent HF and its markers like NTproBNP, KCCQ, and 6MWD
