Purpose?Prompt detection of congestion is an essential targetin order to prevent heart failure (HF) related hospitalization,being ambulatory monitoring a promising strategy to do so. Asuccessful non-invasive ambulatory monitoring systemrequires automatic devices for physiological data recording;these data must give information about HF deterioration earlyenough to predict HF-related adverse events. This work aimsto evaluate seven vascular parameters for the ambulatorymonitoring of congestive heart failure patients.Methods?Seven vascular parameters are proposed as indicatorsof HF deterioration. These parameters are obtained using venousocclusion plethysmography; a technique that uses hardware ableof being miniaturized and easily integrated into wearables forambulatory monitoring. The ability of the proposed vascularparameters to detect congestion is evaluated in eight healthyvolunteers and ten congestive heart failure patients with differentcongestion levels?mild, moderate and severe.Results?Most parameters distinguish between healthy vol-unteers and heart failure patients, and some of them presentsignificant differences between volunteers and low levels ofcongestion?mild or moderate.Conclusion?Home monitoring of some of the proposedparameters could detect HF deterioration on its onset andalert to health personnel.
