Heart failure (HF) is a significant cause of death and the leading cause of hospitalization in patients over 65 years of age. Congestion is the main source of symptoms and the leading cause of hospitalization for HF. Furthermore, congestive signs identified in asymptomatic patients are associated with the risk of developing symptomatic HF. The literature supports a multi-modality / integrative evaluation of congestion, combining clinical examination, laboratory results and ultrasound evaluation.

The main objective of the CHF-COV study is to identify congestion markers (clinical, biological and ultrasound) quantified during a consultation or day hospitalization for the monitoring of chronic HF that are associated with the risk of all-cause death or hospitalization for acute HF within 24 months after day hospitalization.
