Early detection of fluid retention in patients with advanced heart failure: a review of a novel multisensory algorithm, HeartLogicTM
Abstract
Heart failure (HF) hospitalisations due to decompensation are associated with shorter life
expectancy and lower quality of life. These hospitalisations pose a significant burden on the patients,
doctors and healthcare resources. Early detection of an upcoming episode of decompensation
may facilitate timely optimisation of the ambulatory medical treatment and thereby prevent heartfailure- related hospitalisations. The HeartLogicTM algorithm combines data from five sensors of cardiac implantable electronic devices into a cumulative index value. It has been developed for early detection of fluid retention in heart failure patients. This review aims to provide an overview of the current literature and experience with the HeartLogicTM algorithm, illustrate how the index can be implemented in daily clinical practice and discuss ongoing studies and potential future developments of interest.
