Title
(EN) SYSTEMS FOR HEART FAILURE MANAGEMENT
(FR) SYSTÈMES DE PRISE EN CHARGE DE L'INSUFFISANCE CARDIAQUE
Abstract
(EN)
Systems and methods for managing heart failure are described. The system receives physiological information including a first HS signal corresponding to paced ventricular contractions and a second HS signal corresponding to intrinsic ventricular contractions. The system detects worsening heart failure (WHF) using the received physiological information. A signal analyzer circuit can generate a paced HS metric from the first HS signal and a sensed HS metric from the second HS signal, and determine a concordance indicator between the paced and the sensed HS metrics. In response to the detected WHF, the system can use the concordance indicator to generate a therapy adjustment indicator for adjusting electrostimulation therapy, or a worsening cardiac contractility indicator indicating the detected WHF is attributed to degrading myocardial contractility.

La présente invention concerne des systèmes et des procédés de prise en charge de l'insuffisance cardiaque. Le système reçoit des informations physiologiques comprenant un premier signal HS correspondant à des contractions ventriculaires stimulées et un deuxième signal HS correspondant à des contractions ventriculaires intrinsèques. Le système détecte une aggravation d'une insuffisance cardiaque (WHF) au moyen des informations physiologiques reçues. Un circuit analyseur de signal peut générer une grandeur HS stimulée à partir du premier signal HS et une grandeur HS détectée à partir du deuxième signal HS, et déterminer un indicateur de concordance entre les grandeurs HS stimulée et détectée. En réponse à la WHF détectée, le système peut utiliser l'indicateur de concordance pour générer un indicateur d'ajustement de thérapie pour ajuster une thérapie par électrostimulation, ou un indicateur d'aggravation de contractilité cardiaque indiquant que la WHF détectée est attribuée à la dégradation de la contractilité myocardique.
