Title (EN) SYSTEMS AND METHODS FOR MANAGING HEART FAILURE
(FR) SYSTÈMES ET MÉTHODES POUR LA PRISE EN CHARGE D'UNE INSUFFISANCE CARDIAQUE
Abstract:
(EN) Systems and methods for monitoring and treating patients with heart failure are described. A signal receiver may receive a heart sound (HS) signal and an impedance signal sensed from the patient. A heart sound detector circuit may use at least the received impedance signal to determine a HS detection window, and detect a HS component indicative of cardiac diastolic function from the received HS signal within the HS detection window. The system may include a heart failure detector circuit that may generate a cardiac diastolic function indicator (DFI) using the detected HS component and, in certain examples, may detect worsening heart failure using the generated DFI. The system may include a therapy circuit to deliver or adjust an electrostimulation therapy based on DFI.
(FR) L'invention concerne des systèmes et des méthodes pour la surveillance et le traitement de patients souffrant d'une insuffisance cardiaque. Un récepteur de signal peut recevoir un signal de bruit cardiaque et un signal d'impédance détectés chez le patient. Un circuit de détection de bruit cardiaque peut utiliser au moins le signal d'impédance reçu pour déterminer une fenêtre de détection de bruit cardiaque, et détecter une composante de bruit cardiaque correspondant à la fonction diastolique cardiaque à partir du signal de bruit cardiaque reçu au sein de la fenêtre de détection de bruit cardiaque. Le système peut comprendre un circuit de détection d'insuffisance cardiaque qui peut générer un indicateur de fonction diastolique cardiaque (DFI) à l'aide de la composante de bruit cardiaque détectée et, dans certains exemples, peut détecter une aggravation d'une insuffisance cardiaque à l'aide du DFI généré. Le système peut comprendre un circuit de traitement pour administrer ou ajuster un traitement d'électrostimulation sur la base du DFI.
