Brief summary

Heart Failure (HF) is a chronic disease that leads to numerous rehospitalisations and affects more than one million people in France. The main objective of this prospective multicentric French study is to describe the annual rate of unplanned hospitalisations for heart failure in a cohort of patients managed by a HeartLogic algorithm. Patients will be included if they fulfill the following requirements 1/Patient implanted with a cardiac defibrillator with or without resynchronisation with the HeartLogic index (RESONATE family, Boston Scientific); 2/History of heart failure (left ventricular ejection fraction ≤40 %; or at least one episode of clinical heart failure with elevated NT pro BNP≥450 ng/L). If a HeartLogic index ≥16 is noticed, the investigator will contact the patient to assess the patient's clinical condition and possibly adjust the heart failure treatment.

Detailed description

Heart Failure (HF) is a chronic disease that leads to numerous rehospitalisations and affects more than one million people in France. The main objective of this prospective multicentric French study is to describe the annual rate of unplanned hospitalisations for heart failure in a cohort of patients managed by a HeartLogic algorithm. 310 patients will be included if they fulfill the following requirements 1/Patient implanted with a cardiac defibrillator with or without resynchronisation with the HeartLogic index (RESONATE family, Boston Scientific); 2/History of heart failure (left ventricular ejection fraction ≤40 %; or at least one episode of clinical heart failure with elevated NT pro BNP≥450 ng/L). The HeartLogic index will be monitored remotely on a weekly basis for 12 months and in case of HeartLogic index ≥16, the local investigator will contact the patient for assessment and adjust HF treatment as necessary. The primary endpoint is unscheduled hospitalization for HF. A blind and independent committee will adjudicate the events. Blood samples will be collected for biobanking, and quality of life will be assessed.

Interventions

DIAGNOSTIC_TESTHeartLogic

In case of HeartLogic index ≥16, the investigator will contact the patient to assess the patient's clinical condition and possibly adjust the heart failure treatment. The management will be standardized across centers according to the Manage-HF protocol.

Hospitalisation for heart failureDuring 12 monthsAnnual rate of unplanned hospitalisations for heart failure

Secondary

MeasureTime frameDescription
Heart failure related mortalityDuring 12 monthsAnnual death rate from heart failure
Unplanned hospitalisation due to ventricular arrhythmiaDuring 12 monthsAnnual rate of unplanned hospitalisation due to ventricular arrhythmia
Unplanned hospitalisations due to atrial arrhythmiaDuring 12 monthsAnnual rate of unplanned hospitalisations due to atrial arrhythmia
Hospitalisation duration related to heart failure, ventricular or atrial arrhythmiaDuring 12 monthsAnnual rate of hospitalisation days related to heart failure, ventricular or atrial arrhythmia
Cardiovascular mortalityDuring 12 monthsAnnual cardiovascular mortality rate
Evolution of the average HeartLogic index each week over a 12-month periodDuring 12 monthsScale title HL index; The lower value is 0 and there is no upper limit; A higher value reflects a higher probability of heart failure
Effect of iSGLT2 on HeartLogic index, atrial arrhythmias and ventricular arrhythmiasDuring 12 monthsDescribe HeartLogic index, atrial arrhythmias and ventricular arrhythmias before and after iSGLT2 medication initiation and between patient treated or not treated with iSGLT2 treatment
Safety of preemptive congestion treatment based on HeartLogic indexDuring 12 monthsCombined diuretic intolerance criteria comprising either an increase in creatinine ≥30%, or an increase or decrease in kaliemia≥30%, or a decrease in natremia ≥30% between the time of the HeartLogic alert and the end of diuretic treatment, or the occurrence of symptomatic hypotension secondary to the initiation or increase in diuretic treatment.
Patient quality of life using the Kansas City Cardiomyopathy QuestionnaireAt baseline and 1 yearScale title : KCCQ; Score between 0 and 100; higher scores reflect better health status
