About this study

Official title: Follow-up of Heart Failure Patients with an Implantable Cardiac Defibrillator Enabled with the HeartLogic Algorithm - HeartLogic France Study

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.

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • HeartLogicDiagnostic test

    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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Hospitalisation for heart failure

    Annual rate of unplanned hospitalisations for heart failure

    Measured: During 12 months

Secondary outcomes (9)
  1. Cardiovascular mortality

    Annual cardiovascular mortality rate

    Measured: During 12 months

  2. Heart failure related mortality

    Annual death rate from heart failure

    Measured: During 12 months

  3. Unplanned hospitalisation due to ventricular arrhythmia

    Annual rate of unplanned hospitalisation due to ventricular arrhythmia

    Measured: During 12 months

  4. Unplanned hospitalisations due to atrial arrhythmia

    Annual rate of unplanned hospitalisations due to atrial arrhythmia

    Measured: During 12 months

  5. Hospitalisation duration related to heart failure, ventricular or atrial arrhythmia

    Annual rate of hospitalisation days related to heart failure, ventricular or atrial arrhythmia

    Measured: During 12 months

  6. Patient quality of life using the Kansas City Cardiomyopathy Questionnaire

    Scale title : KCCQ; Score between 0 and 100; higher scores reflect better health status

    Measured: At baseline and 1 year

  7. Evolution of the average HeartLogic index each week over a 12-month period

    Scale title HL index; The lower value is 0 and there is no upper limit; A higher value reflects a higher probability of heart failure

    Measured: During 12 months

  8. Effect of iSGLT2 on HeartLogic index, atrial arrhythmias and ventricular arrhythmias

    Describe HeartLogic index, atrial arrhythmias and ventricular arrhythmias before and after iSGLT2 medication initiation and between patient treated or not treated with iSGLT2 treatment

    Measured: During 12 months

  9. Safety of preemptive congestion treatment based on HeartLogic index

    Combined "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.

    Measured: During 12 months

Questions about this trial

What is this clinical trial studying?

An observational study of Heart Failure, run by Poitiers University Hospital at 10 sites in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Nov 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Hospitalisation for heart failure (time frame: During 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04619888, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Nov 2024.
