HeartLogic™ is an algorithm programmed into implanted devices incorporating several biometric parameters which aims to predict HF episodes. It provides an index which can be monitored remotely, allowing pre-emptive treatment of congestion to prevent acute decompensation. We aim to assess the impact and security of pre-emptive HF management, guided by the HeartLogic™ index.<h4>Methods and results</h4>The HeartLogic™ France Cohort Study is an investigator-initiated, prospective, multi-centre, non-randomized study. Three hundred ten patients with a history of HF (left ventricular ejection fraction ≤40%; or at least one episode of clinical HF with elevated NT-proBNP ≥450 ng/L) and implanted with a cardioverter defibrillator enabling HeartLogic™ index calculation will be included across 10 French centres. The HeartLogic™ index will be monitored remotely for 12 months and in the event of a 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. Secondary endpoints are all-cause mortality, cardiovascular death, HF-related death, unscheduled hospitalizations for ventricular or atrial arrhythmia and HeartLogic™ index evolution over time. Blood samples will be collected for biobanking, and quality of life will be assessed. Finally, the safety of a HeartLogic™-triggered strategy for initiating or increasing diuretic therapy will be assessed. A blind and independent committee will adjudicate the events.<h4>Conclusions</h4>The HeartLogic™ France Cohort Study will provide robust real-world data in a cohort of HF patients managed with the HeartLogic™ algorithm allowing pre-emptive treatment of heart failure exacerbations.ESC heart failure1228-1235https://www.ebi.ac.uk/biostudies/studies/S-EPMC10966255biostudies-literaturePre-emptive treatment of heart failure exacerbations in patients managed with the HeartLogic™ algorithm.PMC10966255Khattar PMinois DJacon PDegand BProbst VBisson AMarijon EGarcia RGueffet JPMansourati VHeartLogic™ France Cohort Study InvestigatorsHimbert CGras MBoveda SLequeux BMansourati JLi APierre BDefaye PGras DGandjbakhch EfalsePre-emptive treatment of heart failure exacerbations in patients managed with the HeartLogic™ algorithm.<h4>Aims</h4>Heart failure (HF) is a chronic disease affecting 64 million people worldwide and places a severe burden on society because of its mortality, numerous re-hospitalizations and associated costs.
