[Republication of: Evaluation of the implementation of the 2021 guidelines of the European Society of Cardiology for heart failure with reduced ejection fraction in patients aged over 75]. / Republication de : Évaluation de la mise en application des recommandations 2021 de la Société Européenne de Cardiologie pour l'insuffisance cardiaque à fraction d'éjection réduite chez les patients âgés de plus de 75 ans.

INTRODUCTION: Heart failure is a frequent pathology with a poor prognosis which mainly concerns elderly patients. The recommandations concerning the pharmagical treatment in heart failure with LVEF are reduced on randomized trials carried out on a young population. The aim of this work is to evaluate their application on a population aged ≥ 75. MATERIALS AND METHODS: This is a retrospective, bicentric cohort, concerning patients hospitalized between September 1, 2021 and March 31, 2023, at the hospital centers of Troyes and Romilly sur Seine. The primary endpoint was a composite endpoint combining rehospitalisation rate or all-cause death rate at 6 months. RESULTS: A group of 81 patients was included in the study. The average number of treatments is associated with a significant reduction in the rate of hospitalisations ord deaths at 6 months (p = 0,005); as it concerns the level of titration, the analysing comparing the "therapeutic inertia" group and the "current titration/maximum tolerated dose" group did not reveal any significant difference (p = 0,169). CONCLUSION: Our study highlighted the potential positive impact of the application of the latest ESC recommendations concerning first-line drug treatment on the rate of rehospitalisation or death from all causes, in patients with heart failure reduced LVEF aged over 75.
