Heart failure (HF) represents a major public health challenge due to its increasing prevalence and significant impact on healthcare systems.

The burden of frequent readmissions leads to increased healthcare costs, deterioration in the quality of care, and reduced availability of hospital resources for new patients. It is therefore essential to optimize the management of patients with heart failure from their first visit to the emergency department in order to improve their prognosis and reduce the risk of rehospitalization.

In this context, this study aims to identify the key factors associated with early readmissions (< 30 days) and to propose strategies to improve patient management and follow-up after discharge from hospital.

Inclusion Criteria:

• Patients aged 18 years or older, admitted to the emergency department for confirmed acute heart failure. Hospitalization following admission to the emergency department, with at least one documented post-hospitalization follow-up visit.

Exclusion Criteria:

• Patients under the age of 18 with a primary diagnosis unrelated to heart failure after analysis of their medical records. Patients in palliative care receiving only comfort treatment. No documented post-hospitalization follow-up. Patients who object to the use of their medical data for research purposes.

Adult patients hospitalized for acute heart failure over a period of 6 months.
