Heart failure (HF) is the leading cause of hospitalization ,rehospitalization and mortality for adults over 65 years of age.

This study aimed to assess mortality, and hospitalization rates at 30 days and one year after dicharge of patients with heart failure (HF) with reduced ejection fraction (HFrEF) compared to HF with preserved ejection fraction (HFpEF).

Inclusion Criteria:

• patients admitted to the ED of Monastir with a principal discharge diagnosis code for HF.

Exclusion Criteria:

• Pregnant or breast feeding women. Alteration of consciousness GCS < 15 Critically ill patients needing immediate mechanical hemodynamic of ventilatory support.

Inability to follow instructions or comply with follow-up procedures.

This study included all patients ,with either reduced ejection fraction (HFrEF) defined as LVEF <45% or preserved ejection fraction (HFpEF) defined as LVEF ≥45% ,admitted to the ED of Monastir from 2009 with a principal discharge diagnosis code for HF. The diagnosis of HF categories should rely on the recent transthoracic echocardiographic findings and clinical judgement according to the guidelines.Collected data include clinical features biological markers (BNP or NTpro BNP) and echocardiography findings. The diagnosis of HF categories should rely on the recent transthoracic echocardiographic findings and clinical judgement according to the guidelines. A follow-up period of at least 1 year was required to notice all cause mortality and preferably HF-specific rehospitalization .
