Prognostic utility of pulse pressure in patients with heart failure with preserved ejection fraction: The RICA Registry.

Background And Aims: The prognostic role of pulse pressure (PP) in heart failure (HF) patients with preserved left ventricular ejection fraction (LVEF) is not well understood. Our aim was to evaluate it in acute and stable HF.

Material And Methods: This work is a retrospective observational study of patients included in the RICA registry between 2008 and 2021.
