New Incremental Model for Predicting Mortality in Pre-Capillary Pulmonary Hypertension.

Background: In pulmonary hypertension (PH), the identification of easily obtainable prognostic markers associated with right ventricular (RV) dysfunction and survival is needed.

Objective: To evaluate the association of red cell distribution width (RDW) with clinical, echocardiographic parameters and survival in patients with pre-capillary PH, with the development of a mortality prediction model.

Methods: Observational, longitudinal, and prospective study conducted from May 2019 to December 2022.
