Pulmonary hypertension in patients with sickle cell disease: a longitudinal study

Abstract

(1) PHT, regardless of severity, is associated with an increased risk of death in SCD patients; (2) haemolysis is strongly associated with PHT in SCD; (3) high levels of fetal haemoglobin and hydroxycarbamide therapy may decrease the occurrence of PHT; (4) screening for PHT is indicated for SCD patients in their non-crisis, steady states.
