Pulmonary hypertension in patients with chronic myeloproliferative disorders

Abstract

Pulmonary hypertension (PH) is a major complication of several haematological disorders. Chronic myeloproliferative diseases (CMPDs) associated with pulmonary hypertension have been included in group five of the clinical classification for pulmonary hypertension, corresponding to pulmonary hypertension for which the aetiology is unclear and/or multifactorial. The aim of this review is to discuss the epidemiology, pathogenic mechanism and treatment approaches of the more common forms of pulmonary hypertension in the context of CMPD’s: chronic thromboembolic pulmonary hypertension, precapillary pulmonary hypertension and drug-induced PH.
