BCR-ABL1-Negative Chronic Myeloproliferative Neoplasms and Pulmonary Hypertension: A Prospective Long-Term Follow-up Study of the Impact of Pulmonary Hypertension on Survival

This prospective study assessed the prevalence of pulmonary hypertension (PHT) related to chronic myeloproliferative neoplasms (CMPNs) and evaluated the impact of PHT on survival during long-term follow-up. In a large group of BCR-ABL1-negative CMPN patients, there was a low prevalence of PHT. The impact of PHT on survival was negligible
