We present a case of pulmonary arterial hypertension (PAH), which is potentially related to treatment with dasatinib (Sprycel®). A 61-year-old woman, who had been treated with dasatinib for 27 months for chronic myeloid leukemia (CML), visited our hospital complaining of dyspnea. In right heart catheterization, her mean pulmonary arterial pressure was 35 mmHg. After other possible etiologies to cause PAH were excluded, the patient was diagnosed as a dasatinib-related PAH. As notified by U.S. Food and Drug Administration (FDA) in October 2011, we recommend routine cardiopulmonary evaluation before and during treatment with dasatinib in CML patients in terms of the adverse effects of PAH.
