All trials for Chronic Myeloproliferative Disorders All trials of Echocardiography
Pulmonary hypertension (PH) is a complex condition that may be related to many clinical conditions. It is a serious disorder with a high morbidity and mortality rates. PH is classified into five groups according to clinical characteristics, pathological findings, hemodynamic characteristics and treatment response (Galie N, et al., 2016). These five groups include pulmonary arterial hypertension, PH due to left sided heart disease, PH due to lung disease and/or hypoxia, chronic thromboembolic pulmonary hypertension, or other pulmonary arterial obstruction and PH with unclear and/or multifactorial mechanisms (Simonneau G, et al., 2013).
PH is a major complication of several hematologic disorders including myeloproliferative neoplasms (MPNs). MPNs are a group of diseases characterized by uncontrolled proliferation of at least one myeloid series due to an abnormal hematopoietic cell clone. There are different types of MPNs including polycythemia vera (PV), essential thrombocythemia (ET), primary myelofibrosis (PMF) \& chronic myeloid leukemia ( CML). Myeloproliferative neoplasms (MPNs) are included in group 5 PH (Arber DA, et al., 2016).
This study will analyze the clinical and laboratory data of MPNs patients and correlate them with development of PH in these patients aiming to identify parameters that can predict PH in MPNs patients and thus, identifying MPNs patients at highest risk for PH who require close monitoring \& screening for PH hoping that early detection and management of PH in MPNs patients can improve morbidity, prognosis and survival in those patients

| MPNs patients who have echocardiographic probability of PH. | Diagnostic Test: Echocardiography | ||
| MPNs patients who do not have echocardiographic probability of PH | Diagnostic Test: Echocardiography |
