Pulmonary Hypertension and RV Dysfunction in Myeloproliferative Neoplasms

September 17, 2026 updated by: Esraa medhat Ahmed, Assiut University

Clinical and Hematologic Risk Factors of Right Ventricular Dysfunction and Pulmonary Hypertension in Myeloproliferative Neoplasms

This cross-sectional study aims to determine the prevalence of pulmonary hypertension and right ventricular dysfunction in patients with myeloproliferative neoplasms and to identify associated clinical and hematologic factors.

Study Overview

Detailed Description

Myeloproliferative neoplasms (MPNs) are associated with an increased risk of pulmonary hypertension and right ventricular dysfunction. This observational study will include adults with confirmed polycythemia vera, essential thrombocythemia, or primary myelofibrosis.

All participants will undergo clinical assessment, laboratory evaluation, and echocardiography to assess pulmonary artery systolic pressure and right ventricular systolic function (TAPSE, FAC, and tissue Doppler S').

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Prevalence of Pulmonary Hypertension in MPN Patients
Time Frame: Baseline

PASP measured by echocardiography using TR velocity. Pulmonary hypertension defined as PASP greater than 35 mmHg or TR velocity greater than 2.8 m/s. Prevalence will be calculated.

Baseline

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Prevalence of right ventricular dysfunction
Time Frame: Baseline

Proportion of patients with right ventricular dysfunction defined by TAPSE <17 mm, RV fractional area change <35%, or tissue Doppler S' <9.5 cm/s

Baseline
Pulmonary artery systolic pressure
Time Frame: Baseline

Mean estimated pulmonary artery systolic pressure (mmHg) measured by echocardiography

Baseline
Tricuspid annular plane systolic excursion (TAPSE)
Time Frame: Baseline

Mean TAPSE value (mm) measured by echocardiography.

Baseline
Right ventricular fractional area change
Time Frame: Baseline

Mean right ventricular fractional area change (%) measured by echocardiography.
