In the lung lead to pulmonary arterial hypertension which is defined as pulmonary artery systolic pressure ≥25mmHg during rest.


Objectives 

To detect the prevalence of pulmonary hypertension in patients with thalassemia major and how supportive measures affecting outcome of it.


Patients and Methods

A cross sectional study undertaken in Shaheid Hemn Teaching hospital, center for internal medicine diseases with collaboration of thalassemia center inside the hospital; 100 thalassemia major patients who are diagnosed previously by hemoglobin electrophoresis without any other comorbidity taken as a sample and echocardiography done using Phillips CX50 machine of 2009 model; the data then collected and using SPSS v23 for analyzing data.


Results

Study show 53% of thalassemia major has evidence of increased pulmonary artery pressure and only 1% has clinically significant pressure; splenectomy show high risk factor for occurrence of pulmonary hypertension but other supportive measures has no obstacle effect in its occurrence.


Conclusion

Most thalassemia major patients have evidence of pulmonary hypertension at least mild one; and putting splenectomy as a last line of managing them is recommended.
