The Prevalence of Pulmonary Hypertension in Beta-Thalassemia Patients in Hormozgan Province: A Cross-sectional Study

Abstract

Background: Pulmonary hypertension (PH) is associated with an increased risk of cardiac failure among asymptomatic patients with beta-thalassemia. This study aimed to determine the prevalence of PH and associated risk factors in patients with beta-thalassemia major (TM) and beta-thalassemia intermedia (TI) in Hormozgan province, Iran. Materials and Methods: Eighty-nine patients, including 65 TM and 24 TI, were enrolled in this cross-sectional study. The data regarding the gender, age, history of splenectomy, and type of chelating therapy were collected, and then hematocrit, hemoglobin (Hb), and serum ferritin levels were determined. Doppler echocardiography was performed for patients, and tricuspid regurgitation jet velocity (TRV)≥2.5 m/s was used to screen PH. Eventually, the data were analyzed using SPSS. Results: The prevalence of TRV≥2.5 m/s was 21.3% in all patients, indicating that it was not significantly different between patients with TM (21.8%) and TI (20.8%). There was a significant association between the prevalence of PH and the male gender. Based on the results, TRV≥2.5 m/s was observed in both children and adults. No significant association was detected between Hb, serum ferritin levels, and splenectomy with PH prevalence. Conclusion: The findings revealed that PH is common in both children and adult patients with TM and TI in our population and should be considered to choose the optimal treatment of patients with TM and TI.
