What is the Prevalence of Pulmonary Hypertension in Thalassemic Patients in Guilan? A Retrospective Analytic Study

Abstract

Introduction: Pulmonary hypertension (PH) is quite common among patients with thalassemia, and it can lead to cardiac failure and even death in those patients. Methods: This current cross-sectional study was conducted with 155 patients with β-thalassemia major and thalassemia intermedia referring to Razi Hospital Rasht, Iran in a recent year. All patients underwent echocardiography and the data (including age, sex, thalassemia type, splenectomy history, deferoxamine usage, hydroxyurea usage, hemoglobin, and ferritin level) were collected by a researcher-made checklist. Data analysis was performed using SPSS software. Results: The prevalence of PH was 13.7% in this study. There was a correlation between sex, thalassemia type, deferoxamine usage, and ferritin level with a prevalence of PH. However, there was not a significant relationship between splenectomy history, hydroxyurea usage, and hemoglobin level with PH prevalence (P = 0.187, P = 0.035, and P = 0.178, respectively). Conclusions: The findings of the study represented that the proposed variables can cause and exacerbate cardiac complications and may have a correlation with the disease's side effects. By conducting more studies and designing a more promising interventional study with a higher sample size, using the results of this study and similar studies, a step could be taken to identify patients susceptible to exacerbation of cardiac complications earlier. By treating them, we may be able to increase their chance of survival in the long run.
