Key result
Transfusion-dependent thalassemia is linked to ~19% DCM, while non-dependent patients primarily have pulmonary hypertension.
Why the study?
Cardiac complications remain the primary cause of mortality and major morbidity in thalassemia patients, necessitating assessment of prevalence and differences between TDT and NTDT patients.
Population
70 TDT and 50 NTDT beta thalassemia patients
Comparison
Cardiac involvement in TDT vs NTDT beta thalassemia patients
Design
Prospective observational study

Supports subtype-specific cardiac surveillance in thalassemia; hypothesis-generating for prospective outcome studies.
Observational (n=120)
In beta-thalassemia patients, dilated cardiomyopathy is the prevailing cardiac complication in transfusion-dependent patients, while pulmonary hypertension is more common in non-transfusion dependent patients.
Nameq et al. (2020) conducted an observational in beta thalassemia (n=120). Transfusion-dependent thalassemia (TDT) vs. Non-transfusion dependent thalassemia (NTDT) was evaluated on Prevalence of cardiac involvement. Transfusion-dependent thalassemia was associated with dilated cardiomyopathy (18.6%), while pulmonary hypertension was the main cardiac complication in non-transfusion dependent patients (30%).
