Cardiac involvement in beta-thalassaemia: current treatment strategies

Area of Science:

• Cardiology
• Hematology
• Genetics

Background:

• Heart disease is the leading cause of mortality in thalassemia major patients.
• Cardiac complications include myocardial dysfunction, arrhythmias, and pulmonary hypertension.
• Iron overload from transfusions is a major cause, but other mechanisms are also significant.

Purpose of the Study:

• To review the pathogenesis of cardiac involvement in beta-thalassemia major.
• To discuss advances in managing cardiac complications.
• To explore future prospects for patient care.

Main Methods:

• Literature review of pathogenesis, management, and outcomes.
• Analysis of current treatment strategies for cardiac complications.
• Discussion of emerging therapies and research directions.

Main Results:

• Cardiac siderosis is a key factor in myocardial dysfunction in transfusion-dependent patients.
• Non-transfusion-dependent mechanisms of cardiac damage are increasingly recognized.
• The prevalence and predictors of cardiac issues in post-HSCT patients are largely unknown.

Conclusions:

• Comprehensive management of iron overload is crucial for preventing cardiac complications.
• Further research is needed to understand and manage cardiac risks, especially in specific patient groups like those post-HSCT.
• Advances in treatment offer hope for improving long-term outcomes in thalassemia major.
