Relation of myocardial systolic mechanics to serum ferritin level as a prognosticator in thalassemia patients undergoing repeated transfusion.

Introduction: Myocardial iron overload leading to congestive heart failure (HF) or arrhythmias is a recognized complication in thalassemia patients undergoing chronic blood transfusion. The relationship between myocardial iron load, subclinical systolic dysfunction, and clinical events remains less well known.

Materials And Methods: We studied a total of 77 subjects, comprising 37 thalassemia patients (mean age: 24.
