In patients with beta-thalassemia major, a series of magnetic resonance imaging tests improves early diagnosis and treatment of cardiac iron overload, according to a consensus statement from the American Heart Association published in Circulation: Journal of the American Heart Association. Cardiac MRI can help detect iron accumulation in tissue and allow early intervention before heart failure symptoms are evident, researchers said. The most common cause of mortality in the setting of thalassemia is heart failure, researchers said.
