Abstract excerpt

Background: Iron overload cardiomyopathy (IOC) is a major determinant of outcomes in hemochromatosis, and conventional echocardiography may miss early myocardial toxicity. Comparative data on primary (PH) versus secondary hemochromatosis (SH) using myocardial work (MW) indices are limited. Methods: We performed a retrospective cross-sectional study of 34 adults (16 PH and 18 SH patients) at a tertiary center....
