Abstract

Thirty-six consecutive patients with idiopathic haemochromatosis (IH) were studied by electrocardiography (ECG), polygraphy, M-mode and 2-D echocardiography and Doppler-echocardiography. No significant correlations were found between ECG, PEP/LVET ratio and echocardiographic measurements. Left ventricular (LV) enlargement with impaired LV systolic function was present only in three patients (5.5%), of whom two died during iron-depleting therapy because of cardiovascular complications. Compared with controls, echocardiographic abnormalities were significantly more frequent and marked in subjects with higher iron overload than in those in whom it was lower. Ten patients were studied before and after iron depletion, nine of whom had only mild echocardiographic abnormalities at baseline examination. Significant reduction of end-diastolic thickness of the interventricular septum and LV mass (P less than 0.01 and less than 0.02 respectively) was observed. Also the end-diastolic thickness of the LV posterior wall and the end-systolic diameter of the left atrium reduced although not to a significant degree. The increased thickness of ventricular walls without impairment of LV systolic function is probably the first and still reversible cardiac alteration due to iron deposition in the myocardium. Later, with increasing iron overload, LV function becomes impaired and dilated cardiomyopathy develops. Early diagnosis and treatment of IH cardiopathy is needed before irreversible cardiac damage occurs
