The left ventricular global function index (LVGFI) is a
functional parameter integrating structural as well as
mechanical behaviour. In the MESA study a LVGFI <37% was
shown to be strongly predictive of cardiovascular
events. In the present study, involving patients with
thalassemia major, we found out that different patterns
of myocardial iron overload evaluated by the T2*
multislice technique were more strongly associated with
a LVGFI <37% than with a LV dysfunction. Thus, a
LVGFI<37% could better identify a significant higher
risk of adverse cardiovascular events beyond heart
failure in iron loaded patients.
