Abstract: © 2016 Canadian Cardiovascular Society Iron overload cardiomyopathy occurs in a rare primary form (ie, hemochromatosis) and a very common secondary form in a host of hemoglobinopathies (eg, thalassemia, sickle cell anemia) of substantial and growing global prevalence, which have transformed iron overload cardiomyopathy into a worldwide epidemic. Intracellular calcium ([Ca2+]i) is known to be a critical regulator of myocardial function, in which it plays a key role in maintaining cardiac excitation-contraction coupling. It has been proposed that a disturbance in cardiac calcium regulation is a major contributor to left ventricular dysfunction in iron overload cardiomyopathy. This review comprehensively summarizes reports concerned with the effects of iron overload on cardiac calcium regulation, including alteration in the intracellular calcium level, voltage-gated calcium channel function, and calcium cycling protein activity. Consistent reports, as well as inconsistent findings, from both in vitro and in vivo studies, are presented and discussed. The understanding of these mechanisms has provided important new pathophysiological insights and has led to the development of novel therapeutic and preventive strategies for patients with iron overload cardiomyopathy that are currently in clinical trials.
