title: Contribution of environmental toxins in the pathogenesis of idiopathic cardiomyopathies.
abstract: The pathogenesis of idiopathic cardiomyopathies is likely highly complex and remains elusive. Environmental toxins have been hypothesized to possibly cause a subset of cardiomyopathies. Epidemiological, preclinical, and small clinical studies have investigated the role of numerous elements and compounds in the pathogenesis of these myocardial disorders. In this review, we present the evidence implicating elements and environmental compounds in myocardial toxicity, including antimony, cobalt, mercury, aluminum, copper, and acrolein. We discuss their sources, toxic effects, and epidemiology, as well as identify groups at risk for toxic exposure. Through our discussion, we highlight areas where further investigation into the clinical effects of these possible toxins is warranted.
