Abstract

Chronic Chagas cardiomyopathy (CCC) is responsible for the disease's greater morbidity and poor prognosis. Although understanding the pathophysiology of CCC and the fundamentals of its clinical management derives from research related to other cardiomyopathies, there are peculiarities that distinguish CCC from the others. CCC is the most fibrous heart disease, and its myocardial involvement is important as it disorganizes or disrupts the extracellular matrix, creating an environment conducive to the formation of arrhythmogenic foci. It is also considered the most arrhythmogenic of the known heart diseases, giving rise to complex arrhythmias, usually associated with varying degrees of stimulus conduction disorders. The central proposal of this review is to describe a possible association between the distribution and degree of myocardial fibrosis and cardiac arrhythmogenicity in patients with Chagas cardiomyopathy, drawing attention to the importance of noninvasive biomarkers for the quantification of myocardial fibrosis.

Keywords: cardiac fibrosis markers; cardiac remodelling; chronic Chagas cardiomyopathy; myocardial fibrosis; ventricular arrhythmic.
