Chagas disease, caused by Trypanosoma cruzi infection, displays clinical heterogeneity and may be attributable to differential genetic susceptibility. Chronic Chagas cardiomyopathy (CCC) develops only in a subset of T. cruzi-infected individuals and may lead to heart failure that has a worse clinical course and that leads to reduced life expectancy, compared with heart failure of other etiologies. Proinflammatory cytokines play a key role in the development of CCC. Clinical, genetic, and epidemiological studies have linked lymphotoxin-alpha (LTA), a proinflammatory cytokine, to coronary artery disease and myocardial infarction.
