Pathology and Pathogenesis of Chagas Heart Disease

Abstract: Chagas heart disease is an inflammatory cardiomyopathy that develops in approximately one-third of people infected with the protozoan parasite Trypanosoma cruzi. One way T. cruzi is transmitted to people is through contact with infected kissing bugs, which are found in much of the Western Hemisphere, including in vast areas of the United States. The epidemiology of T. cruzi and Chagas heart disease and the varied mechanisms leading to myocyte destruction, mononuclear cell infiltration, fibrosis, and edema in t… Show more

“…Chagas cardiomyopathy, caused by Trypanosoma cruzi (T. cruzi or Tc), is a major health concern in Latin America and it is an emerging disease in the United States, Europe, Japan, and other countries [1]. Most of the infected individuals exhibit no clinical symptoms but remain seropositive for their life [2] and serve as reservoir host for maintaining the domestic cycle of Tc transmission. Approximately 30%-40% of the infected individuals slowly develop clinical symptoms that progress from cardiac hypertrophic remodeling (i.e., wall thickening) to dilated cardiomyopathy, ultimately resulting in cardiac arrest and death [3].…”

“…Granulomas não-necrosantes pode estar presente com células gigantes multinucleadas (ROFFÊ et al, 2016). A destruição de nervos parassimpáticos na região epicárdico-mediastinal tem sido documentada, sugerindo um potencial mecanismo para ocorrência de arritmias e morte súbita (MIRANDA et al, 2011;BONNEY et al, 2019).…”

“…Uma vez que a persistência da parasitose e inflamação crônica concomitante, leva a cardiomiopatia chagásica crônica, o tratamento é oferecido à pacientes com a forma indeterminada da doença e a pacientes com doença cardíaca leve a moderada (WHO, 2002;BERN et al, 2007;ANDRADE et al, 2011;PEREZ-MOLINA, MOLINA, 2018).
