Chagas Heart Disease: The Evolution of the Disease and its Complementary Exams

As in many areas of Medicine, the scenario that harbors Chagas Disease(CD) has changed substantially. For approximately 50 years, as a Resident Physician, I was on duty at the Emergency Department of the Hospital de Clínicas of the Universidade Federal do Paraná and routinely attended, on each shift, one or more cases of patients with clear Congestive Heart Failure, anasarca, electrocardiogram with conduction disorders and multiple arrhythmias, chest X-ray with cardiomegaly and laboratory diagnosis of CD. There was no echocardiogram. Today this is an unusual situation; when it occurs, students are invited to see an exuberant picture of Chagas’ heart disease (CHD), which appears every semester.

In epidemiological surveys, similar findings are observed. In 1984, the prevalence of CD in the State of Paraná, Brazil, was 4% of the population. In 2020, estimates of the prevalence of infections by Trypanosoma cruzi ranged from 1.02% to 2.4% in Brazil. In the period 1975/83, among 291 municipalities in Paraná, 90 (30.9%) had triatomine insects infected by T. cruzi, while in 1990, these were found in only 4 municipalities (1.4%), with subsequent eradication of vector contamination. Vector control strategies have led to a substantial decline in the global prevalence of the disease, estimated at 18 million in 1990 and 6 million in 2018.

Cardiac Magnetic Resonance in the Assessment of Chagas Disease and its Complications

Ariane Binoti Pacheco et al. Rodrigo de Jesus Louzeiro Melo Carlos Eduardo Rochitte

Abstract

The well-known occurrence of Chagas disease in endemic areas has become a worldwide problem, and cardiac magnetic resonance allows the early detection of cardiac involvement and complications of this disease. Cardiac magnetic resonance is a useful tool in all phases of Chagas disease, and new promising techniques using T1 mapping and extracellular volume measurements are able to detect cardiac involvement even earlier than conventional techniques.
