Abstract
Chagas disease (CD) is a severe health problem in countries of Latin America, including Brazil, and is characterised as an acute and chronic infection. CD can affect several organs and cellular tissues, in particular the heart, which can lead to sudden death. This work aimed to review the literature regarding cardiac autonomic function assessed by Heart Rate Variability (HRV) in CD in adult individuals. The search was carried out using the electronic databases PubMed, SciELO, and Web of Science between January 2013 and October 2020. A total of 19 articles were found, of which 14 were included in this review. HRV was demonstrated at baseline conditions, physical exercise, and cardiac rehabilitation. Quantifying CD progression assessed by HRV is an effective method to detect changes in the cardiac autonomic nervous system, even in asymptomatic individuals. Physical exercise can improve autonomic function in CD. Further clinical studies are needed to assess the anatomical-functional, metabolic, and immunological parameters associated with CD evaluated by HRV.
