Why the study?
Autonomic derangements in Chagas cardiomyopathy have only recently been explored regarding prognostic relevance, and their potential clinical implications for therapeutic purposes remain to be investigated.
Do autonomic function tests identify specific patterns of parasympathetic and sympathetic dysautonomia in patients with Chagas disease and other cardiac conditions?

This review highlights that autonomic impairment in Chagas disease predominantly involves parasympathetic control of heart rate and ventricular adrenergic innervation, which may have prognostic relevance for malignant arrhythmias.

Maciel et al. (2025) conducted a review in Chagas disease, heart failure, hyperthyroidism, mitral valve prolapse, post-cardiac surgery. Autonomic function testing (pharmacological and physiological) vs. Normal controls was evaluated.
