More Details: INTRODUCTION: Chagas disease is one of the most common diseases in Latin America and heart involvement is the main cause of death. This study aimed to determine differences in tissue Doppler imaging (TDI) parameters in the assessment left and right ventricular function in patients with the indeterminate form of Chagas disease compared to those in healthy controls. METHODS: We compared 194 patients with the indeterminate form of Chagas disease to 72 age-matched healthy individuals. We considered p-values <0.05 to be statistically significant. RESULTS: TDI analysis of the right ventricular (RV) showed lengthened isovolumic relaxation time (IRT) and higher RV index of myocardial performance (RIMP) and left ventricle (LV) index of myocardial performance (LIMP) in the Chagas group than in the control group, indicating RV and LV systolic and diastolic myocardial damage. TDI analysis of the myocardial velocities of the interventricular septum and the lateral wall of the LV also showed a systolic and diastolic myocardial damage. CONCLUSIONS: The study results demonstrated early LV systolic and diastolic myocardial damage in the RV and LV in patients with the indeterminate form of Chagas disease by TDI. These early findings of RV and LV dysfunction may help identify patients who will progress to heart failure during the disease course. TDI should be included in initial patient evaluations because it allows adequate follow-up and treatment.
