“…The anaerobic threshold values used to determine the target heart rate were derived from the baseline cardiopulmonary exercise tests for training sessions conducted between baseline and the 3rd month, and from the 3-month cardiopulmonary exercise test for training sessions between the 3rd and 6th months. For those patients in which anaerobic threshold was not identified during the CPET (n = 13; 43%), training intensity was prescribed according to the Hellerstein formula [HR = (102 + maximum metabolic equivalents achieved)/1.41)] 34 , in which the target heart rate ranged from 70% of maximum heart rate obtained in the CPET to the Hellerstein’s formula percentage in the first month, and from the Hellerstein’s formula percentage to 85% of maximum heart rate in the following months. Borg scale was used as an adjuvant of exercise intensity prescription (targeting 2–4 in CR10 Borg scale).…”

To investigate the effect of an exercise-based cardiac rehabilitation program on the quality of life (QoL) of patients with chronic Chagas cardiomyopathy (CCC). PEACH study was a single-center, superiority randomized clinical trial of exercise training versus no exercise (control). The sample comprised Chagas disease patients with CCC, left ventricular ejection fraction < 45%, without or with HF symptoms (CCC stages B2 or C, respectively). QoL was assessed at baseline, after three months, and at the end of six months of follow-up using the SF-36 questionnaire. Patients randomized for the exercise group (n = 15) performed exercise training (aerobic, strength and stretching exercises) for 60 min, three times a week, during six months. Patients in the control group (n = 15) were not provided with a formal exercise prescription. Both groups received identical nutritional and pharmaceutical counseling during the study. Longitudinal analysis of the effects of exercise training on QoL, considering the interaction term (group × time) to estimate the rate of changes between groups in the outcomes (represented as beta coefficient), was performed using linear mixed models. Models were fitted adjusting for each respective baseline QoL value. There were significant improvements in physical functioning (β = + 10.7; p = 0.02), role limitations due to physical problems (β = + 25.0; p = 0.01), and social functioning (β = + 19.2; p < 0.01) scales during the first three months in the exercise compared to the control group. No significant differences were observed between groups after six months. Exercise-based cardiac rehabilitation provided short-term improvements in the physical and mental aspects of QoL of patients with CCC.Trial registration: ClinicalTrials.gov Identifier: NCT02517632; August 7, 2015.
