Objective: To evaluate the prevalence of systolic and diastolic right ventricular (RV) in patients with indeterminate form of Chagas Disease (FDIC) and compare with asymptomatic patients without this condition. Methods: An observational, case-control, descriptive and prevalent study in which 91 patients were divided into 2 groups: group I (normal n = 31) and group II (FIDC normal cardiac n = 61). Were performed 2D Doppler echocardiography in adult patients, applying the criteria assessment of systolic and diastolic RV. Results: The general characteristics of both groups: age (39.73 ± 12.94 vs 45.32 ± 12.36, p = 0.071), weight in kg (71.29 ± 14.91 vs 67.66 ± 12, 37 with p = 0.270), Height in cm (159.24 ± 32.63 vs 156.88 ± 30.56, p = 0.749), ISC (1.77 ± 0.24 vs 1.69 ± 0.19 with p = 0.174) , female sex (24/77, 4% vs 45/73, 8%, p = 0.190) ,heart rate (FC) in bpm ( 71,90 ± 10,43 vs 70,36 ± 9,83), diastolic dimension of LV ( LVDD) em mm ( 46,71± 5,21 vs 46,05 ± 5,22) e ejection fracion of LV ( % por Teicholz) (73,55 ± 6,66 vs 73,56 ± 7,35). The prevalence of RV systolic dysfunction in normal patients and FIDC, using criteria such as FAC <35%, TAM <16mm and systolic S wave velocity <10 cm / s tissue Doppler was: FAC (- / 0.0% vs 1 / 0.6%, p = 0.663), TAM (- / 0.0% vs. - / 0.0%, p = 1.00) and S wave (2/6,4% vs 16/26% with p = 0.016) and a weak correlation (r = 0.31) between age and S wave (p = 0.019). The prevalence of RV global dysfunction in normal patients and FIDC : RIPM of TD(5/16,1% vs 17/27,8% , p=0,099) and RIPM of DP(19/61,3% vs 42/68,8%,p 0,141).The prevalence of RV diastolic dysfunction in groups I and II respectively, according to the criteria established by guideline43: abnormal relaxation AR (- / 0.0% vs 4/ 6.0%, p = 0.187), pseudonormal pattern PP (-/0,0 vs. -/0,0% p = 1,00) and restrictive pattern PR (-/0,0% vs -/0,0%, p = 1,000), with no significant difference in diastolic dysfunction in both groups. Conclusion: The prevalence of RV systolic dysfunction was estimated at 26% (S-wave velocity compared to other variables with p significant, with a weak correlation between the S wave velocity and age) and was not observed statistically significant criteria for diastolic dysfunction between groups.
