Key result
Echocardiographic screening of 12,048 Brazilian schoolchildren revealed a 4.5% overall prevalence of rheumatic heart disease, with similar rates across different screening settings (P=0.24).
Why the study?
Does the setting of echocardiographic screening affect the detected prevalence of rheumatic heart disease and consent compliance in schoolchildren?
Cross-Sectional (n=12,048)
Yes

p-value: p=0.24
Echocardiographic screening for rheumatic heart disease in primary care centers achieves higher consent rates than in public schools, while disease prevalence remains high across all settings, including private schools.

Indicates high borderline RHD burden in screened youth; leaves open natural history, progression risk, and screening utility.
Nascimento et al. (2018) conducted a cross-sectional in Rheumatic heart disease (n=12,048). Echocardiographic screening vs. Different screening settings (public schools, private schools, primary care centers) was evaluated on RHD prevalence across screening settings (public schools, private schools, and primary care centers) (p=0.24). Echocardiographic screening of 12,048 Brazilian schoolchildren revealed a 4.5% overall prevalence of rheumatic heart disease, with similar rates across different screening settings (P=0.24).
