title: Prevalence of rheumatic heart disease in school children.
abstract: A total number of 8449 school children, in the 5-15 years old, group were examined clinically for evidence of valvular lesions and confirmed by roentgenographic electrocardiographic and echocardiographic findings. Twelve children (0.14%) were suffering from rheumatic heart disease (RHD). The disease was significantly more (p < 0.05) prevalent in the higher age group of 11-15 years as compared to younger children. Boys (0.18%) were affected more than girls (0.09%). The disease was more frequent among children belonging to economically backward group (0.34%) and those living in large families (0.28%). Children living in the slums had significantly (p < 0.05) higher prevalence (0.41%) than those residing in urban areas (0.06%). Only 3 out of 12 (25%) were previously diagnosed cases and remaining were diagnosed for the first time. Past history of rheumatic activity was seen in 41.67% cases. Mitral valve involvement was most frequent, being detected in 10 (83.33%) cases. Majority of cases (58.33%) had the development of symptomatic RHD within 2 years of having suffered from RF. Our study helped to detect the hitherto undiagnosed cases of RHD and showed that its prevalence was higher in older children and those from urban slums.
