Nigerian Children with Acquired Heart Disease: The Experience in Lagos

Abstract

Background: Most of the recent reports on acquired heart diseases (AHDs) among Nigerian children are either retrospective or cover a short period of time with fewer subjects. The last report on AHDs among children in Lagos was about a decade ago; it was, however, not specific to children with AHDs but was part of a report on structural heart diseases among children in Lagos. The present study was carried out to document the prevalence and profile of different AHDs in children and to compare the findings with those previously reported. Methods: We conducted a quantitative, nonexperimental, prospective, and cross-sectional review of all consecutive cases of AHDs diagnosed with echocardiography at the Lagos State University Teaching Hospital between January 2007 and June 2016. Comparisons between the normally distributed quantitative data were made with the Student t test, while the χ² test was applied for the categorical data. Results: The subjects with AHDs were 73 males and 52 females, with a male-to-female ratio of 1.4:1. The children were aged 15 days to 14 years, with a mean of 6.61 ± 4.26 years. Rheumatic heart disease was the most common AHD, documented in a quarter of the children, followed by dilated cardiomyopathy and pericardial effusion in 20.8% and 17.3%, respectively. Less common lesions encountered were Kawasaki disease, mitral valve prolapse, hyperdynamic circulation, and supraventricular tachycardia. Conclusion: Rheumatic heart disease was still the most common AHD in the children in the present study. Dilated cardiomyopathy and pericardial effusion are on the increase as has been reported earlier.
