Objective.  The objective of this article was to compare the left ventricular (LV) systolic function of human immunodeficiency virus (HIV)-infected children with that of healthy controls, determine the prevalence of LV systolic dysfunction in HIV-infected children, and its association with age, stage of disease, and use of zidovudine. Study Design.  This was a comparative cross-sectional descriptive study. Setting.  A University Teaching Hospital in North-Central Nigeria in 2008. Patients.  One hundred fifty HIV-infected children aged 6 weeks-14 years, and an equal number of age- and sex-matched apparently healthy controls. Outcome Measures.  Left ventricular internal dimensions in diastole and systole, LV fractional shortening (FS) and ejection fraction (EF). Left ventricular systolic dysfunction was considered present when FS was <28% or EF was <50%. Results.  Mean LV internal dimensions in diastole was similar in subjects and controls (P= .26). Left ventricular internal dimensions in systole was significantly larger in subjects (2.7 cm, 95% confidence interval [CI] 2.6-2.8 cm) than controls (2.4 cm, 95% CI 2.3-2.5 cm) (P < .001). Mean FS of 27.8% (26.8-28.8%) in subjects was significantly reduced compared with 33.7% (33.1-34.3%) in controls (P < .001), as was EF 61.5% (60.7-62.3%) in subjects and 70.5% (69.7-71.3%) in controls (P < .001). Left ventricular systolic dysfunction was detected in 75 (50.0%, 95% CI 41.7-58.3%) subjects and 5 (3.3%, 95% CI 2.2-6.7) controls (P < .001). Subjects with left ventricular systolic dysfunction were significantly older than those without (P < .001) but did not differ significantly from them with respect to zidovudine therapy or stage of disease. Conclusions.  Left ventricular systolic dysfunction is significantly more frequent in HIV-infected children compared with controls. Left ventricular systolic function in HIV-infected children deteriorates with increasing age and should be serially evaluated in them.
