HIV-uninfected children born to HIV+ women have low level heart problems at birth which may predispose them to heart failure, arrythmias and heart attack later in life. The impact of these heart problems on future heart health is unclear as it is unknown if heart problems in these children persist, worsen or resolve in pre-pubescence. The objective of this study is to characterize heart function in HIV-negative pre-pubertal children born to HIV+ women and exposed to HIV and HAART in utero and compare them to age and gender matched healthy children born to HIV-negative women. Through this objective we will determine if heart problems in HIV-negative children born to HIV+ women and exposed to HAART in utero persists, worsens, or resolves during pre-pubescence.
