Objective-To describe the 5-year cumulative incidence of cardiac dysfunction in human immunodeficiency virus (HIV)-infected children.Study design-We used a prospective cohort design, enrolling children at 10 hospitals. Group I included 205 vertically HIV-infected children enrolled at a median age of 1.9 years. Group II consisted of 600 HIV-exposed children enrolled prenatally or as neonates, of whom 93 were ultimately HIV-infected. The main outcome measures were echocardiographic indexes of left ventricular dysfunction.Results-In group I, the 5-year cumulative incidence of left ventricular fractional shortening ≤25% was 28.0%. The 5-year incidence of left ventricular end-diastolic dilatation was 21.7%, and heart failure and/or the use of cardiac medications 28.8%. The mortality rate 1 year after the diagnosis of heart failure was 52.5% [95% CI,. Within group II, the 5-year cumulative incidence of decreased fractional shortening was 10.7% in the HIV-infected compared with 3.1% in the HIV-uninfected children (P = .01). Left ventricular dilation, heart failure, and/or the use of cardiac medications were more common in infected compared with uninfected children.

We recommend that HIV-infected children undergo routine echocardiographic surveillance for cardiac abnormalities.Human immunodeficiency virus (HIV) infection continues to be an important cause of morbidity and mortality in children. We designed the Pediatric pulmonary and cardiovascular complications of vertically transmitted human immunodeficiency virus infection (P 2 C 2 ) HIV study to determine the incidence of heart and lung abnormalities in HIV-infected children. This study began in 1990 and data collection continued through January 1997. Our group previously reported that over the first 2 years of observation, 10% of HIV-infected children either had congestive heart failure (CHF) or required treatment with cardiac medications or both. 1 In addition, 20% of HIV-infected children had cardiac dilation or dysfunction. 1 We also reported that over the entire 6-year observation period of our study, cardiac abnormalities were the underlying cause of HIV-related death in 11 (11.8%) of 93 children and were a contributing cause in an additional 22%. 2 Furthermore, baseline cardiac dysfunction was a risk factor for death independent of CD4 count, wasting, and other predictors of death. 3Our previous report detailing the incidence of cardiac complications in HIV-infected children was limited to the first 2 years of observation in the P 2 C 2 HIV study. 1 The majority of other published studies of cardiac dysfunction in HIV-infected children have been crosssectional or short-term descriptions.
