Biventricular diastolic function assessed by Doppler echocardiogram in children vertically infected with human immunodeficiency virus

Objective to determine,by doppler-echocardiography,the frequency of cardiac diastolic dysfunction in asymptomatic and clinically stable pediatric patients with vertical infection by the human immunodeficiency virus (hiv),from the cardiovascular viewpoint. methods this was an observational,prospective,and cross-sectional study,performed at a regional referral clinic for patients with hiv,in a convenience sample of 94 individuals,assessing biventricular diastolic function by doppler-echocardiography,and weight,blood hemoglobin,and percentage of lymphocytes t-cd4+. results fifty patients had diastolic dysfunction. left ventricular dysfunction occurred in 38.7%,and the predominant type of dysfunction was decreased myocardial compliance. right ventricular dysfunction was observed in 29.4% of the sample,and abnormal relaxation was the most prevalent type. simultaneous biventricular dysfunction occurred in 14.1% of the individuals. there was no association between dysfunction and the immune status. conclusions diastolic dysfunction occurred,individually or simultaneously,with no association with immune status; decreased myocardial compliance was predominant in the left ventricle,and abnormal relaxation in the right ventricle. © 2014 sociedade brasileira de pediatria.
