Prevalence of cardiac abnormalities in human immunodeficiency virus infection.
The prevalence of cardiac abnormalities in the spectrum of human immunodeficiency virus (HIV) infection is unknown. Sixty consecutive HIV-infected patients were studied using echocardiograms, electrocardiograms (50 patients) and ambulatory electrocardiographic monitoring (43 patients). Group A (25 patients) were seropositive but pre-AIDS, whereas group B (35 patients) had AIDS and included 24 with an active opportunistic infection (group B1) and 11 without it (group B2). Abnormalities were identified in 32 of 60 patients (53%) and were more frequent in group B (23 of 35, 66%) than in group A (9 of 25, 36%, p less than 0.05) but independent of active opportunistic infection (15 of 24, 62%, in group B1 vs 8 of 11, 73%, in group B2). Echocardiographic abnormalities were identified in 21 of 60 patients (35%), including 7 of 25 (28%) in group A vs 14 of 35 (40%) in group B (difference not significant), and 7 of 24 (29%) in group B1 vs 7 of 11 (64%) in group B2 (difference not significant). Those patients with an absolute CD4 lymphocyte count less than or equal to 100/mm3 had a higher prevalence of echocardiographic abnormalities (12 of 22) than those with CD4 counts greater than 100/mm3 (1 of 14, p less than 0.01). Left ventricular dilation or hypokinesis was identified in 14 of 60 patients (23%), including 4 of 25 (16%) in group A and 10 of 35 (29%) in group B. Electrocardiographic abnormalities were seen in 22 of 50 patients (44%) including 5 of 18 (28%) in group A and 17 of 32 (53%) in group B (difference not significant).(ABSTRACT TRUNCATED AT 250 WORDS)
