    Abstract:
    Cardiac abnormalities are frequently reported in patients with acquired immunodeficiency syndrome (AIDS). Much less is known about the true prevalence of cardiac involvement in patients with human immunodeficiency virus (HIV) infection. We prospectively examined 138 consecutive patients with HIV infection including 41 with AIDS, 49 with AIDS-related complex (ARC), 32 with chronic lymphoadenopathy syndrome (LAS) and 16 with asymptomatic HIV infection. Sixty-one patients had opportunistic infection. The prevalence of cardiac involvement progressively increased from patients with HIV infections or LAS (4%) to ARC (14%) to AIDS (37%). "Major" echocardiographic abnormalities (dilated cardiomyopathy and/or infective endocarditis and/or severe pericardial effusion) were identified in 3 patients (2%), "minor" abnormalities (mild pericardial effusion, hypokinesis of the interventricular septum, mild dilatation of the left ventricle in 21 (15%). Electrocardiographic abnormalities unassociated with echo abnormalities or clinical problems were seen in other 11 patients. End diastolic left ventricular dimension (normalized for body surface area) was higher among AIDS respect to pre-AIDS patients (30.1 +/- 7.1 vs 27.6 +/- 7.5; p less than 0.01) and among patients with respect to patients without opportunistic infections (29.5 +/- 6.5 vs 27.5 +/- 2.4; p less than 0.05). Left ventricular shortening fraction was lower in the subgroup with and absolute CD4 lymphocyte count less than 100/mm3 (31 +/- 7 vs 34 +/- 5; p less than 0.055). In conclusion, in a large, unselected group of patients with HIV infection, echocardiogram discloses cardiac abnormalities in 17% of the cases; their clinical relevance is generally low but in selected patients cardiac tamponade and/or dilated cardiomyopathy (secondary to viral myocarditis) may cause death.(ABSTRACT TRUNCATED AT 250 WORDS)
