Cardiac involvement in human immunodeficiency virus-infected patients.
Heart involvement in patients with AIDS has been described in autopsy and clinical series, but the true incidence in HIV-infected patients is not clear. A prospective study was done on 101 unselected HIV-infected patients (71 with AIDS and 30 with pre-AIDS) and 24 healthy controls to assess the prevalence of cardiac abnormalities. Assessment included physical examination, electrocardiogram, two-dimensional echocardiogram, and Doppler studies. At least one abnormality was detected in 41 (40.6%) HIV-infected patients vs. 3 (12.5%) in controls (p = 0.003). Echocardiographic abnormalities were detected in 29 (28.7%) HIV-infected patients and 3 (12.5%) controls (p = 0.04). There were no significant differences in abnormalities on physical examination, electrocardiogram, or Doppler studies. Only six (5.9%) HIV-infected patients had abnormal cardiac findings on physical examination. We found no correlation between HIV staging, CD4 cell count, acute illness, or severity of illness and the presence of cardiac abnormalities. Cardiac abnormalities in HIV-infected patients are more frequent than in healthy controls, but most abnormalities are of no significant clinical consequence.
