title: [Prevalence of cardiomyopathy in HIV infection: prospective study on 158 HIV patients].
abstract: BACKGROUND
  There is evidence that the human immunodeficiency virus (HIV) may affect the heart and left ventricular dysfunction appears to be common.
  
  
  OBJECTIVE
  This was the first study in Morocco to investigate the frequency of cardiomyopathy in patients infected with HIV.
  
  
  METHODS
  We made a prospective echocardiographic study of 158 patients starting in September 2004 (88 men and 70 women, mean age 34 [5.4] years) with positive HIV serology and a clinical diagnosis of HIV infection according to CDC criteria and 80 seronegative control subjects. Patients were classified as AIDS group (90 patients) and HIV group (+) (68 patients) and HIV (-) (80 subjects).
  
  
  RESULTS
  Twenty-eight out of 156 (17.7%) cases of cardiomyopathy were found, distributed in 24 out of 90 (26.6%) in the AIDS group and four out of 68 (2.8%) in the HIV+group (p<0.01) and none in the HIV (-) group. Left ventricular diastolic dysfunction was noted among 88 out of 158 (55.7%) infected patients. There was a significant increase of cardiomyopathy in patients with HIV infection and decreased CD4 (less than 100 per millimetre cube; n=16 [57%]) compared to those with CD4 between 100 and 200 per millimetre cube; n=6 (21.42%) (p=0.03).
  
  
  CONCLUSIONS
  Echocardiography was a useful technique for the early detection of cardiac dysfunction in asymptomatic HIV positive carriers and AIDS patients. The frequency is related to HIV infection stage and CD4+ counts. Left ventricular diastolic dysfunction can precede systolic dysfunction and may be a useful technique for the early detection of cardiac dysfunction.
