Patients with human immunodeficiency virus (HIV) infection frequently exhibit silent echocardiographic abnormalities, including diastolic dysfunction. These findings suggest a direct cardiac impact of HIV, particularly in those with compromised immune status.

Area of Science:

  • Cardiology
  • Infectious Diseases
  • Virology

Context:

  • Human immunodeficiency virus (HIV) infection can affect multiple organ systems.
  • Cardiac involvement in HIV is often subclinical in early stages.
  • Echocardiography is a key tool for assessing cardiac structure and function.

Purpose:

  • To determine the prevalence and characteristics of echocardiographic abnormalities in asymptomatic HIV-infected patients.
  • To compare cardiac findings in HIV patients with a healthy control group.
  • To investigate the relationship between immunologic status and cardiac dysfunction in HIV.

Summary:

  • Transthoracic echocardiography revealed abnormal left ventricular relaxation and filling patterns in 125 HIV patients compared to 47 controls.

  • Segmental wall-motion abnormalities (15%) and pericardial effusion (7.2%) were observed in the HIV group.
  • Systolic function and left ventricular dimensions were normal and did not differ significantly between groups.

    • Impact:

    • Silent echocardiographic abnormalities are common in HIV patients, indicating a potential direct myocardial effect of the virus.
    • Diastolic dysfunction in HIV is linked to a poorer immunologic status (lower CD4 counts).
    • Further prospective studies are necessary to understand the clinical prognosis of these asymptomatic cardiac changes.
