Summary
Coronary artery disease (CAD) in human immunodeficiency virus (HIV) patients presents uniquely, often as acute myocardial infarction, independent of CD4 count or opportunistic infections. Histology reveals diffuse arteriopathy with smooth muscle cell proliferation.
Area of Science:
- Cardiology
- Infectious Diseases
- Vascular Biology
Background:
- Coronary artery disease (CAD) is a concern in human immunodeficiency virus (HIV) infection and acquired immunodeficiency syndrome (AIDS).
- Understanding the clinical and angiographic features of HIV-associated CAD is crucial for patient management.
Purpose of the Study:
- To examine the clinical characteristics and angiographic findings of coronary artery disease in patients with HIV/AIDS.
- To identify unique histological features of HIV-associated coronary arteriopathy.
Main Methods:
- Comprehensive literature search of case reports and series on HIV-associated CAD.
- Analysis of clinical data, including demographics, HIV status, CD4 counts, and opportunistic infections.
- Review of angiographic findings and histological characteristics.
Main Results:
- 129 cases identified; 91% males, mean age 42.3 years.
- Acute myocardial infarction was the initial presentation in 77% of patients.
- Histology showed diffuse arteriopathy with smooth muscle cell proliferation and elastic fiber accumulation.
Conclusions:
- Coronary artery disease in HIV/AIDS patients often presents acutely and is independent of CD4 count or opportunistic infections.
- HIV-associated coronary arteriopathy has distinct histological features.
- CAD is a late complication in AIDS progression.
