This project will be conducted in collaboration between Florida Heart Center and Associates in infectious Disease - two communities based infectious disease and cardiology practices. We will identify all the HIV positive patients seen within a 1 month timeframe at the infectious disease office. These patients will then be filtered by our exclusion/inclusion criteria. After obtaining informed consent, we will draw blood from each patient to gather lab values such as A1C, cholesterol, inflammatory markers, and other markers associated with coronary artery disease. Each enrolled patient will then schedule and receive a 64 slide coronary CTA at Florida Heart Center. The results of the CTA scans will be categorized in mild, moderate, and severe coronary artery disease. The data, then, will consist of the parameters measured on blood work, and the results of the coronary CTA.
