HIV-1–uninfected patients with ACS also have altered monocyte subset proportions and increased monocyte expression of TF. Whole blood samples were collected from 10 HIV-1–uninfected ACS patients and 16 patients without AC, but with a similar CVD risk profile (stable CAD controls). Proportions of monocyte subsets (A) and monocytes (B) that express TF were analyzed by flow cytometry. Proportions of intermediate and nonclassic monocytes were increased in ACS patients compared with controls; TF expression was also increased on these cells.
