ABSTRACT
Monocyte subsets and monocyte-platelet aggregates (MPAs) play important role in atherosclerosis and thrombosis. We aimed to determine their changes in patients with unstable angina (UA). In this cross-sectional case-control study, Global Registry of Acute Coronary Events (GRACE) score was determined in 95 UA patients without elevated troponin level. Thirty age-and-sex matched stable coronary heart disease (CHD) subjects served as control group. The classical (CD14++CD16-, Mon1), the intermediate (CD14++CD16+, Mon2) and the non-classical (CD14+CD16++, Mon3) monocytes, as well as subset-specific MPAs, were measured by flow cytometry. Compared with stable CHD patients, UA patients had increased Mon2 and Mon3 counts (all P < 0.001). For UA subjects, compared with GRACE score-determined low risk patients (GRACE score ≤108, n = 70), intermediate-to-high risk patients (GRACE score >108, n = 25) had higher counts of Mon2 and total MPAs, as well as Mon1- and Mon2-associated MPAs (all P < 0.001). Adjusted binary logistic regression analysis revealed that increased counts of Mon2 subset (for per 5 cells/µL increase, OR 1.186, 95% CI 1.044-1.347, P = 0.009), Mon2 MPAs (for per 5 cells/µL increase, OR 1.228, 95% CI 1.062-1.421, P = 0.006) and total MPAs (for per 5 cells/µL increase, OR 1.072, 95 % CI 1.010-1.137, P = 0.022) independently associated with GRACE score-determined intermediate-to-high risk UA patients. In UA patients with intermediate-to-high risk (determined by GRACE score), counts of Mon2 subset, Mon2-associated MPAs and total MPAs are increased, which are independent of traditional risk factors.
