CD86 and angina pectoris: We found that the expression of CD86 on PBMCs was elevated at different times in response to LDL in all patients, particularly in the PBMCs from patients with recurrent angina or restenosis at follow-up (24.94% [0.89-91.63%]), compared to the patients without recurrent events (18.40% [5.71-55.10%]).
