MMP-9 activity. MDMs were incubated overnight in medium containing 0.2% fatty-acid-free albumin. The activity of MMP-9 secreted by MDMs was evaluated by the BiotrakTM activity assay system. Data are expressed as mean ± SD and derive from independent cultures obtained from 9 healthy subjects, 9 SA patients, and 18 AMI (9 NSTEMI and 9 STEMI) patients. *P < 0.05 vs. healthy subjects.
