PLA2G7 and metabolic syndrome: Lp-PLA2 activity was significantly increased in MetS subgroups when compared with controls (all P < 0.01), and was higher in patients with carotid plaques than those without plaques (34.10 ± 9.51 umol/min/mL vs. 29.62 ± 8.98 umol/min/mL, P < 0.05) (Table 1, Figure 1).
