MMP9 and ischemic stroke: Others, such as D-dimer, lipoprotein-associated phospholipase A2 (Lp-PLA2), fibrinogen, myelin basic protein, neurospecific enolase (NSE) glial fibrillary acidic protein, heart-type fatty acid binding protein (H-FABP), apolipoprotein C I and III (ApoC I and III), von Willebrand factor (vWF), matrix metalloproteinase-9 (MMP-9), monocyte chemotactic protein-1 (MCP-1) and highly sensitive C-reactive protein (hsCRP), are mostly related to risk factors of ischemic stroke and are useless in the early diagnosis [12,13,14].
