OBJECTIVE Many studies have shown that the C1562T polymorphism in the matrix metalloproteinase (MMP)-9 gene promoter is associated with susceptibility to ischemic stroke (IS), but the association between them remains controversial. Our objective was to explore the relationship between MMP9 C1562T polymorphism and susceptibility to IS in the Chinese population. METHODS We conducted a database search of Wanfang, China Science and Technology Journal database, China National Knowledge Infrastructure, Medline, Embase, PubMed and Springerlink through September 2019. Meta-analysis was performed using Stata15.0 software (StataCorp LP, College Station, TX, USA). RESULTS Thirteen articles were included, including 3,996 patients and 3,815 controls. Among the Chinese population, the results showed no significant difference for the allele model (T vs. C; odds ratio = 1.05, 95%CI: 0.80-1.37). Significant differences were found in the dominant model (TT+TC vs. CC; odds ratio = 2.94, 95%CI: 1.58-5.45) and in the recessive model (TT vs. TC+CC; pooled OR = 0.81, 95%CI: 0.66-0.99). Neither the homozygous model or heterozygous model was significant. CONCLUSIONS We identified a correlation between MMP-9 C1562T polymorphism and IS in the Chinese population; the TT+TC genotype may increase the risk of IS.

D000083242 Ischemic Stroke Stroke due to BRAIN ISCHEMIA resulting in interruption or reduction of blood flow to a part of the brain. When obstruction is due to a BLOOD CLOT formed within in a cerebral blood vessel it is a thrombotic stroke. When obstruction is formed elsewhere and moved to block a cerebral blood vessel (see CEREBRAL EMBOLISM) it is referred to as embolic stroke. Wake-up stroke refers to ischemic stroke occurring during sleep while cryptogenic stroke refers to ischemic stroke of unknown origin.
