MMP-9 and/or TIMP as predictors of ischaemic stroke in patients with symptomatic and asymptomatic atherosclerotic stenosis of carotid artery treated by stenting or endarterectomy – A review

Publication date: Available online 30 May 2018Source: Neurologia i Neurochirurgia PolskaAuthor(s): Justyna Zielinska-Turek, Małgorzata Dorobek, Grzegorz Turek, Maria Barcikowska-KotowiczAbstractWe still lack an optimal tool to predict ischaemic stroke in patients with symptomatic and asymptomatic carotid stenosis (CS). It has already been shown that patients at increased risk of ischaemic stroke can be identified based on the elevated plasma levels of metalloproteinases (MMPs) and reduced activity tissue inhibitor of metalloproteinase (TIMP). There are few studies presenting the role of MMP-9 and TIMP in ischaemic stroke both in patients with symptomatic and asymptomatic CS treated with stenting or endarterectomy, however we have not found any published review summarizing the role of abovementioned markers. MEDLINE was accessed via Pub Med, and searched for published studies that analyzed MMP-9 and TIMP levels in patients with asymptomatic and symptomatic internal carotid stenosis and/or examined these parameters as potential risk markers for ischaemic stroke. A total of 13 articles documenting the outcomes of patients with symptomatic or asymptomatic carotid stenosis treated by carotid stenting or endarterectomy, were analyzed. Statistically significant differences in the levels of MMP-9 and/or TIMP in patients with symptomatic and asymptomatic CS have been reported. Also the concentrations of MMP-9 and TIMP in CS patients subjected to stenting or endarterectomy were higher...
