Abstract
We 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 than in baseline group. Moreover higher levels of MMP-9 and decreased TIMP was reported to be associated with the risk of restenosis. This systematic review shows that available evidence regarding the dynamics of MMP-9 and TIMP levels may be a predictor of cerebrovascular events in both symptomatic and asymptomatic carotid stenosis in patients treated with stenting or endarterectomy.
