Influence of matrix metalloproteinase 9 variant rs17576 on ischemic stroke risk and severity in acute coronary syndrome.

Background: Ischemic injury is a common mechanism in both ischemic stroke (IS) and acute coronary syndrome (ACS). Matrix metalloproteinase 9 (MMP-9), an endopeptidase that degrades extracellular matrix, is important in the pathogenesis of IS. The purpose of this study is to evaluate the association between the SNP rs17576 in MMP-9 gene with (1) the risk and severity of acute ischemic stroke in Saudi Arab individuals with recent acute coronary syndrome, and (2) the risk of acute coronary syndrome in Saudi Arab individuals without ischemic stroke.
