Background: Increased serum MMP-9 level is known to be biomarker of atherosclerotic events and risk of cerebrovascular disease. Risk factors for acute ischemic stroke are known to be related to serum MMP-9 level. The genetic variant of MMP-9 rs3918242 is known to have a role in serum MMP-9 level. The aim of the study is to determine the role of MMP-9 rs 3918242 genetic variant in association between MMP-9 serum level with risk factors of acute ischemic stroke. Methods: This was a cross-sectional study with an observational analytic design. 62 subjects of acute ischemic stroke treated at Dr. Kariadi Hospital Semarang from October 2018 to February 2019 were involved in this study. Statistical analysis was assessed by the bivariate test and followed by a logistic regression test. Results: From 62 subjects in this study, 45 (72.6%) had high serum MMP-9 level. The association between serum MMP-9 level with risk factors of acute ischemic stroke was statistically significant in hypertension, diabetes mellitus, dyslipidemia, obesity, and hyperuricemia. There is a positive correlation of serum MMP-9 level with a number of acute ischemic stroke factors. In multivariate analysis, the most influential variables were obesity and hyperuricemia. CC Genetic Variant has a role in the association between serum MMP-9 level with risk factors of acute ischemic stroke, which are hypertension, diabetes mellitus, dyslipidemia, obesity, and hyperuricemia. Meanwhile, CT genetic variants only play a role in the association of serum MMP-9 levels with obesity and hyperuricemia as the risk factors for acute ischemic stroke, Conclusion: CC genetic variants with high serum MMP-9 levels are associated with more acute ischemic stroke risk factors than CT genetic variants with high MMP-9 serum levels. Therefore, CC genetic variants have the potential to pose more risk of acute ischemic stroke.
