Background Thrombolytic therapy is currently the only FDA-approved treatment for acute ischemic stroke. Hence, early diagnosis and risk stratification is of great importance in management. Objective The aim of this work was to study serum level of matrix metalloproteinase-9 (MMP-9) within 24 h of acute ischemic stroke onset and its relation with clinical severity. Patients and methods Thirty patients with acute ischemic stroke were subjected to measurement of serum MMP-9 within 24 h of stroke onset and clinical assessment of stroke severity. Thirty healthy volunteers of matched age and sex were included as controls. Results Fifteen male and 15 female patients with a mean age of 61 ± 7.11 years were studied. The mean National Institutes of Health Stroke Scale (NIHSS) score on admission was 11.17 ± 4.76. The mean serum level of MMP-9 in patients was 998.8 ± 154.72 ng/ml, which was significantly higher compared with the serum level of MMP-9 in controls (P = 0.003). The mean NIHSS of patients with normal serum level of MMP-9 was less than the mean NIHSS in patients with high MMP-9 serum levels (P = 0.003). There was a significant positive correlation between serum level of MMP-9 and NIHSS score (r = 0.5; P = 0.005) even after adjustment of other variables )age, sex, diabetes, hypertension, fasting blood sugar, uric acid, serum triglycerides, serum cholesterol, and right and left carotid intima media thickness( (r = 0.48; P = 0.032). Conclusion Serum MMP-9 level was found to be high in acute ischemic stroke patients and correlated with clinical stroke severity.
