Introduction: Atherosclerosis causes coronary artery stenosis in a lot of patients with acute coronary syndrome (ACS). By controlling platelet activity and destroying the extracellular matrix, a group of enzymes known as matrix metalloproteinases (MMPs) contribute to the plaque rupture process that causes ACS. The study aimed to determine whether there was any correlation between the amount of serum MMP-9 and the severity of coronary artery stenosis in ACS patients. Methods: Cross-sectional analytical observational design was employed in this investigation. The research population consisted of ACS patients at the Dr. Zainoel Abidin General Hospital in Banda Aceh, Indonesia. Patients who were included as samples had to satisfy the inclusion and exclusion requirements. This study used analysis of variance (ANOVA) as a bivariate analysis to examine the connection between blood MMP-9 levels and the severity of coronary artery stenosis. The threshold for statistical significance was a p-value≤0.05. Results: This research comprised 40 patients with ACS, of which 14 had STEMI, 11 had NSTEMI, and 15 had unstable angina pectoris (UAP). Eleven individuals had mild coronary artery stenosis, eleven had moderate stenosis, and eighteen had severe stenosis, according to an analysis of the Gensini score. Bivariate analysis revealed no significant relationship between blood MMP-9 levels and the degree of coronary artery stenosis in ACS patients (p-value = 0.434). Conclusions: In patients with ACS at the Dr. Zainoel Abidin General Hospital in Banda Aceh, Indonesia, there was no statistically significant association between serum MMP-9 levels and the degree of coronary artery stenosis, according to this study. © 2023, Sanglah General Hospital.
