Acute myocardial infarction (AMI) in diabetics is much more often than in non-diabetics. MMP-9 activity could ease the formation of atherosclerosis, destabilization and plaque rupture as well as thrombocyte aggregation. The aim of this study is to examine: MMP-9 defining in serum in diabetics; the impact of diabetes mellitus on atherosclerosis and MMP-9 level; relation between serum values of MMP-9 and markers of glycoregulation and lipid status, respectively. Results: The greatest concentration of both total and active MMP-9 serum has been noted in diabetics group with ACS. Both total and active MMP-9 values, in group with diabetes and ACS showed significantly important difference regarding the values in control group. Total and active MMP-9 showed statistically important correlation between the values of glycated hemoglobine A1c (HbA1c) and inverse correlations with values of subfraction HDL3.Active MMP-9 showed statistically important inverse correlation with value of HDL cholesterol. In conclusion: According to the results, it has been thought that active MMP-9 shows a certain degree of atherosclerotic changes on blood vessels better than total MMP-9. MMP-9, active one, could present an early marker of atherosclerosis, especially on coronary blood vessels, in diabetics with type 2. © 2011 Akadémiai Kiadó, Budapest.acute coronary syndrome atherosclerosisdiabetes mellitusMMP-9The importance of defining serum MMP-9 concentration in diabetics as an early marker of the rupture of atheromatous plaque in acute coronary syndrome
