Large abdominal aortic aneurysms (AAAs) are associated with coagulation abnormalities, which are significantly reduced by low molecular weight heparin (LMWH). Considering anti-inflammatory properties of heparin we verified, whether LMWH influences MMP-2/-9 in AAA patients. The study involved 26 AAA individuals, 10 patients with coagulation abnormalities received LMWH and 16 were a control group. The plasma activity of MMP-2/-9 was measured using zymography. We found that, in addition to the reduction of coagulation abnormalities, LMWH treatment was associated with the decreased MMP-9 but not MMP-2 activity. Therefore, LMWH use could be considered as a valuable pretreatment before an elective aneurysm repair.
