BACKGROUND: Matrix metalloproteinases (MMPs) play a significant role in the development and progression of atherosclerotic vascular disease. The purpose of this study was to measure and document the profile of plasma-circulating MMPs in patients with peripheral arterial disease (PAD) undergoing endovascular revascularization.
METHODS: This was a single-center prospective observational study with 80 patients with PAD enrolled. They underwent percutaneous balloon angioplasty and/or angioplasty with stent. Exclusion criteria were acute limb ischemia, active inflammation, wet gangrene, liver disease, end-stage renal failure, and cancer. Patients that underwent open or hybrid (open and endovascular) approach were also excluded from the study. Venous blood samples were taken preoperatively, 24 hr, and 6 months postoperatively. The values of MMP-2, MMP-3, MMP-7, MMP-9, and their inhibitors (tissue inhibitor of metalloproteinases [TIMP]), TIMP-1 and TIMP-2 were measured.
RESULTS: The mean age was 67.1 years, and 66 of them (82.5%) were male. During the clinical follow-up (mean 35.8% months), 12 patients died (16.4%), 15 (20.5%) of them had a major adverse limb event (MALE), and 14 (19.2%) of them had a major adverse cardiovascular event (MACE). There was a statistically significant rise in the values of MMP-2, MMP-3, and MMP-7 at 6 months postoperatively, when compared to the preoperative and 24 hr postoperative values. There was no correlation of MMP and TIMP values with mortality, MALE, and MACE events.
CONCLUSIONS: The present single-center prospective study documented increased circulating levels of MMPs postoperatively in PAD patients undergoing endovascular treatment. Vascular trauma caused by angioplasty could trigger the expression of MMPs and TIMPs, but the absence of any association with clinical complications requires further investigation.
