Despite the best medical management, many patients with peripheral artery disease (PAD) who undergo lower extremity endovascular revascularization experience adverse cardiovascular outcomes and postoperative complications that may increase the risk of acute limb ischemia or amputation. There are no clear molecular associations that could explain the differences in outcomes after endovascular therapy in patients with PAD. The variable outcomes following endovascular therapy may depend, at least in part, on the profile of cytokines involved in inflammatory and atherosclerotic processes. The goal of this observational study is to evaluate the potential use of circulating IL-1, IL-6, TNF-alpha, C reactive protein, HMGB-1, osteoprotegerin, sortilin and omentin-1 levels as biomarkers of major adverse limb events (MALE) and major adverse cardiovascular events (MACE) in diabetic patients with PAD and chronic limb-threatening ischemia (CLTI) requiring a procedure of endovascular revascularization. The main questions it aims to answer are: * association between serum levels of IL-1, IL-6, TNF-alpha, C reactive protein, HMGB-1, osteoprotegerin, sortilin and omentin-1 at baseline and major adverse limb events (MALE) after lower extremity revascularization. * association between serum levels of IL-1, IL-6, TNF-alpha, C reactive protein, HMGB-1, osteoprotegerin, sortilin and omentin-1 at baseline and major adverse cardiovascular events (MACE) after lower extremity revascularization. Diabetic patients with CLTI requiring lower extremity endovascular revascularization will undergo blood sampling for the dosage of circulating IL-1, IL-6, TNF-alpha, C reactive protein, HMGB-1, osteoprotegerin, sortilin and omentin-1 before the endovascular procedure. Incidence of MALE and MACE will be collected in a 12-months follow-up and will be associated with IL-1, IL-6, TNF-alpha, C reactive protein, HMGB-1, osteoprotegerin, sortilin and omentin-1 serum levels.
