Metabolic syndrome and hyperhomocysteinemia in patients with deep vein thrombosis: a case-control study

We evaluated the prevalence of the metabolic syndrome (MS) and of hyperhomocysteinemia in patients with unprovoked deep vein thrombosis (DVT) and in controls. The MS and hyperhomocysteinemia were significantly more prevalent in DVT patients than in controls. However, only the MS resulted independently associated with DVT, and the coexistence of both risk factors did not increase the magnitude of the association.
