title: A metabolic syndrome independent association between overweight, fibrinolysis impairment and low-grade inflammation in young women with venous thromboembolism.
abstract: It is known that overweight induces fibrinolysis impairment. Since this association has not been completely explored in patients with venous thromboembolism (VTE), we aimed to investigate its presence in young women with VTE and, if present, to determine its extent and the factors that influence it. Thirty women aged 23-49 years in the stable period after VTE were included [19 overweight (body mass index > or = 25) and 11 normal weight]; 52 healthy women (27 overweight and 25 normal weight) served as controls. The euglobulin clot lysis time (ECLT), plasminogen, D-dimer, tissue-type plasminogen activator (t-PA) and plasminogen activator inhibitor-1 (PAI-1) antigen and activity, lipids, fasting plasma glucose, insulin, fibrinogen, interleukin-6 and sedimentation rate were compared between the groups. Overweight patients had more impaired fibrinolysis (delayed ECLT, higher PAI-1 and t-PA antigen) than overweight controls (and normal weight patients). There was no difference in levels of insulin, glucose, fibrinogen and interleukin-6, whereas the sedimentation rate was significantly elevated in overweight patients compared with overweight controls [16 (8-31) versus 8 (5-12), P < 0.05]. The sedimentation rate in overweight patients significantly correlated with body mass index, ECLT, t-PA and PAI-1 antigen, but not with fibrinogen or interleukin-6. We found that overweight VTE patients have more prominent fibrinolysis impairment than predictable from parameters of metabolic syndrome and that is associated with an elevated sedimentation rate. This association could represent a new thrombotic risk profile in overweight women.
