Purpose: We aimed to evaluate the impact of intrinsic coagulation factors and hemostatic markers of endothelial dysfunction on complications in patients with atherosclerotic peripheral arterial disease (PAD). Materials and Methods : This prospective study enrolled 120 PAD patients at Fontaine stages 2b to 3 who underwent open surgical, endovascular, or conservative treatment. Coagulation factors (FVIII, FIX, and FXI) and endothelial hemostatic markers, including von Willebrand factor (vWF) activity and level, soluble endothelial protein C receptor, and plasminogen activator inhibitor-1 (PAI-1) levels, were assessed. Results : At 3 months after open bypass grafting, activity of FVIII significantly increased from a median of 175% to 233% (P<0.001). At 3 months after endovascular treatment, the activities of FVIII, FIX, and FXI significantly increased from medians of 157%, 180%, and 156% to 184%, 218%, and 181%, respectively (P<0.05). Six patients with increased FVIII activity developed bypass graft thrombosis. Four patients in the endovascular group and three patients in the conservative treatment group with increased activity of vWF developed myocardial infarction (P=0.049). The subjects who developed restenosis had increased vWF activity (P=0.023) and decreased nitric oxide metabolite levels (P=0.003). Three subjects who received conservative treatment and developed PAD progression at 12 months had increased PAI-1 activity (P=0.028). Conclusion : Patients with advanced PAD had a hypercoagulable status, and performance of open or endovascular revascularization was associated with further hypercoagulability. Increased activity of coagulation factors and altered levels of hemostatic markers of endothelial dysfunction were associated with PAD complications such as graft thrombosis, myocardial infarction, disease progression, and restenosis.
