Femoral artery wall morphology, hemostatic factors and intermittent claudication: ultrasound study in men at high and low risk for atherosclerotic disease.

The aim of this study was to examine whether there was a relationship between ultrasound-assessed morphology of the femoral artery wall and hemostatic factors, and whether these factors were associated with intermittent claudication. One hundred and thirty men at high cardiovascular risk and 51 men at low risk were examined. The subjects (high- and low-risk) with moderate/large plaque (n = 96) had higher fibrinogen, thrombin/antithrombin complex and von Willebrand factor, compared to subjects with small/no plaque. The maximum intima-media thickness of the femoral artery was significantly associated with fibrinogen. These associations were independent of current smoking habits. Clinical atherosclerosis was associated with fibrinogen, von Willebrand factor, thrombin/antithrombin complex, plasminogen activator inhibitor activity, mean and maximum intima-media thickness and plaque status of the femoral artery. In conclusion, fibrinogen, von Willebrand factor and thrombin/antithrombin complex were related to plaque occurrence in the femoral artery. Clinical atherosclerosis was associated with fibrinogen, von Willebrand factor, thrombin/antithrombin complex and plasminogen activator inhibitor activity.
