Brief Summary:

The principal aim of the study is to determine the effects n3-PUFA on top of standard therapy on surrogate markers of disease severity and/or prognosis in patients with PAD.

Treatment duration will be 3 months, final follow-up is planned at 6 months after inclusion.

Primary outcome parameter is endothelial function assessed by flow-mediated vasodilation using brachial artery ultrasound.

Secondary outcome measures comprise maximum and pain-free treadmill walking distance, pulse wave velocity, whole blood viscosity, platelet activation and plasma markers of inflammation.

Arm Intervention/treatment
Active Comparator: Omacor Drug: OMACOR
4 capsules OMACOR 1g per day

Placebo Comparator: Placebo Drug: Placebo

Primary Outcome Measures :
  1. change from baseline endothelial function to 3 months [ Time Frame: baseline, 3 months ]
    measured by flow mediated vasodilation

Secondary Outcome Measures :
  1. change from baseline endothelial function to six months [ Time Frame: baseline, 6 months (3 months after treatment cessation) ]
  2. change of walking distance (maximum/pain-free)from baseline to three months and six months [ Time Frame: baseline, 3, 6 months ]
  3. change of inflammatory markers from baseline to one, three and six months [ Time Frame: baseline, 1, 3, 6 months ]
  4. change of pulse wave velocity from baseline to one, three and six months [ Time Frame: baseline, 1, 3, 6 months ]
  5. bleeding events [ Time Frame: 1, 3, 6 months ]
  6. liver enzymes changes [ Time Frame: baseline, 1,3,6 months ]
  7. change of platelet activation from baseline to one, three and six months [ Time Frame: baseline, 1, 3, 6 months ]
