E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To study the effect of omega-3 fatty acids on maximal walking distance in patients with intermittent claudication (IC) receiving supervised exercise therapy (SET) compared to patients with IC receiving SET alone. |
Het effect van omega-3 vetzuren onderzoeken op maximale loopafstand in patienten met claudicatio intermittens die behandeld worden met gesuperviseerde looptraining vergeleken met patienten met claudicatio intermittens die alleen gesuperviseerde looptraining krijgen. |
|
E.2.2 | Secondary objectives of the trial |
To study the effect of supplementation of omega-3 fatty acids during 4 weeks on:
- Hemorheological parameters: blood and plasma viscosity, hematocrit and erythrocyte deformability and aggregation
- Pain free walking distance
-Ankle Brachial Index
-- Blood values (Hemoglobin, leucocytes, CRP, total-, HDL- and LDLcholesterol,
triglycerides)-Blood pressure and heart rate
-Walking impairment measured by questionnaire
- ex vivo cytokine production of IL-6, IL-10 and TNF-alpha of whole
blood stimulated with LPS
- Erythrocyte membrane fatty acid composition
- Visceral fat mass
To compare treatment with SET and omega-3 fatty acids to treatment with SET alone by determining the above metioned parameters.

Het effect bestuderen op supplementatie van omega-3 vetzuren
gedurende vier weken op:
-Hemorheolgische parameters: bloed en plasma viscositeit, hematocriet,
erythrocyt deformabiliteit en aggregatie
-Pijn vrije loopafstand
-Enkel arm index
-Andere bloedwaardes: hemoglobine, leukocyten, CRP, totaal cholesterol, HDL, LDL, triglycerides
-Bloeddruk, hartfrequentie
-Beperkingen in lopen, gemeten door middel van een vragenlijst
- ex vivo volbloed cytokine prodcutie van IL-6, TNF-alfa, IL-10 na LPS
- viscerale vetmassa
- erytrocytenmembraan vetzuursamenstelling |
