The feeding of large amounts of fish or fish oils to healthy volunteers has
been shown to reduce plasma triglycerides and platelet aggregation, and
prolong the skin bleeding time. To determine whether a commercially
available marine oil (MaxEpa) would have similar effect in stroke patients,
we performed a double-blind, placebo-controlled study in 11 patients (7
men, 4 women) with completed stroke (7) or transient ischemic attacks
(TIA's) (4). Ten 1 ml opaque capsules containing either MaxEpa or olive oil
were given daily for 6 weeks, and then the patients were crossed-over.
Aspirin was avoided during the trial. The data were analyzed by
paired-sample t-tests. A significant reduction was found in serum
triglycerides, but total serum cholesterol and HDL cholesterol were
unaffected. The bleeding time was modestly prolonged after 3 weeks of
treatment, but the differences between MaxEpa and olive oil treatments were
not significant at 6 weeks. Aside from an increase in collagen-stimulated
malondialdehyde formation no other statistically significant changes in
hemostatic factors were observed. We conclude that the ingestion of up to
10 MaxEpa capsules daily for 6 weeks has little influence on such
established risk factors as cholesterol concentration and platelet function
in patients with stroke or TIA's.
