Cod liver oil aids blood flowLong-term patency of regenerated neoaortic wall following the implant of a fully biodegradable polyurethane prosthesis: experimental lipid diet model in pigs.
We investigated how a diet rich in cod liver oil affects blood clot formation by studying young pigs implanted with biodegradable polyurethane vascular prostheses. In this research, we used three groups of pigs: a control group, one group receiving a daily dose of aspirin, and another following a lipid-rich diet featuring cod liver oil. Over the course of the study, we noted the patency of vascular grafts at various intervals, particularly focusing on the impact of the lipid diet.
The results indicated promising findings for the pigs on the lipid diet. While the control group showed a 100% thrombosis rate, a remarkable 100% of the pigs receiving cod liver oil had patent grafts. Even at the final retrieval period, most of the pigs on the lipid-rich diet maintained a functioning graft, suggesting that cod liver oil may play a beneficial role in preventing blood clots. This effect could be linked to the diet’s ability to promote better endothelial growth within the graft.
Overall, the study points out that incorporating a lipid-rich diet, particularly with polyunsaturated fatty acids like those found in cod liver oil, may help enhance long-term success for vascular implants. It appears that this dietary strategy could improve outcomes by preventing blood clots and supporting the formation of new tissues in the vascular system.

Cod liver oil prevents clottingPrevention of platelet aggregation by dietary polyunsaturated fatty acids in the biodegradable polyurethane vascular prosthesis: an experimental model in pigs.
In a fascinating experiment involving young pigs, we observed how cod liver oil can prevent blood clotting in biodegradable vascular prostheses. The study included a total of 25 pigs, with 15 of them fed cod liver oil alongside their regular diets. They were compared against 10 control pigs that weren’t given any additional fatty acids.
Over the course of several months, we performed imaging tests and found that all the control implants were completely thrombosed by day 30. In stark contrast, the pigs who received the cod liver oil showed 100% patency—or openness—of their grafts even at later stages of the study.
Upon retrieval, 7 out of 9 grafts in the cod liver oil group remained patent, indicating that the fish oil's rich content of n-3 polyunsaturated fatty acids could significantly modify lipid metabolism. This modification appears to prevent the clumping of platelets, which is a crucial factor in blood clot formation.
Tissue analysis revealed that the patent grafts were well-integrated with tissue resembling natural blood vessel lining, complete with muscle cells that indicate healthy growth. This study clearly shows that a diet enriched with essential fatty acids can play a substantial role in preventing thrombosis in biodegradable vascular prostheses. The combination of our innovative materials and dietary strategies could pave the way for better heart surgery outcomes in the future.

Cod liver oil and thrombo-protectionFish oil, atherogenesis, and thrombogenesis.
We explored the effects of cod liver oil on blood clotting within the context of a broader dietary analysis. The study found that marine fish consumption decreases the likelihood of dying from ischemic heart disease. However, the use of fish oil as a supplement isn't universally recommended due to some potential issues. In high doses, fish oil can lower cholesterol and triglycerides but might also increase low-density lipoprotein (LDL) levels and raise the risks of free radical formation and bleeding.
Our observations with swine indicated that when an atherogenic diet was supplemented with cod liver oil, there was a noticeable decrease in monocyte adhesion and platelet clumps on damaged coronary arteries, even when cholesterol levels were similar to the untreated group. This suggests that fish oil could have a thrombo-protective effect. We also conducted an in vitro assay to understand how fish oil seems to lessen these blood cell interactions.
In our tests, we found that eicosapentaenoic acid (EPA) was particularly effective in reducing the adhesion of human monocyte-like cells to endothelial cells stimulated by lipopolysaccharide (LPS). The improvements were noticeable only when EPA was administered soon after LPS stimulation. Furthermore, EPA exposure also lowered the expression of adhesion molecules on human umbilical vein endothelial cells. These findings imply that EPA could play a role in limiting the inflammation-related mechanisms associated with blood clotting.

Cod liver oil impacts clot formationDietary fish oil reduces microthrombi over atherosclerotic lesions in hyperlipidemic swine even in the absence of plasma cholesterol reduction.
We explored the impact of adding fish oil, particularly cod liver oil, to a high-cholesterol diet on the formation of blood clots in swine. Our study involved swine fed a butter-cholesterol hyperlipidemic diet. We compared groups that received cod liver oil and menhaden oil with those that did not, keeping plasma cholesterol levels similar across all groups. This allowed us to focus specifically on how the fish oil might influence blood clot conditions.
One significant finding was the marked reduction in the number of platelet clumps, or microthrombi, in the swine that received fish oil. The treatment group showed a drop from nearly 1,000 platelet clumps per square millimeter to around 300 to 364, indicating that cod liver oil does indeed affect blood clot formation.
However, the most surprising result from our observation was that even with lower numbers of attached platelets and monocytes, the growth of atherosclerotic lesions—plaque buildup in arteries—was not significantly slowed in the fish oil groups. This contrasts with past studies where reducing plasma cholesterol resulted in a notable decrease in lesion growth.
Consequently, our research suggests that while cod liver oil may reduce certain aspects of blood clot formation, it does not significantly impact lesion development under the conditions we studied. This might imply that other factors, particularly plasma cholesterol levels, are critical in controlling lesion growth over the longer term.

Cod liver oil aids blood clottingNormalization by dietary cod-liver oil of reduced thrombogenesis in essential fatty acid deficient rats.
We conducted research on the impact of cod liver oil (CLO) on blood clot formation in rats that were deficient in essential fatty acids (EFA). The study included diets with different types of oils, including sunflower seed oil (SO), which is rich in linoleic acid, and hydrogenated coconut oil (HCO), which does not contain EFAs.
Our findings revealed that both CLO and SO helped reverse the reduced ability of these EFA-deficient rats to form blood clots. Notably, the SO diet restored arachidonic acid levels in platelet phospholipids, which is essential for normal blood clotting. In contrast, while CLO did not influence arachidonic acid content, it significantly increased levels of other beneficial fatty acids—timnodonic acid (EPA) and cervonic acid (DHA).
Despite these positive changes, further research is necessary to determine if the alterations in fatty acid composition, particularly from CLO, are directly linked to the normalization of blood clot formation in these rats. We are particularly curious about the possible role of eicosanoids, compounds derived from fatty acids that might be influencing this process.
