We explored how omega-3 fatty acids, particularly eicosapentaenoic acid (EPA), influence blood clot markers in patients with atrial fibrillation (AF). Our research involved a large group of 2,373 patients, assessing the levels of D-dimer and beta-thromboglobulin (BTG), which are indicators of blood clotting activity and platelet activation.
The results showed that higher total omega-3 fatty acid levels were linked to lower D-dimer and BTG levels, which suggests a potential antithrombotic effect. Notably, the individual omega-3s, including EPA, docosahexaenoic acid (DHA), and others, generally displayed similar associations.
While EPA had a small positive relationship with BTG, DHA, DPA, and ALA were associated with lower BTG levels, indicating varied effects among these fatty acids. Overall, we found that increased omega-3 fatty acid levels could contribute to reduced activation of blood clotting mechanisms in patients with AF, highlighting the potential benefits of omega-3 intake for cardiovascular health.
