High omega-3 fatty acids and low omega-6/omega-3 ratio but not polyphenols in diet decrease inflammatory markers in men with chronic coronary syndrome treated with percutaneous coronary intervention.

Cross-Sectional Study

This study found that people with heart disease who ate more omega-3 fatty acids (like those in fish) had lower levels of two blood markers that show inflammation in the body — which means omega-3s may help calm down harmful body inflammation after heart surgery.
