Relation of Whole Blood n-3 Fatty Acid Levels to Exercise Parameters in Patients With Stable Coronary Artery Disease (from the Heart and Soul Study)

Dietary intake of n-3 polyunsaturated fatty acids is associated with a lower incidence of cardiovascular events. Mechanisms underlying this association are poorly understood but may include beneficial effects on physical conditioning and vagal tone. We investigated the association of n-3 fatty acid levels to exercise parameters in 992 subjects with stable coronary artery disease. Cross-sectional associations of heart rate recovery time,...
