Omega-3 Index: an emerging biomarker in cardiovascular prevention.
Narrative review of the Omega-3 Index (erythrocyte EPA+DHA) as a cardiovascular biomarker: argues long-chain omega-3s are cardioprotective (index <4% linked to high risk of cardiac events/sudden death, >8% to protection) and predict all-cause mortality better than dietary questionnaires, attributing trial controversy to reliance on estimated intake. Nutrient/biomarker-level evidence, not salmon-specific.
