심혈관계질환의 위험지표로서Omega-3 Index에 대한 올바른 이해 및 한국인에의 적용

초록

Of all known dietary factors, long-chain omega-3 fatty acids (eicosapentaenoic acid and docosahexaenoic acid) may be the most protective against death from cardiovascular disease. Evidence continues to accrue for benefits of omega-3 fatty acids in the prevention of coronary heart disease and stroke. Anti-arrhythmogenic, anti-inflammatory, anti-thrombotic and hypolipidemic effects of omega-3-fatty acids are emerging as the most likely explanation. New evidence has confirmed and refined the cardioprotective risk factor of Omega-3 Index, the only standardized blood test of omega-3 fatty acids measuring content of erythrocyte eicosapentaenoic and docosahexaenoic acids. Current evidence suggests that individuals with coronary artery disease may reduce their risk of sudden cardiac death by increasing their intake of long-chain omega-3 fatty acids by approximately 1 g per day and achieving a target range of 8-10% Omega-3 Index. However, target range of Omega-3 Index for Koreans may be higher than 10%.
