Cardiovascular disease (CVD) overview


Cardiovascular disease (CVD) is an umbrella term that encompasses all diseases of the heart and blood vessels. There is a general consensus that adequate intakes of fish, fish oil, or omega-3 PUFA supplements have favorable effects on cardiovascular outcomes. However, the primary cardioprotective effect of long-chain omega-3 PUFA seems to be on the last step of CHD, arrhythmia. For this reason, sudden cardiac death (SCD) appears to be the most consistently affected clinical outcome (77, 81).
