Omega-3 Fatty Acid and Cardiovascular Disease

Monoswini Banerjee [2]


Abstract: Cardioceuticals are nutritional supplements that contain all the essential nutrients including vitamins, minerals, omega-3-fatty acids and other antioxidants like a-lipoic acid and coenzyme Q10 in the right proportion that provide all round protection to the heart by reducing the most common risks associated with the cardiovascular disease including high low-density lipoprotein cholesterol and triglyceride levels and factors that contribute to coagulation of blood. Omega-3 fatty acids have been shown to significantly reduce the risk for sudden death caused by cardiac arrhythmias and all-cause mortality in patients with known coronary heart disease. Omega-3 fatty acids are also used to treat hyperlipidemia and hypertension. There are no significant drug interactions with omega-3 fatty acids. The American Heart Association recommends consumption of two servings of fish per week for persons with no history of coronary heart disease and at least one serving of fish daily for those with known coronary heart disease. Approximately 1 g/day of eicosapentaenoic acid plus docosahexaenoic acid is recommended for cardio protection. Higher dosages of omega-3 fatty acids are required to reduce elevated triglyceride levels (2-4 g/day). Modest decreases in blood pressure occur with significantly higher dosages of omega-3 fatty acids. Lifestyle intervention such as consistent aerobic exercise and a diet high in fruits and vegetables promotes cardiovascular health. A heart-healthy lifestyle decreases the risk of coronary heart disease and heart attack. Although it may seem intuitive that dietary fat is bad for the heart and that it must be avoided, certain unsaturated fats are heart healthy, and other saturated fats are not good for the heart. These heart-healthy unsaturated fats are known as omega-3 fatty acids. The 3 main omega-3 fatty acids that are beneficial for cardiovascular health are ?-linoleic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). ALA is primarily found in plant-based foods such as olive, soybean, canola, walnut, and flaxseed oils, and in walnuts and flaxseeds, as well. EPA and DHA are primarily found in marine-based foods that include the variety of fatty fish, such as tuna, salmon, mackerel, herring, trout, halibut, and cod. This Cardiology Patient Page will present the beneficial effects of omega-3 fatty acids on cardiovascular health, explain the possible mechanisms for these effects, and offer recommendations that can be implemented into a healthy lifestyle to further promote good cardiovascular health.
