Primary Prevention
• Antioxidants −Source includes dietary such as beta-carotene, Carotenoids(Vitamin A), ascorbic acid
(Vitamin C), Vitamin E (alpha and gamma tocopherol).− The most common vitamin E supplement (dose 400IU) daily is 10 times the target daily dietary
consumption. • Primary Prevention of CV disease
−Supplementation with vitamin E, vitamin C, and beta-carotene have not shown benefit for primary prevention of cardiovascular disease.
−The US Preventative Services Task Force (USPSTF) found insufficient evidence to recommend for or against supplements for vitamin A,C,E or combinations for primary prevention and recommended against the use of beta-carotene for this purpose

Nutritional Supplements and Lipid Lowering
Guggulipid(Guggul, an extract from Mukal Murryh tree) This has been used for hypercholesterolemia. Conflicting evidence on LDL from limited trails.
Policosanol
(Extracted from sugar cane wax and contains aliphatic alcohols) Some studies suggest at 10‐20mg/day could reduce LDL 25% or more and raise HDL up 15%. (conflicting evidence from limited studies with no placebo to compare). Studies outside of Cuba failed to demonstrate any effect.
Coconut Oil Claims that coconut oil raises HDL. (Conflicting evidence from limited studies, potential increase in LDL).

Nutritional Supplements and Lipid Lowering
GarlicAdvocated as method to lowering cholesterol concentrations.
*No significant effect on LDL or other lipid levels.
Polyphenols
(flavonoids and derivatives, ligans, phenolic acids, stilbenes) are found in plants and food from plants that appear to have antioxidant effects, immunomodulatory, and vasodilator properties.
*Limited evidence on lipid lowering effects.
Tea Limited evidence finding reduction of LDL with no effect on HDL.

Nutritional Supplements and Lipid Lowering
Red yeast rice
May have cholesterol lowering ability; however, there is lack of standardization in products. Marked variability in the amount of active ingredients (same as Lovastatin) may result in unpredictable reduction in LDL.
Flaxseed
Interventions reduced total and LDL cholesterol. Significant reductions were observed with whole flaxseed. Effects were more apparent in females (particularly postmenopausal women) and individuals with high initial cholesterol concentrations. No significant changes were found in the concentrations of HDL cholesterol and triglycerides.
FiberCertain soluble fiber (psyllium, pectin, wheat dextrin, and oat products) are effective at reducing TC and LDL. Fiber added as supplement or as part of dietary modification can reduce cholesterol levels.

OMEGA-3 Fatty Acids • Long chained n-3 polyunsaturated fatty acids in fish oil, eicosapentaenoic (EPA) and docosahexaenoic acid
(DHA) are important for healthy cardiovascular system. • DHA is also important for early brain development during gestation and infancy. • Fish oil may also affect cognitive decline and dementia, depression, other neuropsychiatric disorders, asthma,
and other inflammatory disorders.
Dose (N‐3 PUFA) EffectTypical dietary intake (<300‐500mg/day) May reduce cardiovascular events.
Low dose (~1g/day) GISSI trial showed reduction in cardiovascular mortality, mostly due to reduction in sudden death. Results not confirmed in subsequent trials.
High dose (4g/day) Additional physiologic effects such as TG lowering and may lead to reduction in total CV events. (REDUCE IT TRIAL)

Benefits of Fish Consumption
Reduces risk for acute coronary syndrome (ACS)‐ Those who ate the most fish (four or more servings per week) had the lowest rate of ACS compared to those who ate the least.
Lower danger of heart failure‐ Compared to those who rarely or never ate fish, those with higher intake were less likely to suffer heart failure.
Protection against stroke‐ even infrequent fish intake (one to three servings monthly) helped protect against ischemic stroke, compared to people who never ate fish or consumed it less than once a month.

Effects on CV risk factors:
•Fish oil lowers TG 25-30% ( similar to other TG lowering drugs).− Little TG lowering with low dose, higher doses appreciably lower TG levels. −Metanalysis of 55 trails, show each 1g/day increase in EPA + DHA reduced TG by 5.9mg/dL.

The median duration of follow-up was 5.0 years.The primary end point, a composite of death from cardiovascular causes or hospital admission for cardiovascular causes, occurred in 1478 patients (11.8%), including 733 of 6239 patients who received n-3 fatty acids (11.7%) and 745 of 6266 who received placebo (11.9%).

Recommendations:
Adults without known CHD seeking healthy diet should consume 1‐2 servings/week of fish. If not consumed in diet, supplement with daily fish oil (1g/day).
Patients with known CHD, at risk for CHD, or heart failure consumes 2 servings/week of fish. If unable to obtain from diet, consider daily fish oil (1g/day).

Dietary Fish Consumption and Omega-3 Supplements
Low dose N‐3 PUFA effects on cardiac mortality and total CVD in primary
prevention depending on fish background remain unclear.
Recommend eating fish ( oily or dark
meat) twice per week.
Possible benefit, lack of harm‐ low dose
supplement ( 1g/day) reasonable.
Patients with high TG, use higher dose
(4g/day) reasonable as adjunct to statin therapy to reduce
CVD disease.
