Brief Summary

Epidemiological and clinical evidence suggests that high-dose intake of long-chain n-3 fatty acids have a favorable role in altering blood TG and non-HDL cholesterol when combined with statins in hyperlipidemic patients. Their efficacy in altering low density lipoprotein cholesterol particle size and concentration is yet to be confirmed. This study evaluates the effects of adding 4/day eicosapentaenoic acid (EPA) + docosahexaenoic acid (DHA) to stable statin therapy on blood TG, non-HDL, LDL-C as well as small dense (sdLDL) particle concentration in a group of hyperlipidemic patients. In this randomized, placebo-controlled, double-blind parallel group study, 44 subjects who were already on statin therapy for \> 8 weeks and had non-HDL-C levels above the National Lipid Association Recommendations were randomized into two groups. For 8 weeks, together with their prescribed atorvastatin, the intervention group received 4g/day EPA+DHA (in ethyl ester form) while the control group received 4g/day olive oil (placebo). Baseline measurements of non-HDL-C, TG, TC, HDL-C, LDL-C, VLDL-C and sdLDL were repeated at week 8. Differences in dietary intake were assessed with a weighed 3-day food diary at week 4. Primary outcome measures are the percent change in non-HDL-C and sdLDL particle concentration from baseline to the end.

Eligibility Criteria

Age50 Years - 70 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male and female, aged between 50 and 80
  • Current combined hyperlipidemia: people whose LDL and non-HDL levels are above the National Lipid Association recommendations according to their risk groups. non-HDL is also considered given the fact most recent research states looking at both values is a better risk indicator than looking at LDL alone. (Appendix 12: National Lipid Association Treatment Guideline)
  • Currently on statin prescription.

You may not qualify if:

  • Current use of n-3 supplements
  • Recent history of certain heart, kidney, liver, or cancer:
  • Patients that have had any type of heart surgery, Patients that are diagnosed with any type of cancer and/or have had any kind of cancer therapy, Patients that have had kidney failure, Patients that have had liver failure, in the past 6 months
  • Pregnant or lactating females
