Effect of Fish Oil (Omega-3 Fatty Acids) on Arteries

Stopped early · Phase 3 · Has a placebo group

Conditions studied: Metabolic Diseases, Endocrine System Diseases, Heart Disease, Vascular Diseases, Diabetes, Cardiovascular Disease, Glucose Metabolism Disorders, Hypertension

In brief

The overall objective of LUCHAR Specific Aims 4.1 and 4.2 is to assess the additional contribution of cardiovascular disease (CVD) risk markers to traditional biomedical risk factors in the prediction of pre-clinical CVD. Specific Aim 4.3 will test the impact of omega-3 fatty acid supplementation on risk markers and pre-clinical markers of CVD in Hispanic patients. Specific Aim 4.3: Conduct a randomized, placebo-controlled trial of the effect of omega-3 fatty acid supplementation on vascular function as measured by brachial artery reactivity (BAR) and on circulating inflammatory markers. Hypotheses: 1. Daily omega-3 fatty acid supplementation will improve vascular function in subjects at high risk for CVD. 2. Daily omega-3 fatty acid supplementation will reduce inflammatory protein panel scores in subjects at high risk for CVD.
