Fish Oil, Metformin and Heart Health in PCOS

OBJECTIVES The objective in this proposed study is to determine the effect of dietary fish oil supplementation with metformin compared to standard of care metformin-alone treatment for 12 months on plasma lipids and apoB- remnant lipoprotein metabolism, and atherosclerotic cardiovascular disease and cardiac function in high-risk overweight-obese young individuals with PCOS. This study will provide evidence-based research on the efficacy of fish oil, in the form as an adjunct therapy to standard treatment with metformin, as a safe nutritional treatment to add to therapeutic guidelines to reduce early CVD risk in young women with PCOS. Specific Objectives; 1. To quantify carotid intimal medical thickness (cIMT) and plaque height before and after the intervention to assess the effect of fish oil supplementation combined with metformin standard of care on atherosclerotic cardiovascular disease and cardiac function. 2. To determine the effects of dietary fish oil supplementation combined with metformin and metformin standard of care on fasting and non-fasting plasma TG, apoB48 and apoB100-lipoprotein concentrations, and cardiac function variables including left ventricular (LV) posterior wall thickness, LV ejection fraction. 3. To assess the effect of dietary fish oil supplementation on insulin, glucose, and endocrine parameters.
