But in November, physicians were wowed when a key study revealed that prescription-strength doses of eicosapentaenoic acid (EPA), a form of omega-3 fish oil, reduced the risk of cardiovascular death, heart attack, stroke, revascularization and unstable angina by 25 percent in patients with CAD or diabetes and high triglyceride levels.
