The aim of the study is to examine the effects of fatty fish and white (lean) fish on cardiovascular disease risk factor levels in subjects with established coronary heart disease using multiple medications. The main end points are blood pressure, serum lipids, inflammatory markers, arrhythmias and gene expression in peripheral mononuclear cells. The study design was a controlled, parallel study lasting 8 weeks with three diet groups: fatty fish, white fish and control group (lean pork, beef or chicken).
