His question that I have not been able to get satisfactorily answered

anywhere is whether the use of substantial amounts of flax oil or seed (or other possibly good sources of om 3s) is a good idea when a person has existing coronary artery disease as evidenced by chest pain on exertion?

Or are large amounts (e.g. 1 tbs or more) of flax oil, etc. only advisable as a preventive against cardio-vascular disease? Dr. dean ornish advises against vegetable oils, even of the highest quality, except in extremely small amounts for heart patients. Ornish himself has stated that he uses about 1/2 tsp! a day.
