Bill, Sorry to hear about your heart health issues. I would recommend your see a Naturopathic Doctor. They actually study nutrition and how it affects the body (you are what you eat is a true statement). They would be able to answer your question regarding diet & exercise and if it could reverse plaques. Sounds like your are already seeking alternate therapies. If you haven't seen a naturopath yet, that would be my recommendation. As my wife tells me, "Don't self medicate, ask a professional". The level of expertise on some Naturopathic doctors is amazing.
Take a look at Dr. Mercola's website as well.
