The most important thing is to seriously consider what you're eating. Please know that I want to help and not offend, but certain foods as I'm sure you know, block the arteries. There is a way to reverse that by giving up everything that contains fat. So all dairy, meat, fish, poultry and oils. I can recommend some great books that will really help if you're interested. I switched to this diet a few years back and recently had a full blood test. The doctor said he wished the results were for him. They were all excellent. So why not give it a try? As for exercise, don't do anything too strenuous for now, just walking and perhaps yoga, all good exercise. I wish you luck and hope you let me know about the books.
