Well, I reversed mine with a low fat diet and exercise over about a 3 year period. There is a book written by Dr. Dean Ornish called Reversal Of Heart Disease
... I believe that is the name of the book .. If not that is very close.. It tells how to do it... and it is where i got my information. I am 66 years old and just recently had a stress test
and maxed out the test.. Stayed on the tread mill for 15 minutes with it at its highest incline and highest speed.. The cardiologist couldn't believe it.
I eat a low fat diet and walk 6-8 miles daily.... It works if your willing to do it.. most people are unwilling to do what I did... it seems... you cant correct it overnight but it can be done .. I would highly recommend you purchasing Dr. Ornishs book... best of luck.
Also Dr. Ornish is one of the very best experts on Cardiovascular health and diseases... he is great... and has several books at most book stores...
