I tried to resolve my blockages with drugs, exercise, and diet, but continued to have
angina and finally heart attacks, rejecting stents or bypass. For whatever reason, I don't grow good collateral arteries that some people develop to feed oxygen to the heart in areas where blockages are present. Stents greatly improved my heart function, combined with drugs, exercise, and diet. I have four drug-elluting stents and four bare-metal stents.
