I had to have a chemically induced stress test because of being over 50. To my surprise I flunked. Had to have a heart cath, there was a blockage and instead of doing a stent which would have held me up an additional six months, my cardiologist did a ballon which only delayed me one month. He wanted me to have the surgery ASAP. 29 more days. Don't be too scared. They will check it out and you will be the better for it.
It's so funny, I got on here to ask the same exact question. Thanks for beating me to it. I'm going to work feeling better. It's hard not to think your going to be the one person it doesn't work for. Guess that is what this site is for. Support from people that have been there. Thanks!
