Visit to the Dr's went well. He told my wife and I that it was pretty much a genetic heart attack. All of my other arteries are 100% clear it was "just" the posterior descending cardiac artery that was 100% blocked. He told me to take it nice and easy for the next week and then "ease back into life." Even said he feels I will be off all medications within 3 months.
SO, I may just try and tackle the transom myself after all. Giving serious thought to pouring it. Spent some time reading about the process and am sure I can handle it.
