An angiogram gives the clearest picture of your heart s arteries. Doctors don t recommend them lightly. Consider yourself lucky. My doctors waited too long for an angiogram, and I need a triple bypass the next DAY. I had been having odd problems for 4 years. Two of three widow-maker arteries were 99% blocked. They were afraid I would not make it to the next afternoon. Complications are about 1 in 1200. Fatal heart attacks occur about 50% of the time. Which odds do you like better, 50/50 for life or death risking a heart attack, or 1199/1200 for life with a successful angiogram ?
