Glad to hear you got one scheduled. I had one when I was 40 and found out heart and arteries were all in great shape-all the other tests up until then just weren't conclusive. I bet yours will be the same but if they do find something it is much better to know about it and how to treat it than not know and then have something much worse happen. Let us know how it goes.
Be prepared for some short but pretty intense "heat" when the dye reaches the brain and groin areas. It was interesting to watch them inject the dye on the screen and then feel how quickly it reached those extremeties. There was no mistake it hitting it's mark!!!
