I had an Angiogram a few months after I broke my ankle a couple of years ago. I remember the warm feeling when they injected the dye, it was a strange feeling. They found a minor blockage but not enough to require a stent. I was on meds for a while but gradually got off them. Bruising was a *****, I couldn't hit anything with bruising. Since I've been off the meds no issue with bruising. It did bother me slightly when I rode but figured it was just another risk of being on the bikes. Changed my diet and that has helped as well.
Good Luck
