title: My doctors were concerned that I had abnormal troponin levels and cardiac symptoms. Prior to a coronary angiogram, I was given an intravenous dose of heparin, and now take a beta-blocker, metoprolol, 12.5 milligrams twice a day. I bleed a lot and bruise when I have a cut or a contusion. Why?
