I have had my share of arterial grafts and stents over the past 13 years. I was on Plavix for 12 years and then this winter had a triple open heart coronary artery bypass. They had me on Coumadin after that but switched me to Xarelto after I got out of the hospital. All three of these will cause bruising on my lower arms and backs of my hands but that is the only place I have had it. All my doctors know of my gun hobby and none have ever said anything about not continuing to shoot. My surgeon said he may accept my invitation to shoot at my range this summer. The nurses all new of my gun interest and rather than being turned off they were full of questions. Some were anxious to tell me they had gotten their concealed carry. Stay in close contact with your heart doctor and ask him what he thinks. I have never been asked about gun ownership like you read in some of the emails circulating the web.
