I'm on my 11th year of playing hockey post-stent placement. I had what the cardiology world refers to as the Widow Maker back in December of 2008. I wasn't on a traditional blood thinner like Cumidin but I did take Plavix for a while. I had to be careful not to get cut just the same and bruising was pretty bad if I took a puck to a soft area.
Here is what will happen. For at least the first few months you will strictly adhere to your dietary recommendations. If you were a drinker then you'll most like cut yourself back to no more than 2 adult beverages on a given day. I began mixing the non-alcoholic beers into my routine and still do even though I have become a little more lax in that regard. You will become acutely aware of every new sensation in your body and experience many anxious moments when something feels "strange". Relax, most of them are just normal aches and pains that you never thought twice about before your diagnosis. That said, be mindful of the warning signs and don't be embarrassed when you overreact with a trip to the ER only to stay overnight and be told you're fine. It will happen and better safe than sorry. I was about 11 months past getting my stent when I felt weird and disconnected one morning. Spent a night in the hospital followed by a stress test the next morning to find that it was nothing.
You may also become obsessive with taking your blood pressure at home. I would do it every morning and if I didn't quite like the reading then I would do it again. Sometimes up to 4-5 times in a row. This is counter productive for 2 reasons. First, you'll make yourself anxious which will increase the readings and second because taking so many within a relatively short amount of time may also do the same. I've relaxed about taking the readings so often but now I can feel what a tester is listening for and if I can see the dial or monitor screen am able to tell what the reading will be before they do.
One thing that I always keep in mind and keeps me from panicking is this; if you can recreate a pain or ache with touch or movement then it is most likely exoskeletal or muscular.
You will get back on the ice. For me, it was 3 months after my cardiac event and going thru 12 weeks of cardiac rehab (basically 3 weekly sessions of increasing effort exercise under the watchful eye of trained specialists). There was no better feeling than getting back out there. You will check your heart rate on the bench and will be more aware of your breathing recovery. It is all part of the process.
