I know there's a huge difference, and also were all different, but my brother recently had 5 stents fitted. Thanks to a marvellous health service, this was done before any heart attack could take place. He is like a man possessed, and I can't keep up with him. I actually thought at one point, I can't waIt until I get my re-bore.
The heart rehabilitation nurses were very poor and only any real use to the nearly infirm, but as long as you follow the advice from the surgeon, you shouldn't have too many problems apart from trying to remember to take the myriad of tablets you'll inevitably have now to take. Good luck with the remainder of your rehabilitation.
