Best wishes for a full and speedy recovery.

Don't know whether it helps but I've got two friends who had heart attacks last year, both of whom are back to full fitness. One, like you, had a stent fitted and recovered very quickly. The other had a quadruple by-pass and, although his recovery was slower due to the surgery, is now fine and leading a normal life.

In a way it is fortunate to have a warning - some people aren't so lucky.
