Mark,
Congrats on the good angio.
For me - the only things I wanted in the hospital:
1. Boxers or shorts for after the foley catheter is removed (to get some semblance of your modesty back)
2. My razor
3. My toothbrush.
That was it for me. I didn't have time to read (I spent alot of time online at VR.COM from the day after my surgery), I didn't watch much TV. I didn't have time to want an iPod.
I watched TV the night after surgery in ICU. Next day was transfer to a private room on cardiac floor. Full of visits from nurses, PT, more nurses, PT, family, PT, nurses... Following day was full of visits from family, friends, nurses, PT. Last morning was nurses, family, surgeon's nurse practioner, discharge paperwork, and last minute PT instructions.
Once they had me walking (the day after surgery) - I walked alot and did arm exercises alot, and breathed alot. Believe it or not, between those activities, nurse visits, and family the day was gone.
For me there was never a time to just stop and do nothing (except at night while trying to sleep and listening to all the noise from the nurses station).
Your wife may want magazines or a book for waiting during surgery or other times during the day if you nap (depending if other family will be hanging around and how talkative they are).
Priscila hacked an open wireless network and so was able to work some during her time at the hospital.
Good luck,
David
