Well just from my experience in being in Cardiac ICU and how I felt...I didn't even really like when my family came to visit...It sounds bad but I was in bad shape and didn't have the energy to "visit"
Now with that being said once I was transfered to IMC (intermediate care) I loved having visitors, I felt better and was doing better and needed to chat and talk.
Helping that dad out with errands and things is a great help...I loved that my friends helped take care of my hubby and kids when I couldn't it made it less stressful being usless in bed.
