They taught me to cross my arms when coughing, and there's this specific move he needs to do when getting out of bed—it sounds silly, but he really should lean on his right side when getting up (the hospital staff probably needs to walk him through that). Right now, wires are holding his ribcage together; the bones will heal eventually, but until then, he’s gotta be super careful. Cross those arms when coughing, don't jerk his neck around, just turn his whole body slowly. Also, if he's in a car, he shouldn't make any sudden turns, otherwise it'll feel like his head weighs 200 pounds—every little movement is gonna hurt. And when he grabs a bottle, like a 1.5-liter soda, he should always use both hands. He also needs to watch his step so he doesn't trip.
As for the heart stuff, I honestly don't know much about it. I was lucky (or unlucky, I guess) that it happened when I was only 35, so aside from some twisted veins and carrying a few extra pounds, I'm okay.
I'm just on low-dose aspirin and Sortis, that's about it.
It's become such a routine now. They'll need to explain everything to him at the hospital while he's still fresh from surgery. Once they take all that gear off—and trust me, it looks like a bunch of random stuff sticking out from his neck to his chest—he'll be fine. Don't worry too much.
Once Dad gets home from the hospital, figure out where you want to go for walks with him. Wishing him all the best! You can shoot me an email if you want, I'd love to hear how everything turned out.
