Have to agree that it's a good thing you had to get that angiogram done.
Alas, when I had my stents put in, the nurse doing the prep for going in through the femoral artery was not particularly cute at all.
And that damned room was insanely cold!! They took care of me with some nice warm blankets. Like you, I could feel it when they got to the blockage with the stents and let them know. "Yep, that's us. You're doing fine."
The sedation was great. I vaguely remember being moved up to the ICU. And like you, I was sandbagged down in the groin to hold pressure on where they went in. Which I expected and was fine with...until I had to pee. I negotiated with the nurse for the old pee cup, but it just wasn't happening for me. "Either I get up and go to the bathroom, or I'm going to pee the bed!" I got my way and despite a wobbly start, made it to the bathroom - wired up like a Christmas tree, mind you - for one of the most glorious pees I have ever taken.
Other than the effects from the sedation, I felt perfectly fine afterwards - no pain or lingering effects. Maybe you were just reacting to the meds?
All told, I was in the hospital for 2.5 days. So you're on a similar track. The good news is, once you get past the crap from where they went in, it's back to a relatively normal life. Guessing that you're going to be on blood thinners for a bit, probably a beta-blocker like Metoprolol and maybe a statin as well. Standard fare for post-cardiac care. Doc may want you to cut out the caffeine and salt as much as you can. My cardiologist was pretty easy on those - he focused on me quitting smoking. Which is how I ended up here.
You're well ahead in the game. You didn't want to find out about those blockages by having a full-blown heart attack, trust me. And you're still on the green side of the grass.
It's where we like you best!!
Best wishes for getting back in the saddle of livin' ASAP!
