I just found out. Mom says she didn't want to call and have me up worried all night with nothing I could really do from here. I'm like - AAGH. Doesn't matter if I can *do* anything; I need to *know*.
They're pretty sure it wasn't a heart attack. He had a CT scan last night and will have a stress test and ultrasound today, looking for an aneurysm; they want to catheterize him, but he doesn't like this hospital, so he's standing firm on "nothing but non-invasive tests". Dad's a representative for a company that makes cardiovascular surgery stuff (he specializes in stent grafts), so there are local hospitals where he's very familiar with the staff, and if he's having surgery, he's having it at one of those; this just happened to be the hospital across the street from the restaurant.
*deep sigh* I want to be there now.
EDIT: He has confidence that he'll be fine - but it should be said that he *always* has confidence. I often say I was raised by wolves, but when I was not under the influence of said wolves, I was modeling myself on Dad - that aggressive confidence I have that the world will not fall apart because that is just not an option, that I can do impossible things out of necessity? Yep, that's from Dad. So he has confidence, but he's also 65, and while his health in general is not terrible... he's 65 and he just passed out in a restaurant. So yeah. We'll see.
