I did almost the same thing 13 years ago. I hope and pray things go well for you.
As the ER doctor said, major/major heart attack, got me stable enough to ship out to another hospital..... to critical for them so I laid around there a couple of days until stable enough to ship out to another hospital....laid around there until stable enough for surgery.....still had my dirty clothes on when they took me down for surgery....hadn't eaten or slept much for 5 days....still hurting like hell......I had so many blockages they didn't know what to do....I told them "angioplasty" save those leg arteries for when I really need them.... had angioplasty and came out of surgery hungary as hell....ate a big meal and felt great.....The doctors have been amazed at me. Very little heart damage, still ticking and kicking even though they've been after me for 10 years to have a pacemaker put in.
Hope you're not as dumb as me........ but at least as lucky.
