You'll be in my prayers here.
When they were talking about your enzymes being good, I'm sure they ran labs to test for enzymes that show up after a myocardial infaraction (heart attack). That's pretty standard procedure when someone is admitted for severe chest pain.
My brother actually had a heart attack at 40 and didn't even know it until he went to the doctor for something else several months later. They also did a heart cath on him. He's now on some heart medications, and will be for the rest of his life.
Unfortunately he's a workaholic and runs himself to the bone, so he hasn't made any healthy lifestyle changes for himself. He's stressed to the max, and chooses to live that way. There's nothing I can do about that except keep him in my prayers.
