Choose your weapon.
I know there is something that shows up in bloodwork that will indicate whether you've ever had a heart attack or not. Had some bloodwork done about five years ago and my doctor said, "Well, you've never had a heart attack." He could tell by looking at the results of the blood tests.
It's troponin, but they generally drop back to normal after 72 hours. I don't think there is any marker in blood to indicate if you've ever had a heart attack. BNP indicates heart failure, but only elevates during an acute event.
In any case, I wouldn't rely on the internet for medical advice.
Actually, I didn't read that on the Internet. My doctor told me that, in person. Quite frankly, it scares the hell out of me to think my doctor doesn't know what he's talking about. I don't know why he would have said that if it's not true. Oh, well, he's a gynecologist, not a cardiologist, but still...
I was referring more to soliciting medical advice from the forum. There are some people on here that have some rather strange beliefs about medicine.
At any rate, your gyn might have known something I didn't or maybe you missheard him.
