Is It a Hard Attack, or a Stroke?

There's one study i talk about in the book, particularly where t they took like a, it was about 60 % of the total admissions for hard attacks from about two thousand six, two thousand 11 in states. I don't remember the exact statistics, but a very large number of them, like half or more, had normal or optimal clustra at the time of their admission to the hospital with a hard attack. So, m it doesn't really suggest that that number is, i guess, superimportant. Ouo, could be anything. Coun be normal, abnormal, and its kind of errelevant to whether or not someone's going to have a hard attack.
