That may well have been what caused this whole thing.

In other words, 81 milligrams a day gives as much benefit as higher doses with potentially less risk of bleeding.

Our study found that aspirin treatment was associated with a 24 percent reduction in the risk of the most common type of stroke in women and a 32 percent reduction in heart attacks in men.

In both men and women, there was an approximately 70 percent increase in the risk of bleeding associated with the taking of aspirin. And it is known that the bleeding risk associated with aspirin is dose-related.

In women, aspirin prevents strokes and doesn't have any real effect on heart attack, and in men aspirin prevents heart attacks but has no effect on the prevention of strokes. So there appears to be a gender-based difference in the beneficial effect of aspirin.

Aspirin prevents the blood in the body from clotting, and because stroke and heart attack are both caused by the formation of blood clots in the body, anything that prevents blood clotting from forming would be expected to have a beneficial effect in those diseases.

Aspirin affects platelets differently in men and women.

His prognosis for any kind of meaningful recovery is absolutely nil.

He's not going to survive this. If you're his family, you hope he survives the night.
