Ridker's latest study is based
on an eight-year follow-up of
                            27,939 volunteers in the Women's
Health Study. About half of
                            heart attacks and strokes
occurred in those with seemingly safe
                            levels of LDL, the bad
cholesterol.

...and so about half occured in those with "high" levels of
cholesterol too?
