Protein blamed for deadlier stroke in diabetics

The reason why intracerebral hemorrhage, a common cause of stroke, has worse consequences in diabetics than in non-diabetic patients, appears to be because high blood sugar increases the ability of a protein called plasma kallikrein to stop blood from clotting near injured vessels, say U.S. scientists who hope the discovery will lead to new treatments that control such bleeding.

You can read about the study, led by the Joslin Diabetes Center, Boston in a paper published online on Jan. 23 in the journal Nature Medicine.

Strokes are a leading cause of death and disability in adults; according to the American Heart Association, they killed more than 137,000 people in 2006.
