Stroke Patients Benefit From Dissolving A Blood Clot In The Brain Up To 4.5 Hours After A Stroke

Patients can still benefit up to 4.5 hours after a stroke if a drug that dissolves blood clots in the brain is administered. Thus far, three hours had been considered the useful limit for administering thrombolytic drugs. The results of the "European Cooperative Acute Stroke Study 3" (ECASS 3) have now been published in the New England Journal of Medicine.
