Like heart attacks, some strokes are caused by interruption of blood predominately from a blood clot, only this time in the brain. As in heart attacks, there is a window of time (optimally within 90 minutes but generally no more than three hours) in which clotbusting treatment can result in patients suffering little to no long term damage and disability from these events. Therefore, patients transported to specialty centers for the clot-busting treatment of strokes can benefit from a well-coordinated ground and air system to accomplish early transfer.
