Every 15-minute delay in delivering a clot-busting drug after stroke robs survivors of about a month of disability-free life, according to a new study in the American Heart Association journal Stroke.
On the other hand, speeding treatment by just one minute means another 1.8 days of healthy life, researchers said.
Save a minute; save a day is the message from our study, which examined how even small reductions in treatment delays might benefit patients measurably in the long run, said Atte Meretoja, M.D., Ph.D., M.Sc., lead author of the study and associate professor of neurology at the University of Melbourne in Australia.
The clot-busting drug tissue plasminogen activator (tPA) to treat ischemic stroke, should be given within 4.5 hours of symptom onset. However, the sooner its given, the better the outcome.
Clot-busting treatment works equally well, irrespective of race, ethnicity or gender, Meretoja said. Speedy restoration of blood flow to the brain is crucial for brain cell survival everywhere.
The worlds fastest stroke services in Helsinki, Finland and Melbourne, Australia, take an average 20 minutes from hospital arrival to start of treatment, he said. Most American, Australian and European centers take 70-80 minutes.
In this study, we wanted to quantify the importance of speed in the hope that concrete easy-to-relate-to figures will inspire medical services to measure and improve their game for the benefit of our stroke patients, Meretoja said.
Meretoja and colleagues used evidence from the combined major clot-busting trials reported to date. They applied those findings to 2,258 consecutive stroke patients from Australia and Finland to calculate what the patient outcomes would have been if they had been treated faster or slower.
They found:
