Cleveland OH, (CNN) — A third of all stroke victims don't call an ambulance to get them to the hospital, leaving them vulnerable to delayed treatment and worse outcomes. That's according to a new study published in the journal "Circulation."
The authors analyzed data on more than 200-thousand patients, seen at more than 15-hundred hospitals in the United States, over seven years.
Patients who arrived by ambulance were about twice as likely to arrive at a hospital quickly and they were about 50 percent more likely to receive a clot-busting drug within the recommended three-hour window, when it's most effective. The study also found younger stroke patients and ethnic minorities are less likely than others to call an ambulance.
