Shorter stroke treatment delays tied to more healthy days



Shaving even a minute off the time between the onset of a stroke and initial treatment may add to the amount of "healthy" days people have afterward, suggests a new study.

Researchers found that stroke patients gained about two days of healthy life for every minute spared between the onset of their stroke and when they first received treatment, on average.

"Every 15 minutes you wait, you lose a month of life," Dr. Atte Meretoja told Reuters Health.

Meretoja is the study's lead author from the Melbourne Brain Centre at the Royal Melbourne Hospital in Parkville, Australia.

The exact ratio of saved treatment time to healthy days varied by patient, he and his team found.

Although it's well known that early treatment for strokes is best, the new study helps highlight how significant even small delays can be, researchers said.

"We developed that measure so it's easy to remember and that the general public will understand it," Meretoja said.

He and his colleagues summarized their findings in the journal Stroke as, "Save a Minute, Save a Day."

There is currently only one treatment approved by U.S. regulators for ischemic strokes, which are caused by blockages in blood vessels going to the brain. Usually, the blockage is a result of clotted blood or fatty deposits known as plaque.

Thrombolysis is the use of a drug known as tissue plasminogen activator, or tPA, to break up the blockage and allow blood to flow to the brain. Restoring blood flow prevents the death of brain cells and improves people's recovery.

The treatment is time sensitive, however. The 60 minutes from the onset of a stroke is often referred to as the "golden hour" for treatment, because people treated during that time have much better odds of completely recovering.

Approximately 800,000 people in the U.S. have strokes every year, according to the Centers for Disease Control and Prevention. About 87 percent of those are ischemic strokes.

For the new report, the researchers compiled data from two studies to find how time to treatment is related to how patients fare after a stroke.

The studies, from Finland and Australia, included 2,258 stroke patients.

On average, the researchers found that
