UNIVERSITY PARK, Pa. — Penn State Health stroke experts say new guidelines extend clot‑busting treatment to 24 hours after a stroke, offering critical benefits for patients who experience a stroke while asleep.
When physician Jeffrey Rajchel got up in the middle of the night to use the restroom in 2022, he never imagined he would have a stroke. At 72, he was in excellent physical shape — he didn’t smoke, maintained a healthy weight and was training to compete in a national-level seniors’ tennis tournament. But that night, he collapsed on the bathroom floor and couldn’t reach his phone to call his wife, a nurse.
By the time she found him in the morning, Rajchel had passed the then-standard 4.5-hour window to receive clot-busting medication. After being rushed to Penn State Health Milton S. Hershey Medical Center, he found the stroke had left him with a significant loss of movement and control on his dominant left side.
He chose to get a vagus nerve stimulator implant, a device that sends mild electrical pulses to a nerve, strengthening the brain’s ability to rewire during rehabilitation. The nerve stimulator, paired with physical therapy, has helped him regain some hand function.
Looking back, Rajchel said he believes earlier treatment would have given him a better outcome.
“If I had been able to receive the [clot-busting] medication, I’d be living a very different life right now,” he said.
However, starting in January 2026, patients who experience an acute ischemic stroke, as Rajchel did, now have a longer window of time to receive treatment for ischemic stroke, said Alicia Richardson, Penn State Health System stroke director.
The 2026 Guideline for the Early Management of Patients with Acute Ischemic Stroke, published by the American Stroke Association, expands treatment options for a condition that affects more than 795,000 people in the U.S., according to the Centers for Disease Control and Prevention. Stroke remains the fourth-leading cause of death in this country.
What is a stroke?
An acute ischemic stroke happens when a blood clot blocks blood flow within the brain. Without oxygen, brain cells quickly begin to die.
A simple way to remember stroke symptoms is BEFAST:
- B – Sudden loss of balance
- E – Sudden eyesight changes
- F – Facial drooping
- A – Arm weakness
- S – Speech difficulty, both understanding and speaking
- T – Time to call 911
