Strokes: why prevention and action are the best medicine
This may seem obvious, but it’s true: No one wants to have a stroke. It’s the fourth leading cause of death in the U.S. and a significant cause of adult disability. That’s why taking steps to prevent a stroke is so important.
If you or anyone you know experiences one or more of the following symptoms, call 911 and ask for Riverside right away:
- Sudden severe headache with no known cause.
- Sudden numbness or weakness of the face, arm or leg, especially on one side of the body.
- Sudden confusion, trouble talking or understanding speech.
- Sudden trouble seeing in one or both eyes.
- Sudden dizziness, trouble walking, or loss of balance or coordination
If you suspect you or someone else is having a stroke, think F.A.S.T.
- Face drooping.
- Arm weakness.
- Speech difficulty.
- Time to call 911.
F.A.S.T. also reminds you that stroke is an emergency and you need to get help quickly.
Why do you need help quickly?
As soon as blood flow is blocked, cells in the brain start to die because they aren’t getting the oxygen and blood they need to survive. Dead brain cells can’t be brought back to life.
Damage from the most common type of stroke can often be stopped by a medication called Alteplase IV r-tPA, which can bust open a clot. But it must be given within a three-hour window. To leave time for evaluation and diagnosis, someone having a stroke must get to a hospital within 60 minutes of when they first started having symptoms.
An emerging field that holds great potential to improve stroke outcomes is now being used by Riverside. Riverside’s ER is now using Viz.ai software to better diagnose stroke upon a patient’s arrival in the ER. The platform allows multiple providers to review CT scans in real-time for more accurate diagnoses, personalized treatments, and more efficient use of resources. Before using Viz.ai software, patients with strokes would undergo CT scans and wait for providers to review in a chain of approvals from radiologists to neurologists to ED physicians.
With the new Viz.ai software, the Riverside ER, the only ER in the region using this software, can now diagnose patients with strokes much quicker, allowing for patients to remain in the community without the need for lost time and costly transportation to another care facility.
Keeping your heart and blood vessels healthy is very important if you want to lower your risk of a stroke. Many heart diseases, such as atrial fibrillation, increase your stroke risk.
