FAST & Direct: Recognizing Stroke and Heart Attack in the US

In a cardiovascular emergency, every second counts. Recognizing the signs early can save a life and prevent permanent disability. This guide aligns with American Heart Association (AHA) recommendations.

Think FAST for Stroke

The AHA recommends the FAST test to quickly identify the signs of a stroke:

F
Face Drooping

Does one side of the face droop or feel numb? Ask the person to smile — is it uneven?

A
Arm Weakness

Is one arm weak or numb? Ask them to raise both arms — does one drift downward?

S
Speech Difficulty

Is speech slurred or hard to understand? Can they repeat a simple sentence correctly?

T
Time to Call 911

If any of these signs are present, call 911 immediately. Note the time symptoms started.

Why Speed Matters

For stroke, clot-busting medication (tPA) can only be administered within a narrow window of time — typically within 3 to 4.5 hours of the first symptom. For heart attacks, restoring blood flow within the first hour (“the golden hour”) dramatically increases survival rates. Every minute without treatment causes approximately 2 million brain cells to die in a stroke.
