Since 2009, 38,600 stroke patients have reached hospital within 3 hours of symptoms appearing, improving their recovery chances, Public Health England (PHE) has revealed.
In 2009 PHE launched its "Act FAST" campaign to highlight symptoms of strokes and mini strokes and encourage people to call 999 if they or others experience such symptoms.
Since the campaign launched 4,000 less people have been disabled as a result of having a stroke.
A mini stroke has similar symptoms to a full stroke, although they last for a shorter time, 20% of those who have a mini stroke have a full one within days.
Research for PHE found that while 59% of people put having a stroke in the top three conditions which concerned them, 45% would call 999 if they had symptoms of a mini stroke.
Symptoms include the face falling on one side, slurred speech and being unable to raise both arms and hold them there.
This year's campaign is targeting people from African, Caribbean and South Asian communities, who according to PHE are twice as likely to be at risk of a stroke.
The campaign will consist of TV, online, radio and press advertising.
There are around 152,000 strokes in the UK annually, and 1.2m people living with the effects of stroke.
Nikki Hill, deputy director of external affairs at the Stroke Association, said: "We know that sadly, far too many people dismiss their early warning signs of stroke and delay calling 999. Stroke is a medical emergency and getting the right treatment fast can save lives."
"Through this latest campaign we hope as many people as possible know how to act FAST and help reduce the devastating impact a stroke can have."
