Atrial fibrillation (AFib) not caused by a heart valve problem is a type of irregular heartbeat that was estimated to affect approximately 6.4 million people in the U.S. in 2014. AFib not caused by a heart valve problem puts people at a 5 times greater risk for stroke. The Bristol-Myers Squibb and Pfizer Alliance is challenging you to learn the fibs and the facts about AFib-related stroke risk, and share them with everyone you care about.

The more people we reach with this quiz, the more people we can help understand the connection between AFib, blood clots and stroke. Since 2013, Fibs or Facts has raised $35,000 for National Stroke Association – so this year we're going for $30,000 more!

For every quiz completed, $1 will be donated
