Introduction for Patients

Atrial Fibrillation, or AFib, is a type of irregular heart beat in the upper chambers of the heart (the atria). As a part of this irregular function, clots may form in those upper chambers. Blood clots can then travel to other parts of the body, including the brain, and cause a stroke (sometimes known as a “brain attack”). Strokes are one of the most serious risks for people with atrial fibrillation.

Medicines that help prevent blood clots, “anticoagulants” or “blood thinners”, can reduce this risk of stroke. In the past, warfarin (Coumadin) was the only blood thinner available. Over the past several years, four additional blood thinners have become available. Each of these medicines has pros and cons. Only you and your health care provider can determine which one is best for you.

We will now ask you several brief questions. These questions will help determine which blood thinner may be best for you based on your personal health history and your preferences for the different anticoagulant options.
