What can be done to reduce the risk of stroke for people with Atrial Fibrillation?

In terms of atrial fibrillation causing stroke, it used to be tablet therapy. Are there other things that you do in your specialty now for atrial fibrillation? So of course the important thing is that we have very good treatment now to protect from the stroke risk in atrial fibrillation. We have anticoagulants, traditionally warfarin, but now some newer agents which are more effective and safer and they can almost completely eliminate that risk of stroke. So it's very important to make the diagnosis and if... So it's very important to make the diagnosis and if the stroke risk is sufficiently great, start patients on these anticoagulants to keep their blood thin and protect them from stroke. Can you treat the actual atherofibrillation itself? So, in terms of the atrial fibrillation itself, if the patient has sufficient symptoms, we do have some treatments. Traditionally, we've used drugs, anti-arrhythmic drugs, which can be effective at suppressing the tendency to atrial fibrillation, but over the last 15 years, we've developed a procedure called ablation that can be curative of atrial fibrillation. We're continuing to develop the ablation procedure and perfect it all the time, trying to make it more effective and safer, because it's not without its risks and therefore we use it in selected and appropriate patients.
