Understanding the connection between PFO and stroke
Chances are, you learned that you have a patent foramen ovale (PFO) after you had an ischemic stroke. You are not alone. Nearly half of people whose strokes have no known cause also have a PFO.
Three things you should know about PFO and stroke:
1. Having a PFO can lead to stroke.
2. One stroke increases the risk of having another stroke.
3. Closing a PFO reduces the risk of having another stroke.
