D i had a stroke two years ago and today is clear that it was caused by patent foramen ovale. can i keep doing sports like swimming, running, fitness?

Probably you can: A patent foramen oval is a hole between 2 top chambers of heart (atria) that don't close after birth (25% people). First sx is a stroke, often affecting numb or weakness one side of body, vision, balance, speech. Most rx w blood thinner to, prevent another cva, physical and ot; few surgery. U r < 50 y/o & otherwise healthy. You can do anything you put your mind to!

Probably: First, we can rarely guarantee that a stroke is caused by a pfo--20-25% of the general population has a pfo, which means that anyone who has a stroke for any reason has a 20% chance of having a pfo. That being said, the younger and healthier a patient is, the more likely it is that the pfo was related to stroke. There is no contraindication to exercise with pfo. Check with your doctor to be sure.
