Might be a question of cause and effect. My neurologist theorized my migraines were triggered by microemboli leaking through a PFO (leak between left and right side of the heart: normally the lungs filter this stuff out)

PFO closed, migraines basically gone.

PFO can lead to stroke too for the same reason, and that's when it's usually closed, after a stroke. Not all migraines are caused by PFO. I went on blood thinners first for a year as a test.
