Prior to Covid, one of the bigger reasons for young persons who seem fit to have a stroke is an unidentified hole in the heart. This is a birth defect that many people never know they have until the stroke. My wife had a stroke at 45.
Best wishes for a speedy recovery for your friend.
For sure on the speedy recovery
I found out I had a hole in my heart .Interaterial shunt. The only way to identify it is an ultra sound and they pump saline into your blood while doing it. It can be seen as little bubbles passing thru that hole.Doesn't make a difference if you were vaxed or not. It is suppose to close right after birth. Mine didn't. Yep, had stroke this past July. Did it cause it? I don't know, being 79 yrs old. I take medication for high cholesterol and high blood pressure.
