For iron build-up, yes, there have been many discussions about chelation. I personally use green tea supplements. There is some research to support that they can chelate across the blood brain barrier.
But for myself, I am not sure that iron build-up is the biggest problem. My main issue is fatigue -- really bad fatigue -- and I'm thinking I'll see some relief once my bilateral jugular obstruction gets taken care of.
I agree, the recent death is a real blow. When I first joined here, it was not long after the events at Stanford. Since then, we haven't had another report of a stent migration and emergency heart surgery, but that doesn't mean it couldn't happen again. Proceed with caution, avoid stents, avoid overseas travel, is what I took from it.
