You are thinking this is another version of heart disease, as if a stenosis means heart disease and everything you think you know or heard of in relation to heat disease has something to do with this and it does not necessarily have anything to do with heart issues or stenosis in cardiac arteries.
In fact, stenosis in the femoral veins that cause venous ulcers in the foot are not related to heart disease either.
The only criteria for CCSVI is that there be something hindering the outflow of the venous blood from the head. It could be anything that might cause that hindrence, in my case it was that I was born with too little space where my jugulars go by my jaw line and my jugs were pinched almost completely closed. This situation is not impacted by blood pressure.
Another way a person can have a stenosis is a scar or some type of damage to a vein that makes it stenose....if you've had chemo and they put a central line in that can cause stenosis of the jugular.
It can have something pressing on it say a tumor or another artery or vein (may thurners is an artery pressing on a vein)
Drugs that lower blood pressure will not help this because they impact arterial pressure and have little to do with the veins and certainly do not impact stenoses at all.
Arteries are where we check blood pressure it really tells us nothing about veins. They are passive as the blood returns to the heart and we do not measure the pressure in them actually.
I hope that helps!
