“Again, high blood pressure caused by clogging of the arteries is associated with a lot of bad things. But what if the arteries are not clogged? “
Clogged arteries are not required for high blood pressure. I have high blood pressure and my arteries are not clogged.
Arteries and veins are not like an oil gallery drilled in the block. They are living tissue and they expand and contract on their own.

Yes, high blood pressure can be caused by stiffness in the artery wall. Is that then linked by any evidence to kidney damage or heart attacks?
That is my point. They say high blood pressure causes things, but in reality it is ASSOCIATED with things. But there are multiple causes of high blood pressure. I grant high blood pressure CAUSED BY clogged arteries will do bad things. But is there any indication high blood pressure due to arterial stiffness (separate from interior calcium or plaque build-up) causes anything bad to happen?
