If the endothelial cells lining the blood vessels are damaged by expressing the spike protein gene they probably aren't able to convert plasmin to plasminogen which removes clots in the veins. The endothelial cells expressing the spike gene will attract the bodies white blood cells which attempt to cleanup the sick cell. The spike actually kills the clean-up crew, causing more of a blockage from the white blood cells.

I found this supplement which may help take over that role and may allow cleanup through the blood vessels again?https://www.supersmart.com/en/shop/cardiovascular/plasminogen-activator-0808

"Helps to unclog the arteries by preventing new plaque from forming and reducing existing deposits. High in nattokinase and d-alpha tocopherol which activate the plasminogen responsible for eliminating blood clots. Contains serrapeptase which helps break down dead cells and the accumulation of damaged tissue. Supports healthy blood flow. Contains high levels of powerful antioxidants (phosphorylated ascorbate, pterostilbene, OPCs...) which help fight cellular ageing."
