Mitochondrial Damage
Kevin analyses a scientific article from the Korea Brain Research Institute where he used to work (the first article in the tweet below). The spike is cytopathic and degrades (among other things) mitochondrial cells. The second article is about how the spike induces mitochondrial proton/electron leak and iron overload leading to cachexia, aging, endothelial and cardiovascular pathologies. It does not look good especially if your mitochondria are already compromised.
