There is life in the Blood! (vessel that is)
Old Gospel song is right, but the blood has to do it's job
My senior surgical teacher CPP sent me a superb substack article I will get down to further in this post. But first of all, let’s do a little cruise down the blood vessel from the inside.
Certainly the blood carries not only red blood cells (RBCs) that are full of hemoglobin which only 7 microns across, offload their oxygen rich oxyhemoglobin O2 load out of the RBC, and across the membrane of the capillaries as they course through ALL tissues in the body. Clearly sensitive tissues like brain, heart muscle need that to work well. The RBCs literally line up single file and go through the capillary and the outside of the RBC rubs along the cellular layer of the capillary (endothelium) and the exchange occurs. There is a whole symphony going on with concomitant loading of CO2 back into the capillary in the dissolved state - into the serum surrounding the RBCs. Ditto everything else… proteins, medications, metals, etc. So that delicate balance relies on the thin wall of the vessel being healthy. This can be thrown awry by abnormal red cells, filled with hemoglobin which does not deform normally, so that red cell instead of being like a round baseball, is pushed through sideways like a 7 micron deflated football… thus “sickle cell anemia”. We are fearfully and wonderfully made, but things can go awry.
The spike protein is a toxin to the endothelial cells. They are damaged often beyond repair. In the heart it leads to myocarditis which is an inflammation on the surface of the heart.. In the brain… well, read the article below.
As a cardiac surgeon, let me try to simply explain that when we see heart attacks, we find the damage is to the inside of the heart muscle (endocardium). Known as a subendocardial scar it is classic. The basis for coronary artery bypass grafting is that the blood vessels feeding the heart lie on the epicardial (outside) surface. While small (1.5 to 2.5 mm) they are amenable to bypass grafting downstream (distal) to cholesterol blockages in the vessels. Thus a “two vessel or three vessel bypass etc.” Fortunately medicine advanced and many of these blockages can be opened up with a catheter and balloon and held open with a stent.
On the surface of the heart, we had seen occasionally - inflammation - usually caused by a virus eg coxsakie virus or just simply from opening the chest, and then opening the pericardial sac around the heart. That myocarditis usually resolves quickly with medication. Then along comes COVID experimental vaccinations and we see a huge explosion in the numbers of myocarditis in young males especially. Instead of a heart attack on the inside of the heart from blockages in flow, the surface damages seem to be caused by damage to the vessel endothelium on the surface vessels of the heart. That damage is an inflammatory change in the endothelial wall (same as happens in brain) and then the delicate balance of blood flow, oxygen delivery, etc is thrown awry. We doctors can note these change on MRI cardiac scans especially. This is the test that some doctors have suggested be applied to commercial pilots to identify those at risk for sudden cardiac event while flying.
The experimental mRNA vaccines seem to turn on the body to make the dangerous antigen we know as spike protein - it circulates and causes the damage (in the heart and brain)
Now the bigger story about the brain is well documented below… enjoy.
