The Cardiac pathophysiology of Covid-19
The Cardiac pathophysiology of Covid-19

“Findings emphasize that Covid-19’s myocardial pathology predominantly arises from fibrin thrombi within the coronary MICROVASCULAR network, especially in the abluminal spaces.

➡️This pathological process leads to myocardial fibre injury, necrosis, and ischemic changes( = fibrosis), contributing to both the acute symptoms and long-term sequelae (Long Covid).”

Uptick in post-acute Covid avascular necrosis.

Just like what happened in SARS1 survivors, which was well-documented but our government chose to ignore and pretend Covid is a cold.

“‘I couldn't believe what I saw; these amyloid signals were everywhere. And I got back to the control sample and did the same, and I saw little bits, but not much.’

Pretorius had become one of the first in the world to discover that COVID-19 could induce widespread clotting in the blood of patients.”

Persistent endothelial dysfunction in post-COVID-19 syndrome and its associations with symptom severity and chronic inflammation
Persistent endothelial dysfunction in post-COVID-19 syndrome and its associations with symptom severity and chronic inflammation

Long Covid patients exhibited persistent endothelial dysfunction.

This was indicated by lower venular flicker-induced dilation (vFID), narrower central retinal artery equivalent (CRAE), and lower arteriolar-venular ratio (AVR).

“Our results demonstrate that prolonged endothelial dysfunction is a hallmark of PCS, and impairments of the microcirculation seem to explain ongoing symptoms in patients.”

Unraveling Covid’s Pernicious Role in Brain Fog and Clotting
Unraveling Covid’s Pernicious Role in Brain Fog and Clotting

“Navigating social distancing requirements that complicated lab work, Akassoglou and her collaborators conducted a series of experiments in mice to explore the pernicious role of the coronavirus’s spike protein.

They discovered that beyond serving as the virus’s “key” to enter cells, spike binds with a blood clotting factor called fibrinogen, creating structurally abnormal, inflammation-promoting clumps of fibrin — the insoluble material that forms the mesh-like structures essential for wound healing.

High levels of these abnormal clots not only push the body’s clotting system into overdrive, increasing clot formation and inflammation, but also suppress natural killer cells — the immune system’s virus-clearing soldiers.”

Fibrin ‘binds to the SARS-CoV-2 spike protein,’ forming clots that ‘drive systemic thromboinflammation and neuropathology,’ and it happens ‘independently of active infection.’

“In-depth targeted proteome investigation evidenced substantial changes in plasma protein composition of patients during and recovering from COVID-19, evidencing a wide range of functional pathways induced by SARS-CoV-2 infection. In addition, we show that a subset of acute phase proteins, clotting cascade regulators and lipoproteins could have clinical value as potential predictors of long-term cardiovascular events in COVID-19 convalescents.”
