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).”

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.”

Latest paper from Dr Robin Kerr & me: #LongCovid is primarily a Spike protein Induced Thrombotic Vasculitis https://researchsquare.com/article/rs-2939263/v1 Here we proposed that long covid is primarily a spike protein-induced thrombotic vasculitis, & we use Robin as a supporting case study 🧵 #TeamClots

SARS Covid-19 as an immunothrombotic disease and the potential benefits of a new estrogen-free contraceptive containing drospirenone.
"As Covid-19 is considered an immunothrombotic disease, the potential benefits of estrogen-free contraceptives like drospirenone are discussed. Adding estrogens in contraception may rise the cardiovascular risk in Covid-19 and Long Covid patients."

“A study from Houston Methodist found some #LongCovid patients aren't getting enough blood to their heart.. The ability of endothelial cells, which play a key role in dilating arteries.. was diminished by 20% among 101 long covid patients who participated”
