COVID-19 takes serious toll on heart health—a full year after recovery
Infected patients develop blood clots, heart inflammation, arrhythmias, and heart failure among others (

Detailed analysis thread on Twitter: COVID-19: Increased risk of dying from infection and sudden death
This a long thread looks at several studies on death and neurovascular injury along with a whole bunch of sudden death examples of relatively young and healthy people found by @MeetJess . 🧵1/
Persistent clotting protein pathology in Long COVID/Post-Acute Sequelae of COVID-19 (PASC) is accompanied by increased levels of antiplasmin - Cardiovascular Diabetology
"Persistent clotting protein pathology in Long COVID/Post-Acute Sequelae of COVID-19 (PASC) is accompanied by increased levels of antiplasmin"
Virtually all children infected with COVID-19 show signs of blood vessel damage, study shows
From 2020: "Virtually all children infected with COVID-19 show signs of blood vessel damage, study shows"
Expert’s warning as nearly one in four Covid patients show signs of blood clotting a year later
"Up to a quarter of patients discharged from hospital after Covid-19 treatment are still showing “unusual” blood clotting activity up to one year later."
COVID-19 and the Brain
From 2020: "Vascular events such as strokes have been reported in COVID-19 patients. It is thought that SARS-CoV-2 causes a thickening of the blood, which leads to blood clots"

1/A reminder that #LongCovid patients have microclots. We are sending children to school with no mitigations and a 5% chance of a disease that damages you blood vessels.🩸 ALL 80 patients tested in this paper had moderate microclots. Green is microclots.

What Does COVID Do to Your Blood?
The Impact of Covid-19 Blood Clots Throughout the Body:
New study offers clues as to how long COVID affects the heart | Houston Public Media
“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”
Long covid clot risk
“COVID-19 triggers a massive release of biomolecules from the immune system…these molecules can gum up the blood and make it more likely to form clots…a new study is showing that people with long COVID have a higher risk of blood clots.”
Blood-clotting imbalance persists in Long COVID, research finds
"higher levels of blood-clotting booster called von Willebrand Factor, lower levels of protein that normally breaks down VWF...blood vessels still being damaged long after the initial infection, & specific cells of the immune system were at abnormal levels
A central role for amyloid fibrin microclots in long COVID/PASC: origins and therapeutic implications
“The result, as is strongly manifested in platelet-poor plasma (PPP) of individuals with Long COVID, is extensive fibrin amyloid microclots that can persist, can entrap other proteins, and that may lead to the production of various autoantibodies.”

Typical inflammatory conditions like cardiovascular disease, diabetes etc are known to have hypercoagulation - which is a hallmark of systemic inflammation. Microclots and platelet hyperactivation are both present in these conditions. Longcovid has significantly more microclots

Patient Anecdote thread on Twitter: Today I travelled 4000miles to get tested for Microclots to test the theory that this is causing my #longcovid symptoms. Turns out I have them. This testing needs to be made accessible to all those suffering around the world so they can be treated (1)
SARS-CoV-2 Mediated Endothelial Dysfunction: The Potential Role of Chronic Oxidative Stress
"Endothelial cells have emerged as key players in SARS-CoV-2 infection and COVID-19 inflammatory pathologies. Dysfunctional endothelial cells can promote chronic inflammation and disease processes like thrombosis, atherosclerosis, and lung injury."

Plus new Epidemiology in @JAMA_current some say proves #LongCOVID is a hoax⁉️
Truth is…endothelial dysfunction plus inflammation can lead to life-altering brain & body dz.

Tiny, Menacing Microclots May Explain Long COVID’s Symptoms
“One core question is: Do these microclots actually represent a root cause, or are they in response to something else that's ongoing?” says Michael VanElzakker PhD, co-founder of PolyBio Research Foundation, which is focused on studying viral reservoir:

Anecdote: Big news: I was lucky to get tested for micro blood clots, & I have a lot of them! #LongCovid
Healthy control blood on the left. Mine on the right. The green is all microclots!
These clots are likely blocking oxygen from getting around my body & could explain many symptoms. 1/

Relative hypercoagulopathy of the SARS-CoV-2 Beta and Delta variants when compared to the less severe Omicron variants is related to TEG parameters, the extent of fibrin amyloid microclots, and the severity of clinical illness.

First evidence of inflammatory micro clots in blood of individuals suffering from Long COVID
"New research indicates that an overload of various inflammatory molecules, literally "trapped" inside insoluble microscopic blood clots (micro clots), might be the cause of some of the lingering symptoms experienced by individuals with Long COVID."

Diagnose microclots in LongCovid patients | Kernls
Develop an accessible, lab-based method to diagnose microclots in LongCovid patients Millions suffering from LongCovid don't have access to a regular test for diagnosis. Top researchers develop a widely available method to help explain the condition's debilitating symptoms.

This is starting to get frustrating ~ Another #LongCovid pt travels across the world to Germany & gets a simple blood test which reveals a clear biomarker - #MicroClots
The fact we still don’t have this simple test readily available is a failure. What are we waiting for??
