Jag vet inte vad din hjärnkapacitet har med saken att göra, själv går jag efter forskningen. Den säger riktigt att den första Wuhan-varianten inte finns längre. Den säger också att senare varianter ger mindre symptom, och
kanske ger mindre risk för postcovid. Det sista vet man inte än. Forskning har nämligen sedan länge pekat på att också milda insjuknanden kan ge postcovid.
Nyss var det en artikel om en 19-åring som efter julhelgerna 2020, alltså före vaccineringarna. Man vet inte i vad, "Det troligaste är att Andreas drabbades av plötsligt hjärtstillestånd." Kanske är han en av de eventuellt många fallen som kommit efter pandemin.

Det tycks, som påpekats innan i tråden, finnas en våg av sådana fall före vaccineringarna. Vi vet att vaccinet kan ge hjärtproblem, men istället för att som en del här tro att vaccinet är ont och Covid-19 är gott så förstår andra av oss att ingen av dem är särskilt bra.
Och Japan Times har en artikel idag, som inleds:
If you’ve had COVID-19, watch out for stroke symptoms
Harlan Krumholz, a cardiologist at the Yale School of Medicine, says he worries about two kinds of long COVID-19.
There’s the obvious version where people suffer prolonged virus symptoms like fatigue, and a stealthier version in which people recover yet carry an added risk of blood clots and strokes.
He doesn’t want to panic people — most of us will probably be fine. But new studies confirm that some will develop an elevated risk of blood clots, strokes or heart attacks. Given that most people have had COVID-19 by now, everyone should be more vigilant about the early warning signs such as chest pain, unusual swelling, numbness, weakness or sudden changes in balance, speech or vision.
Scary reports started to surface in the spring of 2020 of young people suffering deadly strokes during or right after a COVID-19 infection. Doctors were starting to suspect COVID-19 was not just a respiratory disease but a blood vessel disease. Larger studies now back up their suspicions and showed that COVID-19 infections elevated everyone’s risk. That explained why younger people who should have had almost no risk were showing up with strokes, but they were just the tip of the iceberg. Patients who already smoked or had high blood pressure or diabetes went from high risk to even higher.
One recent study, published in the journal Heart — associated with the British Medical Journal — tracked 54,000 people in the U.K. for four and a half months and concluded that those who’d been infected were 2.7 times more likely to develop venous thromboembolism — a dangerous type of blood clot — than those who had never been infected.
The study also showed that those who got infected but were not sick enough to be hospitalized were still 10 times more likely to die of any cause during the study period than their uninfected counterparts. People who’d been hospitalized for COVID-19 were about 100 times more likely to die during the study period.
Another new study published in Neurosurgery focused on the period when people were actively infected, and concluded that COVID-19 infection was associated with strokes — and that strokes that occurred in infected people were likely to be more severe and harder to treat with surgery.
Krumholz, who I met before the pandemic through his work on improving the way doctors conduct and evaluate studies, said they still don’t have enough data to know how much these risks are mitigated by vaccination or how long the elevated risk lasts. He said the medical community has long known that viruses can leave lingering effects, but until this pandemic, it had never been studied so thoroughly.
A consensus is forming that the lasting damage is caused by inflammation — a necessary part of our immune defense system, but one that can cause harm if it remains in high gear."
Här finns också en passage om det löjliga debattläget kring detta:
Even something as neutral as heart disease risk is politicized when it intersects with the pandemic. "You can’t imagine the attacks I got,” said Jabbour, after he appeared on CNN in 2020 discussing his early observations and study results. That polarization has only deepened — with some people refusing to believe that COVID-19 can have lasting effects and others posting scare stories that the continued harsh lockdowns in China are part of a plan to triumph over the West as widespread long COVID-19 collapses our workforce.
The reality is some people have been devastated by COVID-19, even as most fully recover. It takes time, good studies and a lot of cases to get an understanding of the after-effects of infection, and that information is coming from countries that have seen the most cases. The take-home message is that even if you feel fine, past COVID-19 infection is a cardiovascular risk factor, a little like elevated cholesterol. It’s not a reason to despair, but it’s a very good reason to be vigilant.
