Stay Safe, People

Here’s the article:

From very early in the pandemic, it was clear that SARS-CoV-2 can damage the heart and blood vessels while people are acutely ill. Patients developed clots, heart inflammation, arrythmias, and heart failure.

Now, the first large study to assess cardiovascular outcomes 1 year after SARS-CoV-2 infection has demonstrated that the virus’ impact is often lasting. In an analysis of more than 11 million U.S. veterans’ health records, researchers found the risk of 20 different heart and vessel maladies was substantially increased in veterans who had COVID-19 1 year earlier, compared with those who didn’t. The risk rose with severity of initial disease and extended to every outcome the team examined, including heart attacks, arrhythmias, strokes, cardiac arrest, and more. Even people who never went to the hospital had more cardiovascular disease than those who were never infected.

The results are “stunning … worse than I expected, for sure,” says Eric Topol, a cardiologist at Scripps Research. “All of these are very serious disorders. … If anybody ever thought that COVID was like the flu this should be one of the most powerful data sets to point out it’s not.” He adds that the new study “may be the most impressive Long Covid paper we have seen to date.”

Others agree the results of the study, published in Nature Medicine on 7 February, are powerful. “In the post-COVID era, COVID might become the highest risk factor for cardiovascular outcomes,” greater than well-documented risks such as smoking and obesity, says Larisa Tereshchenko, a cardiologist and biostatistician at the Cleveland Clinic, who recently conducted a similar, much smaller analysis. She cautions that the new study will need to be replicated, and that it was retrospective, possibly introducing inaccuracies such as incorporating faulty diagnoses from patient records. “It looked back. We have to do prospective studies to calculate accurate estimates.”

Nor do researchers know how the virus orchestrates this long-term damage. But they think the cardiovascular risks and the constellation of symptoms collectively known as Long Covid (which include brain fog, fatigue, weakness, and loss of smell) could have common roots.

“This is clearly evidence of long-term heart and vascular damage. Similar things could be happening in the brain and other organs resulting in symptoms characteristic of Long Covid, including brain fog,” says senior author Ziyad Al-Aly, a clinical epidemiologist at Washington University in St. Louis and chief of research at the VA St Louis Health Care system.

More at the link. The people studied were mostly older white men so there is more work to be done to see if this holds up for the rest of the population. But let’s just say it’s not exactly good news in any case.

Everyone is going to have their own tolerance for risk and people have different circumstances, age, general health etc that guide their decisions. But it seems to me that this meme of “I’m just going to get it and get it over with” isn’t a great idea. We just don’t know what the long term ramifications are yet. Maybe vaxxed people who get a mild case of COVID, or younger folks, don’t suffer these consequences but we just don’t know yet. I wouldn’t throw away your N95s just yet.
