'Covid-19 Is Creating a Wave of Heart Disease' 163
Haider Warraich, a cardiologist, writing for the New York Times: An intriguing new study from Germany offers a glimpse into how SARS-CoV-2 affects the heart. Researchers studied 100 individuals, with a median age of just 49, who had recovered from Covid-19. Most were asymptomatic or had mild symptoms. An average of two months after they received the diagnosis, the researchers performed M.R.I. scans of their hearts and made some alarming discoveries: Nearly 80 percent had persistent abnormalities and 60 percent had evidence of myocarditis. The degree of myocarditis was not explained by the severity of the initial illness.
Though the study has some flaws, and the generalizability and significance of its findings not fully known, it makes clear that in young patients who had seemingly overcome SARS-CoV-2 it's fairly common for the heart to be affected. We may be seeing only the beginning of the damage. Researchers are still figuring out how SARS-CoV-2 causes myocarditis -- whether it's through the virus directly injuring the heart or whether it's from the virulent immune reaction that it stimulates. It's possible that part of the success of immunosuppressant medications such as the steroid dexamethasone in treating sick Covid-19 patients comes from their preventing inflammatory damage to the heart. Such steroids are commonly used to treat cases of myocarditis. Despite treatment, more severe forms of Covid-19-associated myocarditis can lead to permanent damage of the heart -- which, in turn, can lead to heart failure.

Interesting thought. If that's true, then that seems somewhat similar to the idea of good vs. bad bacteria, in terms of the effect that the bacteria has on human health. Like you suggest, for either bacteria or viruses, it may be very challenging to show long-term causal effect.

To be fair, there is more reason than usual to be concerned about COVID-19 with respect to the heart.

The study specifically addresses this concern: "In this cohort study including 100 patients recently recovered from COVID-19 identified from a COVID-19 test center, cardiac magnetic resonance imaging revealed cardiac involvement in 78 patients (78%) and ongoing myocardial inflammation in 60 patients (60%), which was independent of preexisting conditions, severity and overall course of the acute illness, and the time from the original diagnosis."
Of course, the other way to think about this is that if 60% of patients had myocardial inflammation, either the virus has a predilection to infecting patients with preexisting conditions or 60% of the general population has myocardial inflammation. Either idea would be non-obvious and interesting to investigate further.

However, that's a perfectly understandable limitation. The point of this study wasn't to offer a definitive conclusion. It was to look for questions that need further investigation.

This is hardly surprising. Having a cold often times causes myocarditis. Probably most of the time actually. A flu, such as Covid-19 is just about a guarantee that the patient will have it.
It's also well known (in the cardiology community) that you should not exercise or even elevate your heart-rate when you have myocarditis. Doing so has a high risk of causing permanent damage to the myocardium. The risk probably goes up with age, but even young healthy people are at risk.
I remember 15 years ago seeing an exam from a 22 year old Marine who had the flu and couldn't get over the fatigue. It ended up that he kept working out and caused enough damage to his heart that his LV EF (heart function) was only 12%. I think in the end it recovered to around 20%. But he should have had an LV EF of around 70%.
Full disclosure, I know two of the authors on this paper.

Out of curiosity, what is considered an elevated heart rate in the context of mycarditis (or having the flu)? 100 bpm? 120 bpm? 140 bpm?

Covid also increased the chance of heart disease and obesity in those that didn't get it.

That's me. In March I got a slight fever, throat pain, loss of smell, some coughing. Went away after ten days. I was in home office and hardly did anything back then but a while later I noticed some serious weakness and persisting shortness of breath. Now I'm diagnosed with Atrial fibrillation and Myocarditis. Even climbing a single flight of stairs is hard work now. Well, at least I have antibodies now and can't get Corona again! But honestly I would have preferred to never have caught it.

Own exhaust = CO2.
Wearing a mask is nothing compared to simply being indoors. CO2 indoors typically builds up to between 2x and 5x due to exhalation without exceedingly good ventilation.
Wearing a mask doe not cause you to breath in your own exhaust, it's simply not big enough, it's a barrier not a balloon. A breath is about half a litre. Masks don't stop air, they filter it. If masks stopped breath then you've faint and then die.
Or are you being absurd deliberately? Could you explain how mask wearing is don

Have you checked with Texas to make sure they're cool with that?
Did you also check if everyone wants to move to Texas?
Re: (Score:2)
No need! Everyone wants to move to Texas. Just the fact that you can then say "I'm a TEXAN" is more than enough. Anyone who does not think so already just hasn't had the chance to be a Texan yet.
