ItalianoReuters artikel om att COVID är dåligt för hjärtat
| https://www.reuters.com/business/healthcare-pharmaceuticals/reinfection-severe-outcome-more-common-with-ba5-variant-virus-spike-protein-2022-07-28/ Urplock från mig: Reinfections, severe outcomes may be more common with BA.5 Compared with the earlier Omicron BA.2 subvariant, currently dominant Omicron BA.5 is linked with higher odds of causing a second SARS-COV-2 infection regardless of vaccination status, a study from Portugal suggests. [...] Moreover, the vaccines appeared to be less effective in reducing the risk of severe outcomes for BA.5 compared with BA.2. [...] Virus spike protein damages heart muscle cells The spike protein on its surface that the coronavirus uses to break into heart muscle cells also triggers a damaging attack from the immune system, according to new research. The SARS-CoV-2 spike protein interacts with other proteins in cardiac myocytes to cause inflammation, researchers said on Wednesday in a presentation at the American Heart Association's Basic Cardiovascular Sciences Scientific Sessions 2022. In experiments with mice hearts, comparing the effects of SARS-CoV2 spike proteins and spike proteins from a different, relatively harmless coronavirus, the researchers found that only the SARS-CoV-2 spike protein caused heart dysfunction, enlargement, and inflammation. [...] "We provided direct evidence that spike protein is toxic to the heart muscle cells and narrowed down the underlying mechanism as spike protein directly inflames the heart muscle cells," he told Reuters. "More work is being done in my lab to test whether and how spike protein kills heart muscle cells."
