SARS-CoV-2, the virus that causes COVID-19, can directly infect the arteries of the heart and cause the fatty plaque inside arteries to become highly inflamed, increasing the risk of heart attack and stroke, according to a study funded by the National Institutes of Health. The findings, published in the journal Nature Cardiovascular Research, may help explain why certain people who get COVID-19 have a greater chance of developing cardiovascular disease, or if they already have it, develop more heart-related complications.

Blood Clotting Proteins Might Help Predict Long COVID Brain Fog

Published September 1, 2023

Published by: Scientific American
Published on: September 1, 2023
By Sara Reardon

Many people who have long COVID—a condition in which health issues persist months after infection—report struggling with “brain fog,” recurring memory and concentration lapses that make it difficult to function in everyday life. Now a new study has found these cognitive problems could result from blood clots triggered by infection, possibly through mechanisms like those that cause some types of dementia. These clots leave telltale protein signatures in blood, suggesting that testing for them could help predict, diagnose and possibly even treat long COVID.

Long COVID is debilitating children. Doctors worry there aren’t enough centers to treat them

Last month, the National Institutes of Health updated its considerations for long COVID to say the burden of the condition in children “may be quite large.” Studies estimating its prevalence in pediatric populations are limited and conflicting, estimating up to 25% of children infected with the SARS-CoV-2 virus could go on to develop long COVID, though it’s more likely between 2% and 10%. Older children with existing chronic diseases or who had a more severe COVID-19 infection have an increased risk.
