COVID ages women’s blood vessels, according to a study

COVID-19 causes women’s blood vessels to age prematurely, according to an international study involving two researchers from Université Laval. The disease should therefore be considered an additional risk factor in cardiovascular health analyses. Specifically, in those who have developed severe symptoms, they warn.

The aging of blood vessels results in greater rigidity, which can increase the risk of certain cardiovascular diseases.

“The heart must work a little harder to propel blood through the arterial system, and this causes variations in pressure that can damage sensitive organs, including the brain and kidneys,” explains Catherine Fortier, a kinesiologist and researcher in vascular aging at the CHU de Québec-Université Laval.

Researchers use a specialized brain imaging technique to identify a potential biomarker and therapeutic target of Long COVID

Long COVID is a chronic condition that causes cognitive problems known as “brain fog,” but its biological mechanisms remain largely unclear. Now, researchers from Japan used a novel imaging technique to visualize AMPA receptors—key molecules for memory and learning—in the living brain. They discovered that higher AMPA receptor density in patients with Long COVID was closely tied to the severity of their symptoms, highlighting these molecules as potential diagnostic biomarkers and therapeutic targets.
