The Role of Capillary Health in Long COVID Recovery Long COVID affects many individuals, with symptoms linked to microclots that hinder oxygen delivery. However, new research indicates vascular injuries, such as capillary rarefaction and endothelial…

Everyone’s chasing clots, but the real damage might be hiding in plain sight inside your capillaries.

Impaired perfusion, endothelial stress, mitochondrial fallout… all in vessels you need a microscope to see.

humorous cartoon shows a doctor holding a magnifying glass over a patient’s fingernail. Inside the magnified view, red blood cells are screaming as they ride through chaotic, twisted capillaries like a roller coaster. The patient looks surprised, and the caption reads: “When Long COVID takes your capillaries on a wild ride.”

What can your fingernails reveal about Long COVID?
More than you think.

#Capillaroscopy shows tiny blood vessels and in Long COVID, they often look damaged, sluggish, or twisted.

Long COVID isn’t “just fatigue.” It’s in your blood flow.

Impaired endothelial function contributes to cardiac dysfunction: role of mitochondrial dynamics | American Journal of Physiology-Heart and Circulatory Physiology The endothelial microvasculature is essential for the regulation of vasodilation and vasoconstriction, and improved functioning of the endothelium is linked to improved outcomes for individuals with coronary artery disease (CAD). People with endothelial dysfunction exhibit a loss of nitric oxide (NO)-mediated vasodilation, achieving vasodilation instead through mitochondria-derived H2O2. Mitochondrial dynamics is an important autoregulatory mechanism that contributes to mitochondrial and endothelial homeostasis and plays a role in the formation of reactive oxygen species (ROS), including H2O2. Dysregulation of mitochondrial dynamics leads to increased ROS production, decreased ATP production, impaired metabolism, activation of pathological signal transduction, impaired calcium sensing, and inflammation. We hypothesize that dysregulation of endothelial mitochondrial dynamics plays a crucial role in the endothelial microvascular dysfunction seen in individuals with CAD. Therefore, proper regulation of endothelial mitochondrial dynamics may be a suitable treatment for individuals with endothelial microvascular dysfunction, and we furthermore postulate that improving this microvascular dysfunction will directly improve outcomes for those with CAD.
