    I think the article is referring to the hormone level in the blood serum from specifically the endothelial cell that causes dialation of the capillar blood vessel that result in better perfusion in specific organs like the heart or the kidney. So the more capillary the better the perfusion in organs and an increase capillary means lower level of that hormone ADM. This might be a good bio-marker to track for longevity. Very complicated science article.
