In 17 human thoracic aorta samples, elastin stiffness, straightness, and lamellar length decreased significantly with age in males (p < 0.05) but not females.In 17 human thoracic aorta samples, elastin stiffness, straightness, and lamellar length decreased significantly with age in males (p < 0.05) but not females.
Ex vivo tests in young and old mice showed that intact perivascular fat increased aortic stiffness only in older animals, alongside higher fat collagen levels.Ex vivo tests in young and old mice showed that intact perivascular fat increased aortic stiffness only in older animals, alongside higher fat collagen levels.
