Is functional hyperemia reduced in skeletal muscle of aged rats?
Arteriolar tone and blood flow in resting skeletal muscle of rats is not altered with age, whereas the increases in these variables that normally accompany muscle contraction are markedly impaired during aging. Neither cyclooxygenase metabolites nor lipid peroxidation appear to be involved in this impairment.
Brain MRI findings cannot serve to suspect FD in young patients presenting with an acute cerebrovascular event. This deserves consideration in the search for possible causes of young patients with stroke.
