...). In contrast with the situation in short-term PH, endothelial dysfunction and an increase in endothelium-dependent contraction have been reported during aging. This effect of aging is mainly mediated by an increase in vasoconstrictor prostanoids [ 9 , 10 ] and/or a decrease in vasodilator factors, such as PGI...
