abstract:BACKGROUND:Aging is a major risk factor for the development of arterial stiffness and vascular disease, and it is related to the upregulation of matrix metalloproteinase-2 (MMP-2) in the aorta of rats and nonhuman primates. This study aimed to determine whether MMP activity in the human vasculature changes with aging. ...
