Matrix Metalloproteinase-9 (MMP-9), MMP-2, and Serum Elastase Activity Are Associated With Systolic Hypertension and Arterial Stiffness

Abstract

Aortic stiffness is related to MMP-9 levels and SEA, not only in ISH, but also in younger, apparently healthy individuals. This suggests that elastases including MMP-9 may be involved in the process of arterial stiffening and development of ISH. The relationship between arterial stiffness and elastase activity was examined in isolated systolic hypertension (ISH), and separately in a large cohort of healthy individuals. Aortic stiffness is related to MMP-9, not only in ISH, but also in healthy individuals, suggesting elastases may be involved in the process of arterial stiffening and the development of ISH.
