Matrix metalloproteinases (MMPs) include most major constituents of the arterial wall as substrates. A common promotor polymorphism (5A/6A) is associated with differences in MMP-3 (stromelysin-1) activity, and associations with certain forms of vascular disease have been shown. This study investigated whether the MMP-3 5A/6A promoter polymorphism contributes to age-related large artery stiffening.

Background: The stiffness of the aorta is known to increase with increasing age and in the presence of CAD. However, little is known about the mechanics of coronary arteries, which may have important clinical consequences.
