Decreased Plasminogen Activator Inhibitor and Tissue Metalloproteinase Inhibitor Expression May Promote Increased Metalloproteinase Activity with Increasing Duration of Human Atrial Fibrillation

Abstract: Human atrial fibrogenesis is enhanced with increasing duration of AF: a longer AF duration is associated with elevated atrial interstitial MMP activity, but decreased PAI and TIMP expression.

“…Plasminogen activator inhibitor, an inhibitor of a potent activator of many MMPs in the right atrial appendages, was significantly decreased with increasing duration of AF. In parallel, the levels of TIMP-1 and -2 transcripts also decreased significantly [219]. Recently, gene expression profiles in canine models of AF were reported by Cardin et al [223].…”

“…Atrial interstitial fibrosis, degradation of the myofibril structure and the apoptosis of atrial myocytes are the main features of ASR [36,37]. Gramley et al [38] noted that atrial fibrosis increases with the duration of AF. This process is only partly reversible and thus contributes to sustaining AF once atrial fibrosis is established [39].…”

ММП є сімейством структурно і функціонально гомогенних протеолітичних ферментів, ре гулюють функцію ПM і можуть відіг-равати визначальну роль у структурному ремоделюванні передсердь, що беруть участь у розвитку та підтримці ФП [13].
