Plasminogen activator inhibitor type 1 in ischemic cardiomyopathy.
نویسندگان
چکیده
Plasminogen activator inhibitor type 1 (PAI-1) is a proteinase inhibitor1 constituting the key regulator2 of the activity of the fibrinolytic system, an important protective mechanism against thrombosis. Because a reduced fibrinolytic activity, mainly caused by increased plasma levels of PAI-1, was a common finding in cross-sectional studies of patients with coronary artery disease (CAD),3 high PAI-1 levels have been regarded as a risk factor for recurrent myocardial infarction (MI).4–6 It has also been proposed that a reduced fibrinolytic activity may have a role in atherosclerotic plaque formation and in a prothrombotic state, carrying an increased risk of arterial occlusion. Accordingly, over the last few years, several studies have been performed to investigate the role of plasma PAI-1 levels in the development of CAD and MI. Moreover, the observation that polymorphisms of the PAI-1 gene exist, some of which apparently associated with increased plasma PAI-1 levels, stimulated studies aiming at investigating the potential relation between PAI-1 genotypes and ischemic cardiomyopathy. Thus, we shall focus on recent advances in the knowledge of the role of PAI-1 and its gene in the development of ischemic cardiomyopathy.

Serum Level of Plasminogen Activator Inhibitor Type-1 in Addicted Patients with Coronary Artery Disease
Background: Plasminogen activator inhibitor-1 (PAI-1) is a glycoprotein with inhibitory effects on the formation of plasmin from plasminogen by plasminogen activator. Thus, it prevents clot lysis in vessel walls. Several evidences prove the relationship between coronary artery disease and response to fibrinolytic therapy in patients with myocardial infarction with PAI-1 level. Opium addiction i...
