Blood pressure reduction and tissue-type plasminogen activator release.
Hypertension is associated with increased risk of thrombotic events including myocardial infarction and stroke. The endothelium plays an important role in limiting intravascular thrombosis, inhibiting coagulation and platelet aggregation, and promoting fibrinolysis. Hrafnkelsdottir et al1 have previously described impaired vascular tissue-type plasminogen activator (t-PA) release in individuals...
متن کاملTissue-type plasminogen activator release: new frontiers in endothelial function.
Tissue-type plasminogen activator (t-PA) is a pivotal enzyme in the mammalian fibrinolytic system. It exerts its action by converting the zymogen plasminogen into the proteolytically active serine protease plasmin, which, in turn, degrades fibrin clots. Because of its affinity for fibrin, t-PA is the prototypic fibrin-specific plasminogen activator (1). This specificity and its lack of antigeni...
متن کاملEndothelial Tissue-Type Plasminogen Activator Release in Coronary Heart Disease
Objectives. We sought to examine whether the disturbed fibrinolytic system in patients with an acute coronary syndrome is associated with a reduced endothelial fibrinolytic capacity. Background. Intracoronary thrombus formation is a frequent finding in acute coronary syndromes. Systemic alterations of coagulation and fibrinolysis are known to occur, but possible disturbances of endothelial fibr...
متن کاملAcute reduction of lipoprotein(a) by tissue-type plasminogen activator.
BACKGROUND Lipoprotein(a) [Lp(a)] is a low density lipoprotein-like particle whose apolipoprotein B (apo B) moiety is disulfide-linked to apo(a), a plasminogen-like inhibitor of fibrinolysis in vitro. We hypothesized that plasma concentrations of Lp(a) are acutely affected by intravenous tissue-type plasminogen activator (t-PA). METHODS AND RESULTS Patients with unstable angina were randomize...
متن کاملHuman tissue-type plasminogen activator.
Tissue-type plasminogen activator (t-PA ) plays an important role in the removal of intravascular fibrin deposits and has several physiological roles and pathological activities in the brain. Its production by many other cell types suggests that t-PA has additional functions outside the vascular and central nervous system. Activity of t-PA is regulated at the level of its gene transcription, it...
