Platelet glycoprotein IIb/IIIa receptor antagonists in cardiovascular disease.
CONTEXT Thrombus formation on disrupted atherosclerotic plaque is the major cause of acute coronary events. Platelet inhibitors are the mainstay of drug therapy to reduce cardiac events in patients with acute coronary syndromes. The platelet glycoprotein (GP) IIb/IIIa receptor is the final common pathway of platelet aggregation. OBJECTIVES To review mechanisms of platelet activation and aggre...
متن کاملPlatelet glycoprotein IIb/IIIa antagonists: pharmacology and clinical developments.
PLATELETS are critical for normal hemostasis and thrombus formation. Thrombus formation initiated by platelets plays a central role in the pathogenesis of acute coronary syndromes (unstable angina and myocardial infarction). Platelets are involved in events causing angioplasty failure and stent thrombosis and may also play an important role in restenosis through the release of potent prothrombo...
متن کاملAcquired thrombasthenia due to inhibitory effect of glycoprotein IIbIIIa autoantibodies.
BACKGROUND A 75 year old patient presenting with mucocutaneous bleeding was diagnosed with acquired thrombasthenia. The diagnosis was based on lack of platelet aggregation with adenosine diphosphate (ADP), arachidonic acid and collagen, and normal aggregation induced by ristocetin. OBJECTIVE To study the mechanism of platelet function inhibition in a patient with acquired thrombasthenia. ME...
متن کاملMedical decision making with incomplete evidence--choosing a platelet glycoprotein IIbIIIa receptor inhibitor for percutaneous coronary interventions.
BACKGROUND Medical decision making must often be performed despite incomplete evidence. An example is the choice of a glycoprotein IIb/IIIa (GP2b3a) inhibitor, a class of potent antiplatelet medications, as adjunctive therapy during percutaneous coronary interventions (PCIs). GP2b3a inhibitor efficacy in reducing adverse outcomes has been well documented with multiple placebo-controlled randomi...
متن کاملGlycoprotein IIb/IIIa antagonists
The role of GP IIb/IIIa antagonists has been focused on patients with acute coronary syndromes undergoing PCI. In the ISAR-REACT 2 study abciximab given in patients with NSTEACS undergoing PCI already treated with 600 mg clopidogrel improved 30-day death and reinfarction rate in troponin positive patients. In the large EARLY-ACS trial upstream therapy with eptifibatide in high risk with NSTE-AC...
