Los fármacos antiplaquetarios y anticoagulantes desempeñan un papel fundamental en el tratamiento de los síndromes coronarios agudos, ya que la trombosis coronaria es el proceso que los desencadena. A su vez, el intervencionismo coronario percutáneo, el tratamiento de elección en un gran porcentaje de pacientes con este síndrome, supone también un potente estímulo para la activación de las plaquetas y de la coagulación.

En este artículo se describe brevemente la activación y agregación plaquetarias y la activación de la coagulación. También se analizan los fármacos antitrombóticos utilizados en el intervencionismo coronario percutáneo y se describen sus mecanismos de acción, dosis, indicaciones y efectos secundarios, en pacientes con cardiopatía estable e inestable.

Palabras clave:
Antagonistas de los receptores de la glucoproteína IIb/IIIa

Since acute coronary syndrome results from coronary thrombosis, antiplatelet and anticoagulant drugs play a fundamental role in its treatment. Moreover, percutaneous coronary intervention, the preferred form of treatment in a large percentage of patients with this syndrome, is also a potent stimulator of platelet activation and blood coagulation. In this article, the mechanisms of platelet adhesion and aggregation and of blood coagulation are reviewed briefly. In addition, there is also a review of the antithrombotic drugs used in percutaneous coronary intervention, which includes their mechanisms of action, dosages, indications, and side-effects in patients with both stable and unstable coronary artery disease.

Key words:
Glycoprotein IIb/IIIa antagonist
