ABSTRACT

We measured C-reactive protein concentrations in 31 patients with interventional procedures after blocking thrombosis in 17 of them by the administration of a 12 hour long infusion of eptifibatide in order to evaluate the role of arterial thrombosis. There were no differences in C reactive protein concentration between the treated and control group pre-angioplasty (0.32 0.4 vs 0.56 0.57 md/dl; p = NS), nor post-angioplasty (0.35 0.42 vs 0.53 0.5 mg/dl, p = Ns). The eptifibatide group maintained basal C reactive protein concentrations 6 hours after the procedure, while the control group had a significant increase (0.43 0.5 vs 1.02 0.89 mg/dl; p < 0.05). There was a decrease in C reactive protein 24 hours after angioplasty in eptifibatide group (0.24 0.27 vs 1.34 0.89 mg/dl; p < 0.001), but it increased again 48 hours after the procedure although to a lesser extent than in the control group (0.57 0.55 vs 2.18 2.1 mg/dl; p < 0.05). Eptifibatide, a synthetic peptide which is a selective blocker of the platelet GP IIb/IIIa receptor significantly reduced C-reactive protein concentration after angioplasty.

ABSTRACT

Para evaluar el papel de la trombosis arterial en la elevación de la proteína C reactiva determinamos los valores en suero de este marcador de inflamación en 31 pacientes con angioplastia coronaria. En 17 pacientes se bloqueó la generación de trombina mediante eptifibatide durante 12 h. No se apreciaron diferencias entre el grupo tratado y el grupo control, preangioplastia (0,32 ñ 0,4 frente a 0,56 ñ 0,57 md/dl; p = NS) ni postangioplastia (0,35 ñ 0,42 frente a 0,53 ñ 0,5 mg/dl; p = NS). A las 6 h posprocedimiento, el grupo tratado mantuvo constantes los valores de proteína C reactiva, mientras que el grupo control presentó ya cifras significativamente mayores (0,43 ñ 0,5 frente a 1,02 ñ 0,89 mg/dl; p < 0,05). A las 24 h se redujo la concentración de proteína C reactiva en el grupo con eptifibatide (0,24 ñ 0,27 frente a 1,34 ñ 0,89 mg/dl; p < 0,001), pero a las 48 h se elevó de nuevo, aunque en menor grado (0,57 ñ 0,55 frente a 2,18 ñ 2,1 mg/dl; p < 0,05). El eptifibatide redujo signficativamente los valores de proteína C reactiva postangioplastia (AU)
