Résumé
Resumen El ticagrelor es un antiagregante plaquetario que actúa a través de la unión reversible a los receptores P2Y12 de la adenosina-difosfato. En el síndrome coronario agudo, ha demostrado reducir el riesgo de eventos cardiovasculares mayores como infarto de miocardio, accidente cerebrovascular y muerte. Si bien se han descripto en detalle ciertas complicaciones hemorrágicas, renales, hepáticas y respiratorias por el uso del ticagrelor, otros efectos adversos menos frecuentes de la droga no han sido adecuadamente escla recidos. Presentamos el caso de un paciente con un síndrome de respuesta inflamatoria sistémica secundario al uso de ticagrelor.
Abstract Ticagrelor is anantiplatelet agent which acts through reversible binding to the P2Y12 adenosine-diphosphate recep tors. In acute coronary syndromes it has been shown to reduce the risk of major cardiovascular events such as myocardial infarction, stroke and death. Although some hemorrhagic, kidney, liver and respiratory complications have been described in detail with the use of ticagrelor, other less frequent adverse effects are not so well clari fied. We report the case of a patient with a systemic inflammatory response syndrome secondary to the use of ticagrelor.

ABSTRACT Kounis syndrome is defined as the coincidental occurrence of allergic reaction and acute coronary syndrome secondary to vasospasm. Anti-inflammatory drugs are included as one of the multiple causes. Current data available about this syndrome come from case reports. We present the case of a patient who suffered Kounis syndrome with cardiogenic shock and asystole after intravenous infusion of Metamizole, and in which no lesions were observed in coronariography.
RESUMO A síndrome de Kounis é definida como a ocorrência concomitante de reação alérgica e síndrome coronariana aguda secundária ao vasoespasmo. Os medicamentos anti-inflamatórios estão incluídos como uma das múltiplas causas. Os dados atuais disponíveis sobre essa síndrome são provenientes de relatos de caso. Relatamos o caso de um paciente que apresentou síndrome de Kounis com choque cardiogênico e assistolia após infusão intravenosa de metamizol e no qual não foram observadas lesões na coronariografia.
