Abstract
An ST elevation myocardial infarction is life-threatening and requires urgent management. Before coronary intervention, preoperative loading a P2Y12 receptor antagonist is warranted. We present a case in which urgent coronary angiography was performed after given loading dose of Aspirin and Ticagrelor. Two and a half hours after loading Ticagrelor, patient developed hypotension with swollen face and diffuse rash on the trunk. Consideration of the anaphylactic shock, a steroid bolus and an inotropic infusion were administered and patient became hemodynamically stable. The allergic manifestations disappeared a few hours later, Ticagrelor was changed to Clopidogrel to avoid the severe allergic reaction.
