Tirofiban-induced acute profound thrombocytopenia after primary angioplasty.

Glycoprotein IIb/IIIa inhibitors are used in the acute coronary syndromes and percutaneous coronary intervention as antiplatelet agents. However, these agents induce thrombocytopenia in approximately 1% to 5% of patients, and may lead to bleeding complications. Abciximab is associated with higher incidence of thrombocytopenia than eptifibatide and tirofiban. We describe a case of acute profound thrombocytopenia due to on tirofiban treatment in a patient who underwent primary angioplasty.
