Hypersensitivity to aspirin and urgent percutaneous coronary intervention: A therapeutic challenge

Abstract

Hypersensitivity reactions to nonsteroidal anti-inflammatory drugs are common and five types of reactions have been defined. The prevalence of such reactions in patients with myocardial infarction is unclear, and so antiplatelet therapy in this population is a challenge. Various desensitization protocols have been developed but there are no specific guidelines for their use. The authors present the case of a patient with acute coronary syndrome and aspirin hypersensitivity referred for urgent coronary angiography. Aspirin desensitization therapy is safe and successful in many patients, but more randomized trials are needed to confirm its benefits in coronary artery disease patients.
