RT Journal Article SR Electronic T1 Lesson of the month 1: Beware the atypical presentation: eosinophilic granulomatosis with polyangiitis presenting as acute coronary syndrome JF Clinical Medicine JO Clin Med FD Royal College of Physicians SP 180 OP 182 DO 10.7861/clinmedicine.17-2-180 VO 17 IS 2 A1 Juergen Schiefermueller A1 Bashir Alaour A1 Alison Calver A1 Nick Curzen YR 2017 UL http://www.rcpjournals.org/content/17/2/180.abstract AB We describe the case of a 45-year-old woman presenting with troponin positive cardiac-sounding chest pain. An initial emergency angiogram demonstrated two vessel coronary disease, including a distal right coronary artery occlusion. No percutaneous coronary intervention was performed and the patient was treated medically. At re-presentation with further pain a few days later, coronary angiography demonstrated no significant coronary lesions. After consideration of other multisystem symptoms and raised eosinophil count, the patient was diagnosed with eosinophilic granulomatosis with polyangiitis (formerly known as Churg-Strauss syndrome) presenting with coronary arteritis. This case should remind physicians to be vigilant and to consider non-atherosclerotic causes of acute coronary syndrome presentation, which should not always result in a stent.
