A 29-year-old woman without history of cardiac disease or risk factors sought treatment for sudden onset of chest pain radiating down the back, jaw, and arms, complicated by discomfort in the orthostatic position and severe headache. She had a history of epistaxis since childhood as well as familial history of epistaxis via her mother. BMI was 22 kg/m2, and electrocardiography showed ST segment depression in V1V2 precordial leads and T-wave inversion in inferior leads. Troponin was elevated at 3,700 ng/L (normal, < 34 ng/L), with a peak of 11,115 ng/L.
