Key result
Eosinophilia links to severe coronary artery vasospasm often refractory to traditional therapies.
Why the study?
Coronary vasospasm in patients with eosinophilia presents with severe manifestations and is often refractory to traditional therapies, but few cases are reported.
Case Report (n=3)
Highlights the severe and refractory nature of coronary vasospasm in patients with coexisting eosinophilia.
Eosinophilia may mark severe, refractory coronary vasospasm; extends sparse reports but remains hypothesis-generating.
Coronary vasospasm is a relatively well-documented cause for ischemia and myocardial infarction in patients with nonobstructive coronary artery disease. Patients with coexisting eosinophilia present with severe manifestations and are often refractory to traditional therapies. There are few reported cases in the literature. We describe 3 cases occurring within 10 months. (Level of Difficulty: Intermediate.)

Backhouse et al. (2023) conducted a case report in Coronary artery vasospasm with eosinophilia (n=3). Eosinophilia was evaluated. Three cases of coronary artery vasospasm in patients with coexisting eosinophilia were described, highlighting a severe manifestation often refractory to traditional therapies.
