Show: Emergency Medical Minute
Author: Don Stader, M.D.
Educational Pearls
- While we usually associate the coronary vasculature with STEMIs, there are other pathologies that can affect the heart's blood supply.
- Kounis syndrome: an allergic vasospasm of the coronary arteries. This can happen post anaphylaxis or be caused by a stent allergy. It is best treated with aggressive management of the allergic reaction.
- Kawasaki disease: An autoimmune condition that presents in kids as conjunctivitis, lymphadenopathy, hand/foot swelling, rash, and fever. It can also cause coronary aneurysms, which can rupture and be rapidly fatal.
- Prinzmetal angina: Caused by coronary vasospasm. Presents with transient chest pain at rest. Treat with CCBs.
- Cocaine: Causes coronary vasospasm. Cocaine-induced vasospasm is best treated with BZDs.
- Coronary artery dissection: increased risk in pregnant women and those with connective tissue disorders.
