Case report reveals left main coronary artery syndrome with myocardial bridging, indicating the need for awareness of allergic myocardial ischemia.
Bee stings are a frequent environmental exposure, yet myocardial infarction (MI) following a sting is exceedingly rare. We report a patient who developed electrocardiographic features consistent with a left main coronary artery (LMCA) infarction following a bee sting. Coronary angiography revealed no LMCA obstruction but demonstrated a mid–left anterior descending (LAD) myocardial bridging segment. This case exemplifies the rare coexistence of Kounis syndrome (allergic acute coronary syndrome/allergic angina) and myocardial bridging, resulting in transient ischemia mimicking left main occlusion. Awareness of this interplay is crucial for accurate diagnosis and appropriate management of allergic myocardial ischemia.
