Acute Coronary Spasm Following Pelvic Fracture, Bleeding, and Shock in a Trauma Patient

Acta Med Okayama. 2023 Aug;77(4):423-427. doi: 10.18926/AMO/65753.

Abstract

We report a case of a patient with severe pelvic fracture who showed concurrent ST elevation on electrocardiogram. A 70-year-old man incurred an unstable pelvic fracture from a motorcycle accident. On admission, he was hemodynamically unstable, and massive transfusion and noradrenaline were administered immediately. Although ST elevation was present in leads II, III, aVF, V5, and V6, cardiac function was preserved; thus, trans-arterial embolization and external fixation for pelvic fracture were given priority. Four days after the injury, he suffered a cardiac arrest, and coronary angiography revealed that the cause of ST elevation and cardiac arrest was coronary vasospasm. Physicians should be aware that pain-related stress and platelet activation as well as use of noradrenaline in severe trauma cases can induce coronary vasospasm.

Keywords: ST elevation; coronary spasm angina; noradrenaline; severe trauma; treatment strategy.
