Selective ergonovine-induced coronary artery spasm and ST-segment alternans after blunt thoracic trauma.
A 24-year-old man was found to have angiographically normal coronary arteries shortly after suffering blunt thoracic trauma. Selective ergonovine administration into the left coronary artery induced total occlusion of the left anterior descending branch and electrical alternans of the ST-segment. This case demonstrates coronary artery spasm as a possible mechanism of coronary occlusion after blunt thoracic trauma.
