Acetylcholine-induced coronary spasm in the left anterior descending arteryLeft panel: Coronary angiogram demonstrating a normal-appearing left anterior descending (LAD) artery prior to intracoronary acetylcholine administration.

This was associated with retrosternal chest pain rated at 8/10 and a 3 mm ST-segment elevation, both of which resolved promptly after intracoronary nitroglycerin administration.
