Spontaneous Coronary Artery Spasm During Coronary Angiography In A Patient With Exercise-Induced St Segment Elevation

We describe a patient with a history of early morning chest pain who developed ST segment elevation during a treadmill exercise test. Severe coronary artery stenosis was identified initially and was relieved after intracoronary administration of nitroglycerin. A history of vasospastic angina in this patient facilitated prompt diagnosis.
