Abstract
We report an unusual case of a male patient with vasospastic angina in whom the pattern of coronary artery spasm changed after coronary stenting. The patient was admitted to our hospital with an acute coronary syndrome. Coronary angiography revealed an intermediate grade stenosis in the right coronary artery, and focal coronary spasm was provoked by intracoronary acetylcholine. A diagnosis of vasospastic angina was made, and the patient was followed medically. He subsequently was readmitted with refractory vasospastic angina and underwent coronary stenting. He was pain-free after stent implantation. Repeat angiography 6 months later showed no restenosis in the stented segment; however, coronary spasm was provoked in all areas except the stented segment by intracoronary acetylcholine injection.
