Coronary vasospasm as a cause of angina following interventional recanalization.
Angina following a coronary intervention may be due to vasospasm rather than restenosis. Two cases of angina following a previously successful recanalization are described. In both cases vasospasm was documented as the cause of angina, determined in one case by using an ergonovine provocative test and in the other by using lesion response to nitroglycerine. Rather than another intervention, vasodilator treatment was instituted, with effective symptom amelioration.
