A young woman presents with typical retrosternal burning at rest and slightly elevated troponin levels. There was subtle ST deviation in inferior leads. Coronary angiography showed typical vasospasm at right coronary artery that resolves with nitroglycerin.
Variant angina is a form of unstable angina that usually occurs spontaneously and is characterized by transient ST-segment elevation that resolves spontaneously or with nitroglycerin use usually in the presence of coronary artery disease. Absence of ST deviation is rare in variant angina.
