Variant angina in chronic kidney disease: a case report of an unusual presentation of cardiac arrest following dialysis

摘要

Variant angina (VA) is described as a relatively benign syndrome of unprovoked chest pain and electrocardiographic (ECG) changes. Chronic kidney disease (CKD) may be associated with this syndrome. However, the incidence of severe manifestations of VA in this patient cohort with kidney disease has not been elucidated. Also, no description has been made of coronary vasospam in relation to dialysis sessions. Our patient, a young female with CKD, had an unusual history of angina following dialysis sessions and she suffered an acute coronary syndrome complicated by cardiac arrest. The diagnosis was made on the basis of her clinical features, dynamic ECG changes, and coronary angiogram findings, and the patient was managed medically. Severe manifestations of VA may occur in chronic kidney disease, and this should be kept in mind by the treating physician. The association of coronary vasospasm with dialysis needs further analysis.
