Widespread ST-segment elevation due to diffuse coronary artery spasm: A case report
Abstract:
Coronary artery spasm (CAS) is considered an important mechanism of acute coronary syndrome but not very common in the clinical setting. We report a case of a 42-year-old woman with chest pain lasting for 4 h due to diffuse CAS, which led to widespread ST-segment elevation in multiple leads of the electrocardiogram and elevated cardiac troponin T. Emergency coronary angiography at admission showed significantly different morphological results from the second angiography during hospitalization, indicating the patient's discomfort was due to CAS rather than stenosis. Our case illustrates that diffuse CAS can cause widespread ST-segment elevation and severe ACS.
