Arm Pain After Walking Up a Flight of Stairs

Acute coronary syndrome is a leading cause of mortality and morbidity worldwide, requiring emergency care and admission. Wellens syndrome is a preinfarction state that may not have the classic electrocardiographic findings expected with other forms of acute coronary syndrome or the elevated cardiac enzymes. This lack of typical changes in electrocardiography provides a clinical challenge for diagnosis. The ability to promptly identify and treat this time-sensitive state of potential myocardial infarction and death has a significant prognostic value that cannot be overstated. (c) 2022 Elsevier Inc.
