These scenarios depict only a few diagnostic cardiovascular challenges encountered daily by the emergency physician. The mostappropriate diagnostic and therapeutic approach to the patient in these and other cardiovascular presentations is constantly changing as research continues to improve emergency cardiovascular care. Thepatient with acute coronary syndrome (ACS) represents numerous challenges to the emergency physician.
