AB Of  ED  patients  with  undifferentiated  chest  pain,  7%  will  have  ECG  findings  consistent  with  acute  ischemia  or  infarction,  and  6%  to  10%  of  those  in  whom  cardiac  markers  are  ordered  will  have  initially  positive  results.1  The  remaining  patients  who  do  not  have  diagnostic  ECG  changes  or  initially  positive  cardiac  marker  results  have  low-probability  or  possible  acute  coronary  syndrome  (ACS;  either  infarction  or  ischemia  including  unstable  angina  pectoris).  The  evaluation  of  those  with  possible  ACS  costs  approximately  $10  billion  to  $12  billion  each  year  in  the  United  States.2
