A recent study from the Royal Brisbane and Women’s Hospital, published in the MJA
reported that three-quarters of patients presenting to EDs with chest pain could be rapidly assessed using risk stratification tools, early troponin testing and selective objective testing. The
Improved Assessment of Chest pain Trial (IMPACT) included 1366 patients who presented over 3 years with symptoms of suspected acute coronary syndrome (ACS). The researchers found an
overall 30-day ACS rate of 6.6%, none of which occurred in the low risk group. There were 14 ACS cases (1.8%) in intermediate risk patients.
