ADAPT and ASPECT (ACTRN12609000283279) are parallel studies both of which are part of the Austalia New Zealand Acute Chest Pain (ANZACP) registry. Both studies began at the same time Sept. 2007 but ADAPT continue for longer until February 2011. The studies used a common participant recruitment and outcomes determination process but index test biomarker analysis was performed completely separately.

Description of intervention(s) / exposure
A risk assessment will be made using the TIMI score , ECG and measurements of central lab Troponin I taken from people who present with probable ischaemic chest pain to the Emergency Department. A sample is tested on arrival and again 2 hours later.
ADAPT and ASPECT both started in Christchurch in November 2007 final recruitment for ASPECT occured in Singapore in July 2010; recruitment for ADAPT finished in Brisbane February 2011

Outcomes
Primary outcome [1]

0
To prospectively validate an accelerated chest pain algorithm involving core lab Troponin I measurements over a 2 hour time period from presentation to the Emergency Department (ED) in patients with possible Acute Coronary Syndrome (ACS).
Occurence of patient outcomes at 30 days and 1 year post presentation will be determined using patient follow-up at 45 days, 6 months and 1 year post presentation.

Summary
Brief summary
This is a prospective observational study of the diagnostic utility of an accelerated diagnostic protocol using a central laboratory Troponin I in people presenting to the Emergency Deprtment with chest pain of probable caridac origin. A blood sample will be taken and tested on arrival and again at 2 hours. Participants will undergo risk evaluation by a means of a set series of questions. Patients will be followed-up to determine outcomes at 30 days and 1 year after presentation
