Description of intervention(s) / exposure
Observational. Prospective recruitment of patients identified by our protocol as non- high risk are followed up at thirty days from their index presentation to the Emergency Department (ED).
Patients are eligible for the protocol if they have chest pain, a non-diagnostic electro-cardio-gram (ECG) and no immediate non-cardiac cause.
Based on the clinical presentation a Senior ED Physician assesses the pre-test risk for a thirty day event. High sensitivity cardiac troponin T is taken as close to arrival time as possible with a second troponin at two hours, based on serial clinical observation ECG and High sensitivity troponin testing a post test judgement of high or non-high risk is made by a senior ED physician. An initial troponin T of <14ngm/l with a two hour delta of 5 or less is non-high risk, an initial troponin of between 14 and 52ngm/l with a delta of <5ngm/l equals non-high risk a value >52ngm/l equals high risk. Senior physician gestalt trumps the protocol.

Not applicable
Comparator / control treatment
Rule-out rule in high risk within six hours ED length of stay. Rule out requires a non diagnostic ECG and early SMO pre test probablitiy for ACS 30 day event. HS trop TR is taken at time zero and again at two hours if required. Basline tropnin < 14ng/l with delta of <5 at two hours is rule out. Mid range troponin 14-53 ng/l and delta <5 was rule out. SMO gestalt for rule in trumps the protocol.

Uncontrolled

Outcomes
Primary outcome [1] 291729 0
Combined death acute myocardial infarction (AMI )at thirty days.
Combined record review and follow -up structured telephone interview
Timepoint [1] 291729 0
Thirty days following index ED presentation
Secondary outcome [1] 307362 0
Senior ED physician pre-test and post test probability for adverse outcome. pre test probablity is obtained prior to knowledge of HS troponin result. Post test probabilty is designated by the ADP where senior ED physician determines high or non high risk for 30 day ACS/death
Timepoint [1] 307362 0
30 days following index presentation
Secondary outcome [2] 307367 0
ED length of stay
Timepoint [2] 307367 0
ED length of stay is measured as triage to discharge from ED time. Bench marked against six hour ED length of stay.
