Reducing Acute Coronary Syndrome Time in the Emergency Department for Patients with Non-Traumatic Chest Pain
Scientific title
In patients presenting to an Emergency department with non-traumatic chest pain, does the introduction of a new multimatker strategy compared with the current standard practice of an 8 hour troponin, safely reduce the length of time spent in the emergency department?

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention is the introduction of an accelerated multimarker based chest pain protocol, performing serum Myoglobin, Creatine kinase -MB and Troponin-I on arrival and either 2 hours later or at least 4 hours after the onset of the patients maximal pain, whichever is later

Comparator / control treatment
We will compare retrospectively with patients managed using the standard 8 hour troponin recommended by current Australian national guidelines prior to the introduction of the protocol from November 2009 till December 2009

Outcomes
Primary outcome [1] 257494 0
Major adverse cardiovascular events (MACE) - a composite end point of any of the following: Myocardial infarction, Cardiac death, cardiac arrest, major cardiac revascularization, cardiogenic shock, new ventricular arrhythmia requiring treatment, 2nd or 3rd degree heart block requiring intervention.
These events will be assessed by telephone followup of both the patient and the patient's General Practitioner (GP) as well as collection of data such as Electrocardiograms, cardiological investigations from their medical notes as well as a search through Western Australian Death registry for any patients lost to follow up, at the end of the trial.
Outcomes will be adjudicated by a consultant cardiologist and a consultant emergency physician not involved in data collection. Any disagreements will be resolved by another consultant cardiologist.

Secondary outcome [1] 262689 0

Study design
Purpose of the study
Diagnosis
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The intervention (ie: the multimarker pathway) is in widespread use internationally and is ranked as having the same level of evidence as our current practice by the current American College of Emergency Physicians (ACEP) guidelines. All patients presenting with non-traumatic chest pain will be managed with our new multimarker stategy. Our study is different in that it is using the latest generation of laboratory based super-sensitive troponin assays. Patients will be identified at triage and photocopies of their notes will be placed in the study form collection box by the doctor on completion.
