NCT01634425

Brief Summary

The purpose of this study is to determine if early diagnosis and risk stratification acquired through pre-hospital clinical assessment, 12-lead electrocardiogram and point of care biomarkers will facilitate enhanced triage and treatment in patients with presumed non-ST elevation acute coronary syndromes (NSTEMI).

Outcome Measures

Primary Outcomes (1)

  • Time from first medical contact to final patient disposition.

    An Adjudication Committee will examine the records to determine final diagnosis. Final patient disposition is defined as the time when a plan for patient discharge from the ED or admission to hospital is both established and documented.

    From date of first medical contact until first appropriate therapy given, assessed up to 30 months

Secondary Outcomes (6)

  • Time to administration of appropriate evidence based therapy

    Assessed up to 30 months.

  • Length of hospital stay for patients admitted to hospital

    Assessed up to 30 months

  • In-hospital clinical events (day 7 or discharge) all-cause mortality, cardiogenic shock, heart failure, re-Myocardial infarction

    Assessed up to 30 months

  • 30-day all-cause mortality

    Assessed up to 30 months

  • 30 day all-cause hospitalization or re-hospitalization

    Assessed up to 30 months

  • +1 more secondary outcomes

Other Outcomes (1)

  • Explore the incremental value pre-hospital BNP on primary and secondary endpoints.

    Assessed up to 30 months

Study Arms (2)

Group 1 - no pre-hospital biomarkers

NO INTERVENTION

Standard of Care

Group 2 - pre-hospital biomarkers

EXPERIMENTAL

Troponin and BNP measured on a POC meter in the ambulance on the way to the hospital.

Device: Alere Triage Meter Pro

Interventions

Troponin and BNP measured on point of care meter.

Also known as: Point of Care Meter
Group 2 - pre-hospital biomarkers

Eligibility Criteria

Age31 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patient that activates pre-hospital Emergency Medical Services (EMS) for symptoms of acute chest discomfort for which acute cardiovascular disease is deemed to be the most probable diagnosis by EMS personnel.
  • Patient is older than 30 years of age
  • Patient is able to give informed consent

You may not qualify if:

  • Patient with documented ST elevation on the initial 12 lead ECG
  • Patient with a prior diagnosis that is compatible with another disease i.e. severe asthma, etc.
  • Patient with Central Nervous System symptoms or syncope
  • Patient with cardiac arrest, ventricular tachycardia or atrial fibrillation with heart rate \> 110 bpm
