Brief Summary
The purpose of this study is to see whether individuals who access the "911" emergency medical system with a heart attack or severe chest pain will receive more timely hospital treatment and better outcomes if hospital clinicians are provided with earlier and more complete electrocardiography (ECG) information.

Outcome Measures
Primary Outcomes (2)
Hospital Time to Treatment for Patients With Unstable Angina/Non-STEMI
Time from ED arrival to first drug was determined as recommended by American College of Cardiology/American Heart Association 2007 guidelines for management of patients with unstable angina/non-STEMI
Day 1
Hospital Time to Treatment for Patients With ST-elevation Myocardial Infarction (STEMI)
Mean door-to-balloon time
Day 1
Secondary Outcomes (1)
Rehospitalization and Mortality
4 years
Study Arms (2)
Electrocardiogram (ECG) Intervention
EXPERIMENTALPatients randomized to the experimental group had their ECGs printed out in the target ED with an audible voice alarm. Print-out of the pre-hospital ECG in the target ED was the intervention.
Routine Clinical Practice
OTHERControl patients had an ECG conducted after hospital arrival, as was the standard of care in the county.
Interventions
Pre-hospital electrocardiographic (ECG) monitoring with special software to detect myocardial ischemia and to automatically transmit an ECG to the destination hospital emergency department with a voice alarm announcing "Incoming ECG from the field" and print out in the ED.
ECG in the ED as part of routine clinical practice.
Eligibility Criteria
You may qualify if:
- All individuals in Santa Cruz County in California who call 911 with symptoms of acute coronary syndrome (chest pain, shortness of breath, anginal equivalent).
