This study has been completed.

University of California, San Francisco Identifier:
First received: January 2, 2004
Last updated: May 15, 2015

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.

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment

Primary Outcome Measures:
  • Hospital Time to Treatment for Patients With Unstable Angina/Non-STEMI [ Time Frame: Day 1 ]
    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

  • Hospital Time to Treatment for Patients With ST-elevation Myocardial Infarction (STEMI) [ Time Frame: Day 1 ]
    Mean door-to-balloon time

Secondary Outcome Measures:
  • Rehospitalization and Mortality [ Time Frame: 4 years ]

Enrollment: 794
Study Start Date: September 2003
Study Completion Date: June 2009
Primary Completion Date: June 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Electrocardiogram (ECG) Intervention
Patients 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.
Device: Electrocardiogram (ECG) Intervention
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.
Routine Clinical Practice
Control patients had an ECG conducted after hospital arrival, as was the standard of care in the county.
Other: Routine Clinical Practice
ECG in the ED as part of routine clinical practice.

Detailed Description:
This is a Phase III study. Patients will be randomized (like tossing a coin) to 1 of 2 groups: Group 1: Patients will have pre-hospital ECG intervention. Group 2: Patients will have routine emergency heart care. Information will be collected about time symptoms started, clinical management, and other measures. All patients will be contacted by telephone 12 months later and interviewed as to whether they experienced any cardiac symptoms.
