Tele-Electrocardiography in Emergency Cardiac Care

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.

About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • All individuals in Santa Cruz County in California who call 911 with symptoms of acute coronary syndrome (chest pain, shortness of breath, anginal equivalent).

Exclusion criteria

  • Those who don't meet the above inclusion criteria.

Treatment and study plan

Electrocardiogram (ECG) Intervention

Device

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

Other

ECG in the ED as part of routine clinical practice.

Primary outcomes

  1. 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

  2. Hospital Time to Treatment for Patients With ST-elevation Myocardial Infarction (STEMI)

    Time frame: Day 1

    Mean door-to-balloon time

Secondary outcomes

  1. Rehospitalization and Mortality

    Time frame: 4 years
