Study Summary
This multi-center, randomized, controlled trial conducted in Emergency Departments (ED) compares computed tomography (CT) coronary angiography with the traditional approach (usual care) for low- to intermediate-risk chest pain patients. The primary objective is to estimate the rate of major cardiac events (heart attack or cardiac death) within 30 days in trial participants in Group B who were not found to have significant coronary artery disease by CT coronary angiography. Additional evaluations will comprise health care utilization assessments, including length of hospital stay and re-admissions, cost analysis, and 1-year post-triage/presentation major cardiac event rates.
Primary Outcome
To estimate the rate of major cardiac events (AMI or cardiac death) within 30 days of discharge from Emergency Department (ED) - patient follow-up included telephone interviews 30 days and 1 year after triage/presentation. Participants in Group B who were found not to have stenosis of the main or first order coronary branches greater than or equal to 50% by CT coronary angiography were considered negative and considered discharged if they were not designated to receive an inpatient bed or forma
