Computed Tomography Coronary Angiogram (CTCA) Versus Traditional Care in Emergency Department Assessment of Potential Acute Coronary Syndromes (ACS)

Coronary Artery Disease Clinical Trial

Official title:
Randomized Controlled Study of a Rapid "Rule Out" Strategy Using Computed Tomography Coronary Angiogram (CTCA) Versus Traditional Care for Low- to Intermediate-Risk Emergency Department (ED) Patients With Potential Acute Coronary Syndromes (ACS)

Status Completed

Clinical Trial 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.

Clinical Trial Description

In this study, participants with potential ACS will be randomized to traditional "rule out" care (Group A) or to traditional care plus CT coronary angiography (Group B) in a ratio of 1:2 traditional versus traditional plus CT coronary angiography. In Group A, all management and disposition decisions will be made by the healthcare providers caring for the participant. Participants will be admitted to hospital, admitted to cardiac diagnostic unit, or discharged to home. Diagnostic testing and treatment will be decided by the team caring for the participant. Follow up will comprise telephone interviews after 30 days and 1 year from triage/presentation. In Group B, participants will receive initial cardiac troponin and creatinine blood tests. Upon return of normal laboratory values, the participants will receive a CT coronary angiography an estimated 90 minutes after the initial values assessment or as soon as the CT scanner is available. Participants with negative test results will be discharged; follow up will comprise telephone interviews after 30 days and 1 year from triage/presentation. Participants with positive test results will be admitted to the hospital for further management dictated by the admitting team. ;
