UK Portfolio Adoption:

The trial is funded by the NIHR Health Technology Assessment Programme. The trial has been adopted onto the NIHR portfolio and therefore is eligible to receive CRN support.

Open parallel group randomised controlled trial of early computed tomography coronary angiography (CTCA) in patients presenting with suspected/confirmed acute coronary syndrome (ACS) to Emergency Departments (ED) and Medical Assessment Units (MAUs).

~30 EDs, acute medical services, radiology and cardiology departments in tertiary/district general NHS hospitals.

Target population:
Patients with suspected or confirmed ACS

Health technologies being assessed:
Early use of ≥64-slice CTCA as part of routine assessment compared to standard care.

Primary Endpoint:
The primary end-point will be all-cause death or recurrent non-fatal type 1 or type 4b MI at one year and time to first such event.

 Eligibility Criteria


Patient ≥18 years with symptoms mandating investigation for suspected or confirmed ACS with at least one of:

  • ECG abnormalities e.g. ST segment depression >0.5 mm;
  • History of ischaemic heart disease (where the clinician assessing patient confirms history based on patient history or available records);
  • Troponin elevation above the 99th centile of the normal reference range or increase in high sensitivity troponin meeting European Society of Cardiology criteria for ‘rule-in’ or myocardial infarction

(NB troponin assays will vary from site to site; local laboratory reference standards will be used).


  1. Signs, symptoms, or investigations supporting high-risk ACS:
    • ST elevation MI;
    • ACS with signs or symptoms of acute heart failure or circulatory shock;
    • Crescendo episodes of typical anginal pain;
    • Marked or dynamic ECG changes e.g. ST depression of >3 mm
    • Clinical team have scheduled early invasive coronary angiography on day of trial eligibility assessment.
  1. Patient inability to undergo CT:
    • Severe renal failure (serum creatinine >250 µmol/L or estimated glomerular filtration rate <30 mL/min);
    • Contrast allergy;
    • Beta blocker intolerance (if no alternative heart rate limiting agent available/suitable) or allergy ;
    • Inability to breath hold;
    • Atrial fibrillation (where mean heart rate is anticipated to be greater than 75 beats per minute after beta blockade).
  1. Patient has had invasive coronary angiography or CTCA within last 2 years and the previous investigation revealed obstructive coronary artery disease, or patient had either investigation within the last 5 years and the result was normal.
  1. Previous recruitment to the trial;
  1. Known pregnancy or currently breast feeding;
  1. Inability to consent;
