Brief Summary:
This study aims to investigate the effect of early CTCA in patients with suspected or confirmed Acute Coronary Syndrome (ACS) presenting to the Emergency Department (ED) or Medical Assessment Unit (MAU), upon interventions, event rates and health care costs in a pragmatic clinical trial and economic evaluation up to 1 year after the trial intervention. The primary objective will be to investigate the effect of the intervention on the proportion of patients with all-cause death or recurrent non-fatal type 1 or type 4b myocardial infarction (MI) at one year.

Estimated Study Completion Date : December 2020

No Intervention: Standard Care
Standard care only

Primary Outcome Measures :
  1. The primary end-point will be all-cause death or recurrent non-fatal type type 1 and 4b myocardial infarction at one year, measured as time to first such event. [ Time Frame: 1 year ]
    Myocardial infarction will be defined according to the most recent Universal Definition [Thygesen K, 2012] and will be adjudicated by two independent cardiologists blinded to the intervention and will be adjudicated by two independent cardiologists blinded to the intervention.

Secondary Outcome Measures :
  1. Hospital length of stay [ Time Frame: 1 year ]
  2. Coronary care length of stay [ Time Frame: 1 year ]
  3. Proportion of patients receiving invasive coronary angiography during index hospitalisation [ Time Frame: 1 year ]
  4. Proportion of patients receiving coronary revascularisation during index hospitalisation [ Time Frame: 1 year ]
  5. Proportion of patients receiving subsequent unplanned coronary revascularisation after index hospitalisation within 12 months [ Time Frame: 1 year ]
  6. Proportion of patients in CTCA arm receiving invasive coronary angiography despite <50% stenosis on CTCA [ Time Frame: 1 year ]
  7. Proportion of patients assigned to CTCA with normal or mild non-obstructive disease [ Time Frame: 1 year ]
  8. Proportion of patients prescribed ACS therapies and/or discharged on secondary prevention treatment during index hospitalisation [ Time Frame: 1 year ]
  9. Proportion of patients discharged on prevention treatment or have alteration in dosage of prevention treatment during index hospitalisation [ Time Frame: 1 year ]
  10. Representation or rehospitalisation with suspected ACS/recurrent chest pain within 12 months [ Time Frame: 1 year ]
  11. Patient symptoms (up to 12 months) ROSE Questionnaire [ Time Frame: 1 year ]
    Patient symptoms measured by ROSE questionnaire

  12. Patient quality of life (up to 12 months) EQ-5D-5L questionnaire [ Time Frame: 1 year ]
    Quality of life measured by EQ-5D-5L questionnaire

  13. NHS resource utilisation [ Time Frame: 1 year ]
  14. Patient satisfaction with care questionnaire [ Time Frame: 1 year ]
    Participant questionnaire (11 questions) asking their viewpoint on the care they received during their baseline admission.

  15. Clinician certainty of presenting diagnosis after CTCA [ Time Frame: 1 year ]
  16. Proportion of patients with allergy/anaphylaxis/acute kidney injury [ Time Frame: 1 year ]
    Safety assessment

  17. Proportion of patients with alternative diagnoses that relate to a presentation on CTCA e.g. aortic dissection or incidental but potentially concerning e.g. malignancy or pulmonary embolus [ Time Frame: 1 year ]
    Safety assessment

  18. Proportion of patients with incidental finding but potentially concerning on CTCA e.g. malignancy or pulmonary nodules [ Time Frame: 1 year ]
  19. Total average radiation exposure from CTCA in the intervention arm during index hospitalisation [ Time Frame: 1 year ]
    Safety assessment

  20. Cost effectiveness [ Time Frame: 1 year ]
    Estimated in terms of the lifetime incremental cost per quality-adjusted life year (QALY) gained.

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No


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).


  • 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.
  • 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).
  • 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.
  • Previous recruitment to the trial;
  • Known pregnancy or currently breast feeding;
  • Inability to consent;
  • Further investigation for ACS would not in the patient's interest, due to limited life expectancy, quality of life or functional status;
  • Prisoners
