- The primary end-point will be all-cause death or subsequent non-fatal type 1 or type 4b MI 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.

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
INCLUSION 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).
EXCLUSION CRITERIA
-
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
