Brief Summary
Recent advances in technology have resulted in the development of scanners that can image the heart blood vessels within 10 to 20 minutes but without the need for admission to hospital or insertion of catheters. Further advances in technology allow the visualisation of both the blood vessels and the supply of blood to the heart muscle. Here we propose to assess the latest and most powerful computed tomography scanner and compare it to magnetic resonance and conventional coronary angiography.

Outcome Measures
Primary Outcomes (1)
Myocardial perfusion defects defined qualitatively by trained observers and quantitatively by computer software
The primary outcome measure is to establish whether 320-multidetector computed tomography can identify myocardial perfusion defects as compared to the gold standards of 3Tesla magnetic resonance imaging and fractional flow reserve measured during invasive coronary angiography.
1 month
Secondary Outcomes (4)
Identification of regional wall motion abnormalities qualitatively by trained observers
1 month
Identification of infarction qualitatively by trained observers

Identification of regional wall motion abnormalities quantitatively by computer software

Study Arms (1)
Patients
Patients awaiting invasive coronary angiography
Interventions
Computed tomography will be performed using a 320 multidetector computed tomography scanner and may include coronary calcium score, coronary angiography and imaging of myocardial perfusion, function and viability.
Eligibility Criteria
Patients awaiting invasive coronary angiography
You may qualify if:
- referred for invasive coronary angiography because of suspected coronary heart disease
You may not qualify if:
- inability or unwillingness to undergo computed tomography or magnetic resonance imaging
- renal failure (serum creatinine \>200 micromol/L or estimated glomerular filtration rate \<30 mL/min)
- hepatic failure
- allergy to iodinated contrast or gadolinium
- pregnancy
- contraindication to adenosine infusion
- inability to give informed consent
- inability to perform fractional flow reserve during invasive coronary angiography
