What the trial is, and whether it could suit you
Yearly, 180 000 patients in the Netherlands are referred to a cardiologist with symptoms suspected of coronary artery disease (CAD). To assess this, multiple diagnostic tests are available. Non-invasive imaging tests, such as coronary CT-scan, are safe, relatively cheap and can effectively rule-out CAD. However, when CAD is present, coronary CT-scan cannot assess the restriction in blood flow caused by the stenosis. Cardiac angiography with invasive blood flow measurements is required to assess this restriction in blood flow. This is an invasive test, more expensive than CT and it is accompanied by certain risks.
Most patients in whom CAD is present do not need treatment, and would therefore benefit from non-invasive diagnostic tests. To reduce the number of unnecessary cardiac angiography with flow measurements, new imaging techniques have been developed. These techniques use CT- or an

* The subject has had ≥64 multidetector row coronary CTA or will undergo coronary CTA as part of usual care deemed by the treating physician with ≥64 multidetector row coronary CTA.
Exclusion Criteria:
* The subject is suffering from unstable angina pectoris.
* The subject is suffering from decompensated congestive cardiac failure.
* The subject is suffering from a known non-ischemic cardiomyopathy.
* The subject has a history of PCI or CABG.
* The subject has had pacemaker or internal defibrillator leads implanted.
* The subject has a prosthetic heart valve.
* There is a severe language barrier.

* Clinical condition prohibiting subsequent interventional therapy as indicated by the results of the imaging procedures.
* The subject is or might be pregnant.
* The subject does not comply or is not able to comply to the imaging guidelines for the performance and acquisition of CCTA by the Society of Cardiac Computed Tomography (SCCT), including:
* The subject is suffering from a cardiac rhythm other than sinus rhythm.
* The subject is morbidly obese (Body Mass Index (BMI) \> 40).
* The subject is not able to sustain a breath-hold for 25 seconds.
