Study information

Scientific title

Clinical evaluation of MAgnetic Resonance imaging in Coronary heart disease



Study hypothesis

Approximately 2.5 million people in the UK suffer from the symptoms of CHD. Currently patients with CHD undergo a number of tests, including angiography, which carries a small but significant risk. It is anticipated that the new test of Cardiac Magnetic Resonance Imaging (CMRI) will be more reliable in identifying those patients who would benefit from a bypass or angioplasty than current non-invasive tests.

This research programme will include the first large-scale prospective evaluation of a validated comprehensive CMRI imaging protocol compared to the standard non-invasive tests Exercise Treadmill Testing (ETT) and Single Photon Emission Computed Tomography (SPECT) for the diagnosis of suspected Coronary Heart Disease (CHD) with x-ray coronary angiography as the reference standard. Patient follow up will provide much needed prognostic data for CMRI, and a health economic evaluation and assessment of patient preference will be performed for the different investigation strategies.

Coronary heart disease


Comparing non-invasive techniques for diagnosing coronary artery disease (ETT, SPECT and CMR) against invasive angiography. Patients who agree to take part in the study will initially undergo three investigations: ETT and then in random order, cardiac Magnetic Resonance Imaging (MRI) and SPECT imaging. After all three tests have been completed, all patients will undergo x-ray angiography.

Intervention type



Not Specified

Drug names

Primary outcome measure

The diagnostic performance of MRI to detect significant CHD on x-ray angiography

Secondary outcome measures

1. The diagnostic performance of current standard clinical investigations of ETT and SPECT
2. The cost effectiveness of CMRI in a diagnostic strategy for the systematic investigation of patients with suspected CHD
3. Patient's preference of the different strategies for the investigation of suspected CHD
