Gadobutrol/Gadavist-enhanced cardiac magnetic resonance imaging (CMRI) to detect Coronary Artery Disease (CAD)

Trial purpose

Participants being evaluated for suspected or known Coronary artery Disease (CAD) based on signs and/or symptoms, will be invited to participate in the study. The duration for a participant in the study may range from 2 days to 4-6 weeks. One to four visits to the study doctor will be required.
This study will investigate the diagnostic results of gadobutrol-enhanced Cardiac Magnetic Resonance Imaging (CMRI) images regarding the detection (sensitivity) and exclusion (specificity) of coronary artery disease utilizing a uniform image acquisition software. The CMR images will be tested either against the results from routine clinical Coronary Angiography (CA) or those from Computed Tomography Angiography (CTA), which is used as the standard of reference. The CA/CTA may have been performed up to 4 weeks prior to enrollment or be scheduled up to 4/6 weeks after the study.
CMRI and CA/CTA images will be collected for an independent image review (blinded read).

Primary Outcome

  • Presence of a Myocardial Perfusion Defect Indicating Significant CAD per Participant on Gadobutrol-enhanced CMRI (Based on RPS) – Primary Analysis of Sensitivity Based on Blinded Readers' Assessment
    Blinded readers evaluated 6 myocardial regions based on regional perfusion score (RPS), 0=normal; 1=abnormal, reversible perfusion defect (stress); 2=abnormal, mixed perfusion defect (reversible and fixed/permanent components); 3=abnormal, fixed/permanent perfusion defect/scar (stress and rest)]. A myocardial region a perfusion defect in case of a RPS of >=1 and was rated to have normal perfusion in case of a RPS of 0. Significant CAD was defined as quantitative coronary angiography (QCA) stenosis of >=50% for primary analysis, and was determined based on the presence of a myocardial perfusion defect on gadobutrol-enhanced cardiac magnetic resonance imaging (CMRI) verified by standard of reference (SoR). Sensitivity= true positive/ (true positive + false negative).
