Outcome Measures

Primary Outcomes (1)

  • Comparison of myocardial oxygenation signal intensity changes (OS-SI) changes between healthy and post-stenotic myocardium during OS-CMR with breathing-maneuvers in CAD patients.

    Myocardial oxygenation signal intensity changes (OS-SI) changes between healthy and post-stenotic myocardium during OS-CMR with breathing-maneuvers

    OS-CMR with breathing maneuvers will last about 5-10 minutes

Secondary Outcomes (4)

  • Relationship between OS-SI changes during OS-CMR with breathing-maneuvers and Fractional Flow Reserve (FFR) measurements in CAD patients

    OS-CMR with breathing maneuvers will last about 5-10 minutes

  • Relationship between OS-SI changes during OS-CMR with breathing-maneuvers and Quantitative Coronary Angiography (QCA) measurements in CAD patients

    OS-CMR with breathing maneuvers will last about 5-10 minutes

  • Presence of side effects during OS-CMR with breathing maneuvers

    OS-CMR with breathing maneuvers will last about 5-10 minutes

  • Clinical feasibility of OS-CMR with breathing maneuvers

    OS-CMR with breathing maneuvers will last about 5-10 minutes

Study Arms (2)

CAD patients

Consecutive patients scheduled for a coronary angiography on the basis of cardiac symptoms and a test positive for inducible coronary ischemia, who are affected by one-vessel or two-vessel CAD at the time of the OS-CMR with breathing maneuvers (HVBH).

Healthy subjects

Subjects without current or pre-existing cardiovascular and lung disease and absence of medication with cardiovascular effects.

Eligibility Criteria

Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Consecutive patients scheduled for a coronary angiography on the basis of cardiac symptoms and a test positive for inducible coronary ischemia, who show one-vessel or two-vessel CAD at coronary angiography.

You may qualify if:

  • Age \> 18 y
  • Informed consent as documented by signature (Appendix Informed Consent Form)
  • Indication for invasive coronary angiography based on symptoms and a test positive for inducible coronary ischemia
  • One-vessel or two-vessel CAD at coronary angiography (For healthy volunteers: absence of current or pre-existing cardiovascular and lung disease and absence of medication with cardiovascular effects)

You may not qualify if:

  • General MRI contraindications (i.e pacemakers, defibrillating wires, implanted defibrillators, intracranial aneurysm clips, metallic foreign bodies in the eyes, knowledge or suspicion of pregnancy)
  • Acute Coronary Syndrome (ACS) or other acute cardiac injury within 4 weeks
  • Previous myocardial infarction, percutaneous coronary intervention or coronary artery bypass surgery
  • Hemodynamically unstable conditions
  • Significant or uncontrolled arrhythmias
  • Lack of ability to follow commands
  • Vasoactive medication (e.g. nitro or ß blockers) or nutrition with caffeine (coffee, tea, cocoa, chocolate, "energy drink") during the 12 h before the exam
  • Non-ischemic cardiomyopathy
  • Severe Pulmonary Disease
