Inclusion Criteria:
- 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

of current or pre-existing cardiovascular and lung disease and absence of medication
with cardiovascular effects)
Exclusion Criteria:

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

Health Condition(s) or Problem(s) studied
|
Coronary Artery Disease
|
Primary Outcome(s)
|
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.
[Time Frame: OS-CMR with breathing maneuvers will last about 5-10 minutes]
|
Secondary Outcome(s)
|
Clinical feasibility of OS-CMR with breathing maneuvers
[Time Frame: 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
[Time Frame: OS-CMR with breathing maneuvers will last about 5-10 minutes]
|
Relationship between OS-SI changes during OS-CMR with breathing-maneuvers and Fractional Flow Reserve (FFR) measurements in CAD patients
[Time Frame: OS-CMR with breathing maneuvers will last about 5-10 minutes]
|
Presence of side effects during OS-CMR with breathing maneuvers
[Time Frame: OS-CMR with breathing maneuvers will last about 5-10 minutes]
