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:

- 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

Age minimum: 18 Years
Age maximum: N/A
Gender: All
Health Condition(s) or Problem(s) studied
Coronary Artery Disease
Intervention(s)
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]
