Coronary Artery Disease Management Using Multislice Computed Tomography and Magnetic Resonance Imaging (CAD-Man)
March 11, 2021 updated by: Marc Dewey, Charite University, Berlin, Germany
The primary objective of this study is to analyze the clinical value of a therapeutic management strategy based on the results of coronary CT angiography and functional MRI.
The clinical value of CT and MRI will be analyzed in patients with suspected coronary artery disease.

Complications
Time Frame: during or up to 2 days after procedures
|
Death, stroke, and myocardial infarction and moderate to severe groin hematoma, groin pain, infections, allergies, thromboses, and arteriovenous fistula or other complications (if prolonging the in-hospital stay significantly by at least 24 hours).

Secondary Outcome Measures

Measure Description |
Time Frame |

Hard Cardiovascular Events
Time Frame: Follow-up 3 (36-60 Months)
|
Composite endpoint: The most important secondary outcome will be hard cardiovascular events at final follow-up (3 years).
These hard events include: cardiac and noncardiac death (death from any cause), stroke, and myocardial infarction.
These hard events are considered as major adverse cardiovascular events.

|
To compare contrast-induced nephropathy (CIN) defined as increase in creatinine by 25% or 0.5 mg/dl from baseline at the measurements obtained 18 to 24 and/or 46 to 50 hours after the initial procedures as part of standard safety parameters performed at our institution.
In addition, CIN will also be assessed during the follow-ups.

|
Comparison of Patient Preference
Time Frame: 24 hours after last procedure related to computed tomography or conventional coronary angiography
|
To analyze patient preference and satisfaction with the therapeutic management strategies with a focus on the comfort during the imaging tests.
|
24 hours after last procedure related to computed tomography or conventional coronary angiography
|
Comparison of the Amount of Contrast Agent
Time Frame: 10 minutes after the examinations.
|

|
10 minutes after the examinations.
|
Comparison of the Amount of Radiation Exposure
Time Frame: Comparison of the amount of radiation exposure
|

|
Comparison of the amount of radiation exposure
|
Analysis of Image Quality
Time Frame: Up to 24 hours after the end of computed tomography
|
To analyze which image quality in multislice computed coronary angiography would be required to directly reliably triage patients to coronary artery bypass grafting.

Up to 24 hours after the end of computed tomography
|
Analysis of Correlation and Agreement About the Stenosis Diameter Between Multislice Computed Coronary Angiography and Conventional Coronary Angiography
Time Frame: Up to 24 hours after the end of computed tomography
|

|
Up to 24 hours after the end of computed tomography
|
Comparison of Biological Effects of Radiation Exposure
Time Frame: Z1) before exam, (Z2) 60 min after end of exam, (Z3) 18-24h after exam
|
To compare the biological effects of radiation exposure of ionizing radiation, measured by DNA double-strand breaks in lymphocytes, of CT and conventional coronary angiography themselves and in the two randomization groups (approval by ethics board for this substudy with start of first patient analyzed on September, 15, 2009).
Blood samples are taken for double-strand break analysis.
