Comparison of the Use of an Outpatient/Mobile MRI Procedure With an Inpatient MRI Procedure in Adult Patients With Known or Suspected Coronary Artery Disease (CAD)
Comparison of the Use of an Outpatient/Mobile MRI Procedure With an Inpatient MRI Procedure in Adult Patients With Known or Suspected Coronary Heart Disease in a Randomized Open-label Study
Coronary artery disease (CAD) is the clinically relevant manifestation of atherosclerosis affecting the coronary arteries. CAD is associated with an increased risk of morbidity and mortality and typically presents as angina pectoris or dyspnea. Non-invasive imaging techniques are recommended for the diagnosis of CAD. Of particular importance is stress perfusion cardiac magnetic resonance imaging (CMR), which is distinguished from other recommended diagnostic modalities by its high diagnostic accuracy and the absence of exposure of patients and healthcare professionals to ionizing radiation. Consequently, stress perfusion CMR has been assigned a Class I recommendation in international cardiology guidelines.
The aim of this study is to demonstrate the feasibility of transferring the clinical routine workflow for the diagnostic evaluation of patients with suspected coronary artery disease (CAD) from stationary, specialized centers to mobile MRI units.
This will be demonstrated by comparing two groups. In one group, stress CMR examinations will be performed using mobile MRI units, while in the other group, examinations will be conducted in stationary imaging facilities. Participants will be randomly assigned to one of the two groups.

Descrizione dettagliata
The diagnostic examinations conducted as part of this study will be performed using stress perfusion cardiac magnetic resonance imaging (CMR) with the pharmacologically active agent regadenoson and the contrast agent gadobutrol. A total of 250 patients with a clinical suspicion of hemodynamically significant coronary artery disease (CAD) will undergo stress perfusion CMR using the pharmacologically active vasodilator regadenoson and the contrast agent gadobutrol. Examinations will be performed in either mobile or stationary MRI units. By introducing stress CMR as a mobile diagnostic service, state-of-the-art, highly accurate diagnostic imaging can also be made available in rural areas. This will enable timely diagnostic examinations close to patients' homes, both for patients with abnormal findings and suspected coronary artery disease and for further diagnostic evaluation of patients with already established CAD. Mobile stress CMR diagnostics will provide the treating specialist with additional information to support clinical decision-making regarding the timely initiation of targeted treatment in the cardiac catheterization laboratory, potentially having a positive impact on subsequent treatment and prognosis.
The study aims to achieve the following objectives:
To demonstrate the feasibility of easily performing stress perfusion CMR in a mobile setting using a short, patient- and user-friendly MRI protocol that is identical to the protocol established in clinical routine practice and recommended by professional societies.
Our hypothesis is that there are no differences in the performance of stress CMR examinations in a mobile setting compared with a stationary setting. The primary endpoints are the proportion of successfully completed and evaluable stress CMR examinations with at least adequate image quality.

Mobile Setting Group
Adult patients with suspected coronary artery disease will undergo a clinical indicated stress CMR examination in a mobile MRI unit using stress agent Regadenoson and contrast agent gadobutrol. Stress cardiac examination will be performed In accordance with the protocol established in clinical routine practice and consistent with the MRI examinations performed in the stationary setting group. |

Proportion of unsuccessful or non-evaluable stress CMR examinations
Lasso di tempo: at baseline
|
The primary endpoint is the proportion of unsuccessful or non-evaluable stress CMR examinations (e.g., due to adverse events or insufficient image quality) under an identical examination protocol. In the stationary setting, this proportion is approximately 3%. It is assumed that the proportion will also be 3% in the mobile setting, with mobile stress CMR being considered non-inferior provided that the proportion of unsuccessful or non-evaluable stress CMR examinations does not exceed 10%. Based on these assumptions, a non-inferiority test with a one-sided significance level of 2.5% will have 80% power if 94 patients are enrolled in each study arm. |
