Please assess the completion status of the following clinical trial:

Trial Title: Comparison of Dobutamine and Regadenoson Stress Cardiac Magnetic Resonance (MR)

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: CROSSOVER
- Observational Model: None
- Primary Purpose: DIAGNOSTIC
- Time Perspective: None
- Masking: SINGLE
- Phase: EARLY_PHASE1
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* Men and women aged 40 to 85 years with OBSTRUCTIVE AIRWAY DISEASES (ASTHMA AND COPD) and a forced expiratory volume (FEV1) \> 0.5.~* Patients should have a clinical indication to undergo cardiac stress test with dobutamine.~Exclusion Criteria:~* Those with pacemakers, defibrillators, functioning neural stimulator devices or other implanted electronic devices.~* Ferromagnetic cerebral aneurism clips or other intraorbital and intracranial metal.~* An allergy to Gadolinium or other severe drug allergies.~* Acute myocardial infarction within 3 months.~* Moderate or severe aortic stenosis or other significant valvular disease;~* Claustrophobia.~* High grade (2o or 3o) AV Block.~* Closed angle glaucoma.~* Participants unable to provide informed consent.~* Renal dialysis (subjects with moderate-to-severe renal impairment defined as eGFR \< 60 mL/min.~* A contraindication to receipt of dobutamine.~* Participants with known coronary artery disease will be included with the exception that patients with left main or narrowings \>50% in the distributions of the left anterior descending, circumflex, and right coronary artery will be excluded.

- Gender: ALL
- Minimum Age: 40 Years
- Maximum Age: 85 Years
- Healthy Volunteers: f

Study Arms:
- A (Type: ACTIVE_COMPARATOR): Arm A will get Dobutamine Stress test with cardiac MR (CMR). Both arms will then cross over to the other arm to get the second test. So each participant will undergo two types of testing.
- B (Type: ACTIVE_COMPARATOR): Arm B will get Regadenoson stress test with CMR. Both arms will then cross over to the other arm to get the second test. So each participant will undergo two types of testing.

Based on this trial design, predict the completion outcome and termination type (if applicable).
