Brief Summary:
This is a pilot study to determine whether coronary magnetic resonance angiography(CMRA)can identify adverse plaque characteristics (buildup of fat, cholesterol, calcium, and other substances found in the blood) seen on coronary computed tomography angiography(CCTA) and evaluate whether there is a relationship between the adverse plaque characteristics and the presence of coronary artery wall inflammation.

Condition or disease Intervention/treatment Phase
Coronary Artery Disease Other: Coronary MR Angiography (CMRA) Not Applicable

Detailed Description:

This pilot study will examine 20 stable patients who have undergone a clinically-indicated coronary computed tomography angiography (CCTA) for suspected Coronary Artery Disease. They will be invited to undergo a research coronary Magnetic Resonance Imaging scan with contrast(CMRA). Based upon the subject's heart rate, a beta blocker may be administered as its use has been shown to be effective in producing better images as it widens the arteries.

Researchers will use newly developed non-invasive coronary MRA techniques to compare information shown on the research CMRA with the clinical CCTA. While CCTA has been demonstrated to be able to provide data on adverse plaque characteristics (APC's), the ability of CMRA to evaluate these features is not established.

Arm Intervention/treatment
Coronary MR Angiography (CMRA)
Coronary MR Angiography(CMRA). A gadolinium-based contrast (Optimark or MultiHance) will be administered as well as a beta blocker which will be assigned based upon heart rate.
Other: Coronary MR Angiography (CMRA)
Stable patients who have undergone a clinically indicated CCTA study for suspected Coronary Artery Disease will undergo a research CMRA with contrast (Multihance or Optimark)total dose of up to 0.2 mmol/kg IV. Possible administration of oral beta-blocker (metoprolol)intravenous doses of 5mg IV metoprolol may be given every 2 minutes up to a maximal dose of 15 mg IV.

  • MR Imaging
  • MR angiography

Primary Outcome Measures :
  1. Adverse plaque characteristics present on CMRA [ Time Frame: one day ]

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Age ≥18 years
  • Ability to comprehend and sign informed consent
  • Presence of a non-calcified or mixed plaque without high-grade stenosis in the left main or a proximal coronary artery segment AND at least one APC present in this plaque by CCTA (defined as LAP with <30 Hounsfield units or PR with ≥10% increase in the maximal vessel diameter within the plaque as compared to a proximal reference segment as previously described10).

  • Significant asthma
  • History of 2nd or 3rd degree heart block
  • Allergy or known intolerance to beta-blockers
  • Use of phosphodiesterase inhibitor (e.g. Viagra) within the last 48 hours
  • Rapid heart rate (heart rate ≥90 beats/minute)
  • Severe aortic stenosis (Aortic valve area <1.0 cm2 or mean gradient >30 mmHg)
  • Systolic blood pressure <100 mmHg
  • Other contraindication to MRI, including metallic implants (valve replacement, pacemaker, implantable cardiac defibrillator, metallic spine material), intracranial clips, metallic fragments in eyes, and claustrophobia
