Brief Summary:
The purpose of this study is to test the hypothesis of whether contrast enhanced Magnetic Resonance Imaging can be used to predict improvement of the wall motion in regions of the heart with abnormal movement following bypass surgery or percutaneous angioplasty in various institutions across three continents.

Primary Outcome Measures :
  1. To examine whether the extent of irreversible myocardial injury as assessed by Delayed Enhancement Magnetic Resonance Imaging can predict the extent of functional recovery after revascularization in patients with chronic coronary artery disease (CAD). [ Time Frame: 36 months ]

Sampling Method:   Probability Sample
Study Population
Patients were recruited from 9 institutions on 3 different continent. All patients recruited for the study had a history of angiographically documented chronic coronary artery disease and resting wall motion abnormalities, and were scheduled for cardiac revascularization (coronary artery bypass surgery or percutaneous intervention).

Inclusion Criteria:

  • Age: > 21 years and < 85 years
  • Sinus rhythm
  • Weight < 120 kg
  • LVEF > 30%
  • Wall motion abnormality on Echo. or LV-gram
  • Scheduled for revascularization - Angioplasty/Stent or CABG - within 30 days

Exclusion Criteria:

  • Resting heart rate > 100 bpm
  • Frequent atrial or ventricular ectopy
  • Severe aortic stenosis or HOCM
  • Unstable angina
  • Myocardial infarction within 14 days
  • Active congestive heart failure
  • Pregnancy
  • Known allergy to gadolinium
  • Contraindication to MRI
