We evaluated the prognostic value of cardiac magnetic resonance (CMR) stress testing with direct comparison of adenosine stress first-pass perfusion and dobutamine stress wall motion imaging among 513 subjects with known or suspected coronary heart disease over a median follow-up period of 2.3 years. Positive results on CMR stress testing identified subjects at high risk for subsequent cardiac events (nonfatal myocardial infarction or cardiac death), whereas normal CMR stress test results were associated with a very low annual cardiac event rate.
