Utility of cardiovascular magnetic resonance in patients with stable troponin elevation
Authors' conclusion
CMR identified a cause for stable troponin elevation in 7 of 10 cases, and a new diagnosis was evident in 1 of 4 cases. CMR improved the net reclassification of patients with stable troponin elevation.
