Abstract
Background A surprising proportion of troponinpositive chest pain patients referred for contrast coronary angiography exhibit no or minor coronary arterial luminal narrowings at the time of presentation. We assessed whether the presence of late gadolinium enhancement (LGE) during cardiovascular magnetic resonance (CMR) forecasts adverse cardiovascular (CV) events in patient presenting with serum troponin elevations and chest pain but without obstructive coronary artery disease during contrast coronary angiography.

A surprising proportion of troponin- positive chest pain patients referred for contrast coronary angiography exhibit no or minor coronary arterial luminal narrowings at the time of presentation
We assessed whether the presence of late gadolinium enhancement (LGE) during cardiovascular magnetic resonance (CMR) forecasts adverse cardiovascular (CV) events in patient presenting with serum troponin elevations and chest pain but without obstructive coronary artery disease during contrast coronary angiography
CMR with LGE was performed in 77 consecutive patients who had been referred for CMR after presenting with new-onset chest pain, and an elevated serum troponin-I without coronary arterial luminal narrowings > 49% during contrast coronary angiography
