Abstract

BACKGROUND

ECG is widely used in the evaluation of patients with acute myocarditis. Magnetic resonance imaging (MRI) has emerged as the most important imaging tool in the diagnosis of myocarditis. The objective of this study is to determine the agreement between ECG and MRI findings in patients with acute myocarditis.

METHODS

This is a retrospective cohort that includes 32 consecutive patients with acute myocarditis. ST elevation (STE) in mm was registered in every ECG lead. In every myocardial segment the presence of late enhancement (LE) was registered.

RESULTS

STE was found in 75% of the patients, with the inferolateral region being the most frequently affected (46.9%). LE was found in most of the patients (87.5%); the inferolateral wall was also the most frequently affected (50%). There was a moderate agreement between the inferolateral localization of STE and LE in patients with acute myocarditis, k = 0.43, p = 0.01. There was no agreement for the other localizations.

CONCLUSION

There was a moderate agreement between the localization of STE and LE only in the inferolateral localization. LE localization based on the STE localization cannot be inferred, neither vice versa in another localization different from the inferolateral.
