Overview
Cardiac magnetic resonance (CMR) is a useful imaging modality in distinguishing between stress cardiomyopathy and myocarditis or MI. The most common findings on CMR in patients with stress cardiomyopathy include absence of gadolinium hyper-enhancement, as well as myocardial edema.[1][2][3][4][5][6][7][8][9][10][11]

Cardiac Magnetic Resonance (CMR)
Cardiac magnetic resonance (CMR) is a useful imaging modality in distinguishing between stress cardiomyopathy and myocarditis or MI. In the case of myocarditis or MI, there is delayed hyper-enhancement of gadolinium. However, absence of gadolinium hyper-enhancement supports the diagnosis of stress cardiomyopathy. Also, stress cardiomyopathy results in regional wall abnormality and its extent can best be documented using cardiac magnetic resonance.[1][2][3][4][5][6][7][8][9][10][11] CMR in stress cardiomyopathy shows absence of irreversible damage and segmental LV dysfunction.[4]
Other findings on CMR include:[12][13]
- Hypokinetic or dyskinetic areas in the wall of the heart
- Myocardial edema
- Apical thrombi
MRI Examples
The MRIs below show a patients heart with apical ballooning and then later after resolution of the apical ballooning.
