Key result
ECG features including sum of ST-segment elevation, normalization >24 hours, and negative T wave development independently correlated with larger areas of myocardial damage (P<0.001).
Why the study?
Are specific ECG findings associated with the extent of myocardial damage on cardiac MRI in patients with infarct-like acute myocarditis?
Observational (n=41)

Effect estimate: β 0.42-0.49
p-value: p=<0.001
In patients with infarct-like acute myocarditis, specific ECG features such as sum of ST-segment elevation, delayed normalization of STE, and development of negative T waves can help identify those with larger areas of myocardial damage.

Nucifora et al. (2012) conducted an observational in Acute myocarditis with infarct-like presentation (n=41). Electrocardiographic findings (sumSTE, normalization >24 hours, negative T wave) was evaluated on Extent of late gadolinium enhancement (%LV LGE) (β 0.42-0.49, p=<0.001). ECG features including sum of ST-segment elevation, normalization >24 hours, and negative T wave development independently correlated with larger areas of myocardial damage (P<0.001).
