Key result
Infarct transmurality >50% and average necrosis index of dysfunctional segments on MRI were significant factors determining the presence of a pathologic Q wave in acute myocardial infarction.
Why the study?
Does the presence of a pathologic Q wave on ECG correlate with infarct transmurality and myocardial necrosis index assessed by MRI in patients with acute myocardial infarction?
Observational (n=38)
Does the presence of a pathologic Q wave on ECG correlate with infarct transmurality and myocardial necrosis index assessed by MRI in patients with acute myocardial infarction?
An infarct transmurality over 50% and average necrosis index of dysfunctional segments are significant factors in the genesis of a pathologic Q wave in acute myocardial infarction.
No takes yet. Share an insight, caveat, or question.
Pathologic Q waves do not reliably indicate transmural infarction; challenges traditional ECG interpretation and supports MRI for precise infarct assessment in acute MI.
Park et al. (2004) conducted an observational in acute myocardial infarction (n=38). Pathologic Q wave on ECG vs. No pathologic Q wave on ECG was evaluated on Infarct transmurality and average necrosis index of dysfunctional segment (ANI). Infarct transmurality >50% and average necrosis index of dysfunctional segments on MRI were significant factors determining the presence of a pathologic Q wave in acute myocardial infarction.
