Key result
Anterior myocardial infarction was associated with more pronounced right ventricular dysfunction compared to inferior MI, evidenced by a higher tricuspid E/E' ratio (6.73 vs 5.68, P=0.01).
Why the study?
Does anterior myocardial infarction result in worse right ventricular function compared to inferior myocardial infarction in patients with a first acute ST-elevation MI?
Observational (n=60)
Does anterior myocardial infarction result in worse right ventricular function compared to inferior myocardial infarction in patients with a first acute ST-elevation MI?
Absolute Event Rate: 6.73% vs 5.68%
p-value: p=0.01
Echocardiographic assessment reveals that right ventricular dysfunction is common after a first acute ST-elevation MI, but functional changes are more pronounced in patients with anterior MI compared to inferior MI.

Should not yet change post-MI RV assessment; hypothesis-generating and requires prospective validation.
Abtahi et al. (2016) conducted an observational in Myocardial Infarction (n=60). Anterior myocardial infarction vs. Inferior myocardial infarction was evaluated on Ratio of early diastolic velocity of the tricuspid flow to early diastolic velocity of the tricuspid annulus in the lateral side (E/E') (p=0.01). Anterior myocardial infarction was associated with more pronounced right ventricular dysfunction compared to inferior MI, evidenced by a higher tricuspid E/E' ratio (6.73 vs 5.68, P=0.01).
