Key result
Acute anterior myocardial infarction with apical involvement was associated with a significantly lower left ventricular ejection fraction (38.6% vs 52.3%) and higher V4-V5 QRS scores compared to anterior infarction alone.

No
Absolute Event Rate: 38.6% vs 52.3%
p-value: p=<0.02
A QRS scoring system, specifically V4QRSs + V5QRSs, is useful for diagnosing acute apical infarction, which is associated with lower LVEF compared to anterior infarction alone.
Apical involvement in anterior MI may flag higher-risk cases; leaves open whether V4-V5 QRS scoring adds prognostic value beyond imaging.
No takes yet. Share an insight, caveat, or question.
Seino et al. (1986) conducted an observational in Acute myocardial infarction (n=56). Acute apical infarction (AAp) vs. Anterior infarction without apical involvement (A) was evaluated on Left ventricular ejection fraction (LVEF) (p=<0.02). Acute anterior myocardial infarction with apical involvement was associated with a significantly lower left ventricular ejection fraction (38.6% vs 52.3%) and higher V4-V5 QRS scores compared to anterior infarction alone.
