Key result
Lead V1 ST elevation in anterior MI is linked to ~96% higher basal anterior dysfunction.
Why the study?
The relationship between admission ECG ST elevation in various leads and regional wall motion abnormalities in first anterior acute myocardial infarction was unclear.
Does ST elevation in specific admission ECG leads correlate with regional wall motion abnormalities on echocardiography in patients with first anterior acute myocardial infarction?
Observational (n=132)
Does ST elevation in specific admission ECG leads correlate with regional wall motion abnormalities on echocardiography in patients with first anterior acute myocardial infarction?
Absolute Event Rate: 49% vs 25%
p-value: p=0.006
ST elevation in lead V1 during an anterior myocardial infarction correlates with a higher incidence of basal anterior, anteroseptal, and septal regional dysfunction on echocardiography.
May link specific ST patterns to regional dysfunction in anterior MI; hypothesis-generating and requires validation before any clinical use.
We correlated ST elevation in various leads on admission and regional dysfunction in 132 patient with first anterior acute myocardial infarction using echocardiography. ST elevation in leads I and a VL and II, III and aVF was not associated with a specific pattern of regional dysfunction. Basal anterior and septal regional dysfunction were seen more often in patients with ST elevation in V1 (49 vs. 25%, p = 0.006; 35 vs. 17%, p = 0.048, respectively). Patients with ST elevation in V2 had more regional dysfunction of the apical inferior region (84 vs. 53%; p = 0.01). ST elevation in V5 and V6 was not associated with more apical or lateral wall motion abnormalities. ST elevation in lead V1 in anterior myocardial infarction is associated with a high incidence of regional dysfunction of the basal anterior, anteroseptal and septal regions.

Porter et al. (2000) conducted an observational in First anterior acute myocardial infarction (n=132). ST elevation in lead V1 vs. Absence of ST elevation in lead V1 was evaluated on Basal anterior regional dysfunction (p=0.006). ST elevation in lead V1 on admission in anterior myocardial infarction is associated with a higher incidence of basal anterior regional dysfunction (49% vs 25%, p=0.006).
