Key result
LV aneurysm in anterior MI survivors links to higher V1-V6 ST elevations and ~23% mean LVEF.
Why the study?
Does the presence of a left ventricular aneurysm correlate with precordial ST segment elevation in survivors of a first acute anterior Q wave myocardial infarction?
Population
78 consecutive survivors of a first acute anterior Q wave myocardial infarction (AMI)
Design
Cross-sectional

May aid risk stratification for LV aneurysm via summed ST elevation post-anterior MI; leaves open prospective validation before clinical adoption.

Does the presence of a left ventricular aneurysm correlate with precordial ST segment elevation in survivors of a first acute anterior Q wave myocardial infarction?
p-value: p=< 0.01
The sum of precordial ST segment elevations, rather than single lead maximums, correlates with the presence of left ventricular aneurysm after an anterior Q wave MI.
SUDHIR BHATNAGER (1994) conducted an observational in first acute anterior Q wave myocardial infarction (n=78). Left ventricular anteroapical aneurysm vs. No left ventricular aneurysm was evaluated on Sum of ST elevations in V1 to V6 (p=< 0.01). Left ventricular aneurysm in survivors of a first acute anterior Q wave MI was associated with a higher sum of ST elevations in V1-V6 (P<0.01) and a lower mean ejection fraction (23% vs 34%, P<0.001).
