Key result
In patients with anterior MI, larger infarct size (peak CK ≥8000 U/L) was associated with a significantly greater left ventricular expansion ratio at 14 days compared to smaller infarcts (p<0.05).

Early serial 2DE may guide infarct-size-based hospital stay after anterior MI; supports echocardiography for forecasting chronic LV function in practice and trials.
Cohort (n=45)
p-value: p=<0.05
Serial two-dimensional echocardiography on days 1 and 14 after myocardial infarction is useful for evaluating the course of left ventricular remodeling and forecasting chronic cardiac function.
Sakai et al. (2000) conducted a cohort in anterior myocardial infarction (n=45). Large infarct size (peak CK ≥8000 U/L) vs. Small infarct size (peak CK <4000 U/L) was evaluated on Expansion ratio (endocardial length at 14 days/1 day) (p=<0.05). In patients with anterior MI, larger infarct size (peak CK ≥8000 U/L) was associated with a significantly greater left ventricular expansion ratio at 14 days compared to smaller infarcts (p<0.05).
