Key result
In patients with acute anterior myocardial infarction, the sum of precordial ST segment elevations was significantly higher on admission compared to normal controls (p<0.01), and secondary re-elevations correlated with clinical worsening suggestive of infarct extension.
Population
30 patients with acute anterior myocardial infarction (27 transmural and 3 subendocardial)

Serial precordial mapping in acute anterior myocardial infarction can identify re-elevation of ST segments, which correlates with infarct extension and worse clinical outcomes.
Gulati et al. (1977) conducted an observational in Acute anterior myocardial infarction (n=41). Precordial ST segment mapping vs. Normal controls was evaluated on Mean sum of ST segment elevations (Σ ST) on admission in male patients (p=<0.01). In patients with acute anterior myocardial infarction, the sum of precordial ST segment elevations was significantly higher on admission compared to normal controls (p<0.01), and secondary re-elevations correlated with clinical worsening suggestive of infarct extension.
