Early sigmaST decline after anterior MI cautions against unadjusted serial use; supports matched controls in short-term intervention trials.
What is the variability and reproducibility of precordial ST-segment mapping in patients with acute anterior myocardial infarction?
Precordial ST-segment mapping shows significant variability over time after acute MI, but remains useful for evaluating short-term therapeutic interventions if control groups are carefully matched.
