Secondary ST re-elevation >0.6 mV/hr was associated with necrosis extension; leaves open the value of serial monitoring in anterior MI.
Does the spontaneous course of ST-segment elevation correlate with extension of necrosis in patients with acute anterior myocardial infarction?
A secondary increase in ST-segment elevation >0.6 mV/hr is a reliable indicator of infarct extension in acute anterior myocardial infarction, suggesting physicians should monitor for this increase rather than just a decrease.
Essen et al. (1979) studied this question.
