Prior MI may warrant cautious ST-elevation interpretation; hypothesis-generating for refined ECG criteria in post-MI patients.
Does a history of prior myocardial infarction affect the predictive value of ST segment elevation or depression for diagnosing acute evolving myocardial infarction in patients with chest pain?
A history of prior myocardial infarction significantly reduces the positive predictive value of ST segment elevation for acute MI due to false-positive acute injury patterns in areas of prior Q wave infarction.
