Why the study?
Does the magnitude of ST-segment elevation predict adverse clinical outcomes in patients with acute myocardial infarction?
Population
404 patients admitted to the hospital with their first myocardial infarction within 24 hours of symptom onset.
Comparison
Major ST-segment elevation on 12-lead ECG vs Minor ST-segment elevation on 12-lead ECG
Design

Major ST-elevation may aid AMI risk stratification for monitoring; supports prognostic value but leaves open prospective validation.
Does the magnitude of ST-segment elevation predict adverse clinical outcomes in patients with acute myocardial infarction?
The magnitude of ST-segment elevation in acute myocardial infarction provides valuable prognostic information for identifying patients at high risk of adverse events who may require prolonged monitoring.
