Key result
Non-concave ST-segment elevation morphology on ECG strongly suggests acute myocardial infarction in adult emergency department chest pain patients, with a sensitivity of 77% and specificity of 97%.
Why the study?
Does non-concave ST-segment elevation morphology accurately diagnose acute myocardial infarction in adult emergency department patients with chest pain?
Observational (n=599)
Does non-concave ST-segment elevation morphology accurately diagnose acute myocardial infarction in adult emergency department patients with chest pain?
Effect estimate: Sensitivity 77%, Specificity 97%
Non-concave ST-segment elevation morphology on ECG is highly specific (97%) and has a high positive predictive value (94%) for diagnosing acute myocardial infarction in emergency department patients with chest pain.

May aid ruling in AMI on ED ECG; leaves open prospective validation before practice change.
Brady et al. (2001) conducted an observational in Acute myocardial infarction (n=599). Non-concave ST-segment elevation morphology analysis vs. Concave ST-segment elevation morphology was evaluated on Diagnosis of acute myocardial infarction (Sensitivity 77%, Specificity 97%). Non-concave ST-segment elevation morphology on ECG strongly suggests acute myocardial infarction in adult emergency department chest pain patients, with a sensitivity of 77% and specificity of 97%.
