Adverse Prognosis of ST Depression on the Resting Electrocardiogram in Stable Patients Following Acute Myocardial Infarction
Why the study?
Does resting ST segment depression predict cardiac death and hospitalization for acute myocardial infarction or unstable angina in stable patients following an acute ischemic event?
Population
936 stable patients following an acute ischemic event, comprising 99 patients with ST depression and 837…
Comparison
Presence of ST segment depression on resting ECG vs Absence of ST segment depression on resting ECG

Implication
ST depression may stratify post-MI risk; leaves open incremental value beyond clinical scores in modern cohorts.
Structured PICO
Does resting ST segment depression predict cardiac death and hospitalization for acute myocardial infarction or unstable angina in stable patients following an acute ischemic event?
P
Population
936 stable patients following an acute ischemic event (infarction or unstable angina), comprising 99 patients with ST depression and 837 patients without ST depression on the resting ECG.
I
Intervention
Presence of ST segment depression on resting ECG
C
Comparator
Absence of ST segment depression on resting ECG
O
Outcome
Cardiac death and hospitalization for acute myocardial infarction or unstable anginahard clinical
Resting ST segment depression on ECG is a marker of adverse prognosis (cardiac death and reinfarction) specifically in patients recovering from acute myocardial infarction, likely reflecting older age and more severe underlying coronary disease.
