Early or deferred cardiovascular magnetic resonance after ST-segment-elevation myocardial infarction for effective risk stratification
Why the study?
Although CMR holds potential to improve risk stratification beyond the TIMI risk score in STEMI, the optimal timing for CMR after STEMI remains poorly defined.
Does the timing of CMR (early, deferred, or paired) after STEMI affect its prognostic performance for predicting death and HF hospitalization?

Implication
CMR timing after STEMI appears interchangeable for prognosis; hypothesis-generating and should not yet alter practice.
Structured PICO
Does the timing of CMR (early, deferred, or paired) after STEMI affect its prognostic performance for predicting death and HF hospitalization?
P
Population
492 reperfused ST-segment-elevation myocardial infarction (STEMI) patients
I
Intervention
Prognostic stratification using early post-STEMI cardiovascular magnetic resonance (CMR) (median 4 days), deferred CMR (median 4.8 months), or paired CMRs
C
Comparator
Comparison among the three CMR timing stratification models
O
Outcome
Composite of all-death and heart failure (HF) hospitalizationcomposite
Early, deferred, or paired CMR strategies provide equivalent prognostic value for predicting death and heart failure hospitalization in reperfused STEMI patients.
