Key result
CMR area-at-risk and myocardial salvage index predict LV functional recovery three months post-STEMI.
Why the study?
LV GLS predicts adverse events after myocardial infarction, but the ability of infarcted myocardium morphological features to detect acute LV dysfunction and predict LV recovery was investigated.
Do morphological features of infarcted myocardium assessed by CMR predict left ventricular functional recovery at three months in patients with acute STEMI?

May aid post-STEMI risk stratification via acute CMR; hypothesis-generating and requires prospective validation before clinical use.

Do morphological features of infarcted myocardium assessed by CMR predict left ventricular functional recovery at three months in patients with acute STEMI?
p-value: p== 0.020
CMR-derived area-at-risk and myocardial salvage index assessed during the acute stage of STEMI can predict left ventricular functional recovery at 3 months.
Virbickiene et al. (2023) conducted a cohort in Acute ST-segment elevation myocardial infarction (STEMI) (n=66). Cardiac Magnetic Resonance (CMR) assessment was evaluated on Left ventricular functional recovery (LVEF, LV GLS, LV GCS) at three months (p== 0.020). Area-at-risk assessed by CMR predicts improvement in LVEF and LV GLS, while myocardial salvage index predicts LV GCS recovery at 3 months post-STEMI (P=0.020).
