Key result
Moderate systolic dysfunction (LVEF ≥30% and <45%) independently predicted the recovery of depressed left ventricular ejection fraction after acute myocardial infarction (OR 1.73).

In patients with depressed LVEF after acute myocardial infarction, recovery of systolic function is independently predicted by less severe initial heart failure, smaller infarct size, non-LAD culprit lesions, and statin therapy.
Oh et al. (2013) conducted an observational in Moderate or severe left ventricular systolic dysfunction after acute myocardial infarction (n=1,307). Moderate systolic dysfunction (LVEF ≥30% and <45%) vs. Severe systolic dysfunction (LVEF <30%) was evaluated on Recovery of depressed LVEF (≥45%) at follow-up echocardiography (OR 1.73, 95% CI 1.12-2.67, p=0.013). Moderate systolic dysfunction (LVEF ≥30% and <45%) independently predicted the recovery of depressed left ventricular ejection fraction after acute myocardial infarction (OR 1.73).
