Key result
Both WMSI > 1.5 and LVEF < 40% significantly predicted all-cause mortality (p<0.0001), while WMSI was a superior predictor for heart failure readmission (p=0.002) compared to LVEF (p=0.2).
Why the study?
LVEF and wall motion score index both assess left ventricular function, but their comparative value for predicting all-cause mortality and heart failure readmission after acute myocardial infarction needed evaluation.
Does Wall Motion Score Index (WMSI) predict all-cause mortality and heart failure readmission better than Left Ventricular Ejection Fraction (LVEF) in patients with acute myocardial infarction?

Does Wall Motion Score Index (WMSI) predict all-cause mortality and heart failure readmission better than Left Ventricular Ejection Fraction (LVEF) in patients with acute myocardial infarction?
Wall Motion Score Index (WMSI) is a superior predictor for heart failure-related readmissions compared to LVEF in patients following an acute myocardial infarction, while both effectively predict all-cause mortality.
No takes yet. Share an insight, caveat, or question.
WMSI may better predict HF readmission than LVEF post-AMI; leaves open validation before changing risk stratification.
Venkateshwaran et al. (2023) conducted a cohort in Acute Myocardial Infarction (n=54). Wall Motion Score Index (WMSI) > 1.5 and Left Ventricular Ejection Fraction (LVEF) < 40% vs. WMSI ≤ 1.5 and LVEF ≥ 40% was evaluated on Composite of all-cause mortality and readmission for heart failure. Both WMSI > 1.5 and LVEF < 40% significantly predicted all-cause mortality (p<0.0001), while WMSI was a superior predictor for heart failure readmission (p=0.002) compared to LVEF (p=0.2).
