Key result
WMSI >1.8 predicts ~750% higher mortality and HF rehospitalization risk post-MI, outperforming LVEF.
Why the study?
Does wall motion score index predict cardiovascular events better than left ventricle ejection fraction in patients after an acute myocardial infarction?
Cohort (n=352)
Does wall motion score index predict cardiovascular events better than left ventricle ejection fraction in patients after an acute myocardial infarction?
Effect estimate: HR 8.5 (95% CI 3.7-18.8)
p-value: p=<0.0001
Wall motion score index is a superior prognostic predictor compared to left ventricular ejection fraction for cardiovascular events after acute myocardial infarction, particularly in patients with less severe myocardial damage.

WMSI may refine post-MI risk stratification beyond LVEF; hypothesis-generating and requires prospective validation before practice change.
Jurado‐Román et al. (2016) conducted a cohort in acute myocardial infarction (n=352). Wall motion score index vs. Left ventricle ejection fraction was evaluated on Combined endpoint of mortality and rehospitalization for heart failure (HR 8.5, 95% CI 3.7-18.8, p=<0.0001). A wall motion score index >1.8 strongly predicted mortality and heart failure rehospitalization after myocardial infarction (HR 8.5; 95% CI 3.7-18.8; p<0.0001), demonstrating superiority over LVEF.
