Suggests non-contracting segments drive post-MI LVEF reduction; leaves open prospective validation for risk stratification.
Observational (n=34)
The extent of the non-contracting segment of the left ventricle significantly correlates with and contributes largely to the reduction of ejection fraction in patients with acute myocardial infarction.
Hori et al. (1979) conducted an observational in acute myocardial infarction (n=34). Infarct size estimated from total CK released was evaluated on Correlation between infarct size (extent of non-contracting segment) and left ventricular ejection fraction. The extent of the non-contracting segment significantly correlated with left ventricular ejection fraction in 21 patients with akinesis and/or dyskinesis after acute myocardial infarction.
