Supports infarct size as key driver of early post-MI LV dysfunction; leaves open whether %ACS assessment improves risk stratification or management.
How do segmental left ventricular wall motion abnormalities relate to overall LV function in patients 2-6 days after acute transmural myocardial infarction?
The size of abnormally contracting segments is a major determinant of left ventricular dysfunction in acute myocardial infarction, strongly correlating with ejection fraction.
Rigaud et al. (1979) studied this question.
