Relationship between late potentials and myocardial viability assessed by dobutamine echocardiography in the early postinfarction period

Abstract

In patients with an acute myocardial infarction and with low ejection fraction (<40%), the absence of LPs is related to the presence of viable myocardium as assessed by DSE early after the acute event. These data also suggest that myocardial viability is not the substrate for LPs in this population.
