title: [Relation between 1-year mortality after acute myocardial infarction and left ventricular ejection function estimated by echocardiography].
abstract: The pump function of the left ventricle was characterized by means of early echocardiographic determination of the motion of the ventricular walls (wall motion index, WMI) in a consecutive unselected series of 195 patients with acute myocardial infarction. The pump function, WMI, was related to one-year mortality after infarction. The patients were subdivided prospectively into three risk groups (low, middle and high) depending on WMI. One-year mortality in the three groups were 2%, 34% and 37%, respectively (p less than 0.0001). Patients with previous infarcts had significantly lower WMI and greater one-year mortality than patients with first infarct (p less than 0.001 and less than 0.05, respectively). Among patients with first infarct with inferior localization, significantly higher WMI and lower one-year mortality were found than with anterior localization (p less than 0.001 and = 0.15, respectively, (NS)). Women had significantly higher one-year mortality than men (30.2% compared with 16.9% (p less than 0.04)) although this was reflected by a corresponding difference in WMI. Regardless of sex, age, localization of the infarct and signs of residual ischaemia, patients who were allocated to the low risk group solely on the basis of WMI, had particularly good prognoses. Among patients with more extensive myocardial damage, WMI less than or equal to 1.3, other risk factors probably played a greater role.
