Prognostic value of segmental contractility assessed by cross-sectional echocardiography in first acute myocardial infarction

We prospectively studied 110 patients with a first acute myocardial infarction with cross–sectional echocardiography, between 7–10 days post–infarction, to assess the value of semiquantitative segmental con–tractility score for the first year post–AM I risk stratification. 87 patients had acceptable recordings (40 anterior and 47 inferior infarction). Twelve patients had severe complications (severe angina or heart failure, reinfarction or death) and 40 had nonsevere complications. The total segmental score was higher in complicated than in non–complicated patients. The score also differentiated angina from heart failure. The score of necrotic area was more discriminating than that of non-necrotic area. Discriminating power was higher in anterior than in inferior acute myocardial infarction. Thus we conclude that the semiquantitative assessment of segmental contractility by cross–sectional echocardiography is useful for risk stratification following acute infarction identifying severe complications, particularly heart failure, with better discrimination in anterior acute myocapdial infarction.
