The relation between left ventricular wall thick-ness and wall motion abnormalities in acute myocardial infarction (AMI) was studied using 2-dimensional echocardiography (2-D echo).

2-D echo was obtained in 37 cases of AMI within 23.6±22.3 hr (acute phase) and one month later. The akinetic myocardial segments less than 7mm thick in diastole in acute phase were still akinesis one month later, while the akinetic or hypokinetic segments more than 8mm thick in acute phase be-came hypokinesis or normokinesis one month later. The extent of akinesis segments less than 7mm thick was significantly correlated with peak CPK (r=0.79) and ejection fraction provided by the gated cardiac blood pool scan (RIEF) one month after the attack (r=-0.72). In antero-septal myo-cardial infarction, the extent of akinetic segments less than 7mm thick was significantly correlated with nQ (r=0.73), wall motion index and the extent of wall motion abnormalities were correlated with nST (r=0.78, r=0.72) of 36 leads mapping electrocardiogram. On the other hand, wall motion index in acute phase of AMI was less significantly correlated with peak CPK (r=0.60), RIEF (r= -0.57), and nQ (r=0.55).

Consequently, it can be concluded that extent of akinetic segments less than 7mm thick indicate the necrotic zone more precisely in acute phase of myocardial infarction and cardiac function one month after onset can be estimated by the extent of these segments.
