Abstract

Regional left ventricular wall motion was evaluated by two-dimensional echocardiographic technique with floating-axis (internal frame of reference) system in three groups of subject; normal subject (n=12), patients with acute anterior myocardial infraction(n=16), and patients with acute inferior myocardial infraction(n=10).
Significant hypokinetic wall motion were detected in apical portion (Mean Percent Shortening; 0.27-5.84% in anterior infraction group and 9.64-13.17% in controls) and apicoanterior portion (MPS; 2.86% in anterior infraction group and 14.13% in controls) in patients with acute anterior myocardial infraction (P<0.01), and inferior portion (MPS; 3.56-6.93% in inferior infraction group and 18.26-19.8% in controls) and apical portion (MPS; 4.04% in inferior infraction group and 9.64% in controls) in patients with acute inferior myocardial infraction (P<0.01) in apical long-axis views.
We conclude that echocardiographic wall motion analysis by floating axis system is an accurate non-invasive method for detecting abnormal wall motion in patients with acute anterior and in ferior myocardial infraction.
