By the recordings of the serial echocardiograms of the patients with acute myocardial infarction, analysis of aortic root motion and prognosis in the acute phase was investigated.
The subjects employed were 62 cases, in which 49 alive and 13 died (21%) in the hospital.
(1) Significant correlations were observed between aortic wall excursion (AWE) and stroke volume (r=0.51) .
(2) In most cases, AWE and mean aortic wall velocity (mAWV) on admission were smaller, and they were increased gradually.
(3) In the group with smaller AWE, more cases with heart failure were observed.
(4) AWE was smaller (under 7 mm) in eleven of thirteen died cases. In the group with small AWE, wide left ventricular dimension, wide left atrial dimension, small mitral valve excursion and short PR-AC time, five cases out of six were complicated with heart failure and five out of six died. On the other hand, in the group with normal AWE, left ventricular dimension, left atrial dimension, mitral valve excursion and PR-AC time, only one case was complicated with heart failure and none of them was died and the prognosis for this group was considered to be good.
