Evolution of regional left ventricular wall motion abnormalities in acute Q and non-Q wave XXXX .

@entity1 @entity662 @entity63 @entity1188 @entity583
The evolution of segmental wall motion in Q and non-Q wave @entity583 was studied in detail in 15 @entity1 without known prior @entity63 events. Serial two-dimensional echocardiographic studies were performed beginning early after the onset of @entity662 and continuing until 10 to 14 days after admission. An area of apparent @entity1188 was identified on each initial study based on later correlation of ECG and echocardiographic findings. Wall motion of @entity1188 -and noninfarct-related areas was graded in a semiquantitative fashion based on the scoring of a visual analysis. Sequential image data demonstrated significant spontaneous improvement in wall motion of the @entity1188 area in non-Q but not in Q wave events. @entity1 with non-Q wave @entity1188 and improvement in regional function were at high risk for recurrent @entity1188 within 6 months. Improvement in wall motion inside or outside the area of @entity1188 in Q wave events was related to future risk. We concluded that in @entity1 with initial @entity583 , failure to develop Q waves correlated with return of function in the apparent area of @entity1188 . Improvement in regional wall motion after the initial study suggested risk for future @entity63 events in both ECG types of @entity583 . Serial echocardiographic imaging may be a means to identify @entity1 at risk for @entity1188 extension in both non-Q and Q wave events.
