BACKGROUND: The aim of this study was to test the usefulness of two-dimensional longitudinal strain pattern in segments with wall motion abnormalities to predict left ventricular recovery and in-hospital @entity299 as well as @entity301 ( @entity301 ) in @entity1 with recent acute anterior @entity583 . METHODS: Forty-nine consecutive @entity1 with @entity583 (mean age, 59      13  years) treated successfully with primary coronary angioplasty prospectively underwent transthoracic Doppler echocardiography 24  hours after angioplasty and during follow-up (6  months). A two-dimensional strain analysis, including measurement of the duration of systolic lengthening expressed as a percentage of systolic duration (SL % duration), the lengthening-to-shortening ratio, the postsystolic shortening index in segments with wall motion @entity66 and left anterior descending coronary artery territory strain, was performed. @entity299 were defined as a composite of death, reinfarction, and @entity712 . @entity301 was assessed noninvasively by transthoracic Doppler left anterior descending coronary artery investigation <24  h after angioplasty and was defined as coronary flow velocity reserve  <  1.7 and/or a no-reflow pattern (mean coronary flow velocity reserve, 1.8      0.6 in the whole group). RESULTS: At the segmental level, SL % duration, lengthening-to-shortening ratio, and postsystolic shortening index were correlated with recovery (defined as normalization of wall motion abnormalities), whereas in multivariate analysis, only SL % duration independently predicted recovery (threshold level, 40%; area under the curve, 0.76; P  <  .01). At the @entity1 level, in univariate analysis, SL % duration, @entity6475 , left anterior descending coronary artery territory strain, and troponin peak were correlated with recovery (defined as an absolute improvement of left ventricular ejection fraction of >5%). In multivariate analysis, SL % duration was independently related to recovery (area under the curve, 0.78; P  <  .01). Furthermore, SL % duration was independently linked to @entity299 (n  =  13) and @entity301 (n  =  24) (P  <  .01 for all). CONCLUSIONS: In @entity1 with AMI treated by primary angioplasty, two-dimensional strain predicts left ventricular recovery independently of more traditional parameters and is independently linked to @entity299 and @entity301 .
