Usefulness of two-dimensional exercise echocardiography shortly after XXXX .

@entity1 @entity63 @entity951 @entity453 @entity583
To determine the clinical significance of transient remote asynergy after the first @entity583 ( @entity583 ), 2-dimensional echocardiography was performed at rest and directly after dynamic exercise in 49 consecutive @entity1 within 3 weeks of @entity583 . In 43 @entity1 (88%), technically adequate 2-dimensional echocardiographic examinations were obtained. Asynergy was found in all @entity1 at rest. Immediately after exercise, new areas of asynergy, not adjacent to the infarcted area (i.e., transient remote asynergy), were present in 18 @entity1 . Of these @entity1 , 17 had multivessel @entity453 ( @entity453 ), compared with 5 of 25 @entity1 without transient remote asynergy. Sensitivity of transient remote asynergy for detecting multivessel @entity453 was 77% and specificity was 95%. Left ventricular ejection fraction at rest and after exercise was measured in 39 @entity1 (90%) and could only identify @entity1 with 3-vessel @entity453 . New @entity63 events, defined as reinfarction or recurrent @entity951 , within a mean of 12 weeks (range 8 to 16) after discharge, occurred in 16 @entity1 . Transient remote asynergy was present in 12 of these @entity1 (75%). It is concluded that exercise-induced transient remote asynergy early after @entity583 can identify @entity1 with multivessel @entity453 and a subgroup of @entity1 prone to early new @entity63 events. Left ventricular ejection fraction, however, is not only more laborious but also of lesser value in identifying @entity1 with multivessel @entity453 .
