Effect of prior XXXX and extent and location of @entity301 on accuracy of exercise echocardiography.

@entity1 @entity583 @entity66 @entity301 @entity3979 @entity1188 @entity453
Exercise echocardiography is an emerging technique for the evaluation of @entity1 with suspected @entity453 . In this study, rest and immediate postexercise echocardiograms were performed in 123 @entity1 who were stratified on the basis of prior @entity583 and the number and location of @entity3979 at cardiac catheterization. The location of wall motion abnormalities on rest and postexercise studies was correlated with the location of @entity3979 . The sensitivity of exercise echocardiography for detecting @entity453 in @entity1 with multivessel disease was 97% in those with and 86% in those without prior @entity1188 . The corresponding sensitivity for @entity1 with @entity66 was 100% and 72%, respectively. Multivessel disease was present in 59 @entity1 , but specifically identified as such in only 32 (54%). Normal rest and exercise echocardiograms were seen in 12 @entity1 with @entity453 , 8 of whom had @entity66 . It is concluded that the subjective analysis of the exercise echocardiogram accurately identifies the majority of @entity1 with @entity453 . Its sensitivity is greatest in those with multivessel @entity301 . It is limited in those with single vessel @entity301 and in accurately identifying the subset of @entity1 with multivessel disease.
