Prediction of the extent of @entity453 with the evaluation of left ventricular wall motion abnormalities during XXXX . A cross-sectional echocardiographic study.

@entity1 @entity583 @entity66 @entity301 @entity3979 @entity955 @entity453 @entity850
In @entity1 with @entity453 , left ventricular performance during stress is affected by the degree of @entity3979 . In order to verify whether there exists a relationship between the extent of wall motion abnormalities detectable during @entity955 and the degree of @entity301 , 76 @entity1 , without previous @entity583 , were studied. Each @entity1 underwent cross-sectional echocardiography during transesophageal @entity955 and exercise electrocardiography before coronary angiography. Of the 76 @entity1 , 46 had significant @entity453 ( @entity850 greater than or equal to 75% of at least one major coronary vessel), while 30 had normal coronaries or a @entity850 of less than 75%. Eighteen @entity1 had single-, 14 had two- and 14 had @entity66 . For each @entity1 a coronary score was obtained: the score used took into consideration the site, number and severity of the @entity850 . This score was then correlated with the wall motion score, obtained from the analysis of 9 segments of the left ventricle. A weak correlation was obtained between wall motion score at rest and coronary score (r = -0.42), while the correlation between coronary score and the difference between wall motion score at rest and during transesophageal @entity955 was slightly better (r = 0.53); this correlation further improved if wall motion score during pacing was considered (r = -0.63). If the @entity1 with discordant diagnostic tests (echocardiography during transesophageal @entity955 and exercise electrocardiography) were excluded, the correlation coefficient between coronary score and wall motion score during pacing increased even more (r = -0.77). IN CONCLUSION: (1) analysis of wall motion of the left ventricle during @entity955 is useful for the non-invasive evaluation of the severity of @entity301 ; (2) cross-sectional echocardiography during @entity955 , apart from being a useful diagnostic tool, is also a help in judging the degree of severity of @entity453 .
