Usefulness of contrast echocardiography for predicting the severity of angiographic coronary disease in XXXX .

Guidelines recommend coronary angiography in @entity1 with @entity583 ( @entity583 ) within 24 to 72 hours, a requirement that cannot always be met. The aim of this study was to evaluate the potential use of contrast echocardiography in prioritizing these @entity1 by identifying those with @entity583 and angiographically severe @entity453 ( @entity453 ). Echocardiography was performed before coronary angiography in 110 @entity1 with @entity583 (67    12 years old, 31% @entity1 ). Segmental myocardial perfusion and wall motion was scored using a 17-segment left ventricular model. @entity453 was assessed by quantitative coronary angiography. In the total study population, median troponin T level was 0.27  g/L (0.13 to 0.86) and Thrombolysis In @entity583 risk score 3.1    1.5. By quantitative coronary angiography 15% had normal coronary angiographic findings, whereas 1-, 2-, and @entity66 were present in 35%, 27%, and 23%, respectively. Severe @entity453 (left main stem @entity850 , @entity66 , or multivessel disease including proximal @entity850 in left anterior descending artery) was found in 42%. Number of segments with hypoperfusion increased with @entity453 severity from 4.1    2.0 in @entity1 with normal coronary arteries to 5.9    2.4, 7.8    3.5, and 10.4    2.8 in @entity1 with 1-, 2-, and @entity66 , respectively (p<0.01). In multiple logistic regression analysis risk of severe @entity453 increased by 39% for every additional hypoperfused segment by echocardiography independent of wall motion abnormalities and Thrombolysis In @entity583 risk score. In conclusion, contrast echocardiography may be used for prediction of angiographic @entity453 severity in @entity1 with @entity583 awaiting coronary angiography.
