Lower limb pneumatic compression during @entity452 stress echocardiography in XXXX with normal resting wall motion: will it increase the diagnostic accuracy?

@entity1 @entity452 @entity854 @entity3979 @entity453
BACKGROUND: Pneumatic compression of the lower part of the body increases systemic vascular resistance and left ventricular afterload. AIM: We compared the diagnostic accuracy of @entity452 stress echocardiography (DSE) with pneumatic compression of the lower extremities, versus standard DSE, for detection of angiographically significant @entity453 ( @entity453 ) in @entity1 with normal baseline resting wall motion. METHODS: We enrolled 70 consecutive @entity1 with no resting @entity854 ( @entity854 ) who underwent DSE. DSE was repeated with pneumatic compression of the lower extremities 3 days after the initial standard DSE. Positive test was defined as the induction of @entity854 in at least 2 contiguous non-overlap segments at any stage of @entity452 infusion. Significant @entity3979 was defined as >= 50% obstruction of >= 1 sizable artery by coronary angiography. : RESULTS: The mean age of the study cohort was 54.7    9.9 years; 55.7% were females. Thirty-eight @entity1 (54.3%) had significant @entity453 . The mean test duration was 15.8    5.1 minutes for standard DSE and 11.7    4.1 minutes for DSE with pneumatic compression. Analysis of standard DSE revealed sensitivity, specificity, positive and negative predictive values of 81.6%, 90.6%, 91.2%, 80.6%; overall accuracy was 85.7%. Analysis of DSE with pneumatic compression revealed sensitivity, specificity, positive and negative predictive values of 89.5%, 87.5%, 89.5%, 87.5%; overall accuracy was 88.6%. CONCLUSIONS: In symptomatic @entity1 with suspected @entity453 referred for evaluation by DSE who have no resting @entity854 , pneumatic compression of the lower extremities during DSE improved the sensitivity but slightly reduced the specificity for detection of angiographically significant @entity453 compared with standard DSE. Moreover, it reduced the test duration.
