Dobutamine stress echocardiography.
Two-dimensional echocardiography is a versatile, accurate, and readily available method for the assessment of cardiac anatomy and function, and extensive experience has been gained in the analysis of left ventricular wall motion. Using modern imaging techniques, regional as well as global wall motion analysis can be performed. Echocardiography can be used in conjunction with a protocol for eith...
متن کاملHypotension and dobutamine stress echocardiography.
morning at 7:00 AM by a group of cardiologists, radiologists, and vascular surgeons, at which time treatment recommendations are made by consensus. The same meeting is used to review successes, failures, and complications resulting from the proposed treatments. It is our strong feeling that such mutual cooperation-and respect-ultimately works to the best interest of the patient. Such a forum, i...
متن کاملFalse Positive Dobutamine Stress Echocardiography Induced by Esmolol
Dear Editor, Dobutamine stress echocardiography is one of the several noninvasive methods for detection of coronary artery disease (1). New regional wall motion abnormalities have been reported in dobutamine stress echocardiograpghy after intravenous beta blocker administration (2, 3) Thus, this method has been recommended for increasing the test sensitivity (4). The sensitivity, specificity, a...
متن کاملLow dose dobutamine stress echocardiography predicts the improvement of left ventricular systolic function in dilated cardiomyopathy.
OBJECTIVE To determine whether dobutamine stress echocardiography can predict the improvement of left ventricular systolic function in patients with dilated cardiomyopathy (DCM). METHODS Myocardial contractile reserve, as assessed by dobutamine stress echocardiography, was determined in 18 patients with DCM (mean (SD) age 53 (13) years, left ventricular ejection fraction (LVEF) 28 (10)%) and ...
متن کاملQuantification of low-dose dobutamine stress using speckle tracking echocardiography in coronary artery disease.
AIMS We sought to evaluate the utility of speckle tracking echocardiography (STE) for detecting left ventricular (LV) mechanical abnormalities during low-dose (20 microg) dobutamine stress (DSE). METHODS AND RESULTS Twenty-nine patients (56 +/- 12 years) with a history of recent acute coronary events (ACE) underwent STE-DSE. Left ventricular images, sampled at frame rates 70-100 Hz, were anal...
