Low negative predictive value of dobutamine stress echocardiography before abdominal aortic surgery.
BACKGROUND According to previous studies, a negative dobutamine stress echocardiography (DSE) test before major vascular surgery indicates that postoperative myocardial necrosis is very unlikely. We believe that the use of new cardiac troponin assays which can detect small amounts of myocardial necrosis results in a lower DSE negative predictive value for myocardial necrosis. METHODS A total ...
متن کاملDobutamine stress echocardiography in patients with low-gradient aortic stenosis.
In adults with moderate or severe aortic stenosis (AS), valve replacement surgery is recommended when symptoms (ie, angina, syncope, or congestive heart failure) appear.1 In such patients, valve replacement surgery alleviates symptoms and improves survival, even in those with a depressed left ventricular ejection fraction (LVEF). Although a minority of patients with symptomatic AS have a reduce...
متن کاملPredictive Value of Dobutamine Stress Perfusion Echocardiography in Contemporary End‐Stage Liver Disease
BACKGROUND The assessment of cardiac risk in contemporary liver transplantation (LT) has required more sensitive testing for the detection of occult coronary artery disease as well as microvascular and functional cardiac abnormalities. Because dobutamine stress perfusion echocardiography provides an assessment of both regional systolic and diastolic function as well as microvascular perfusion (...
متن کاملPrognostic value of low-dose dobutamine stress echocardiography in patients with aortic stenosis and impaired left ventricular function
INTRODUCTION The aim of this multicenter, prospective study was to evaluate the long-term prognostic value of low-dose dobutamine stress echocardiography (LDDSE) in patients with aortic stenosis (AS) and depressed left ventricular (LV) function. MATERIAL AND METHODS The study group comprised 39 patients (34 male, mean age 59 ±13 years) with AS (peak gradient > 25 mm Hg), LV ejection fraction ...
متن کاملDobutamine 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...
