Refinements in stress echocardiographic techniques improve inter-institutional agreement in interpretation of dobutamine stress echocardiograms.
AIMS To determine the degree of inter-institutional agreement in the assessment of dobutamine stress echocardiograms using modern stress echocardiographic technology in combination with standardized data acquisition and assessment criteria. METHOD AND RESULTS Among six experienced institutions, 150 dobutamine stress echocardiograms (dobutamine up to 40 microg x kg(-1) min(-1) and atropine up ...
متن کاملA step further in inter-institutional agreement in interpretation of dobutamine stress echocardiograms.
methods may be employed. In general, several studies, including the one from Blanc and co-workers, have clearly shown that effective care delivery can be difficult, while a significant percentage of patients with syncope are still discharged from hospital without a diagnosis. Consequently, a cost-effective management of syncope should rely upon the implementation of specific clinical guidelines...
متن کاملLeft ventricular outflow tract and mid-cavity obstruction may cause false-positive dobutamine stress echocardiograms.
Left ventricular (LV) outflow tract obstruction (LVOTO) occurs in up to 20% of patients undergoing dobutamine stress echocardiography (DSE). Mid-cavity LV obstruction occurs less commonly during DSE. LV regional wall motion abnormalities during DSE may occur despite normal coronaries due to hypertensive blood pressure response and takotsubo stress cardiomyopathy. We describe herein two cases of...
متن کاملCoronary Artery Spasm During Dobutamine Stress Echocardiography: A Case Report
Dobutamine stress echocardiography (DSE) has been widely used as a diagnostic and prognostic modality in the management of stress. DSE is associated with limited complications and adverse effects on the health of patients. In this case report, we described a 42-year-old female patient with dobutamine-induced coronary artery spasm with history of exertional dyspnea, which had deteriorated recent...
متن کاملDobutamine stress testing revisited.
I read with great interest the recently published study by Calnon et al. (1), which analyzed the clinical outcome of patients who underwent dobutamine stress single-photon emission computed tomography (SPECT) Tc-99m-sestamibi imaging. Two aspects of this study are rather intriguing, and deserve further examination. First, the annual “hard” cardiac event rate in patients with normal dobutamine S...
