OBJECTIVES The aim of this study was to investigate the effects of gender on long-term prognosis of patients undergoing dobutamine stress echocardiography (DSE). BACKGROUND Gender differences in the predictors of outcome among patients with known or suspected coronary artery disease undergoing DSE have not been adequately studied. METHODS We studied 2,276 men and 1,105 women with known or s...

System-level design space exploration (DSE), which is performed early in the design process, is of eminent importance to the design of complex multi-processor embedded multimedia systems. During system-level DSE, system parameters like, e.g., the number and type of processors, and the mapping of application tasks to architectural resources, are considered. The number of design instances that ne...

The prognostic value of dobutamine stress echocardiography (DSE) at >10-year follow-up is unknown. The aim of this study was to assess the very long-term prognostic value of DSE in a high-risk cohort of patients with known or suspected coronary artery disease. This prospective, single-center study included 3,381 patients who underwent DSE from January 1990 to January 2003. Two-dimensional echoc...

Decision systems play an ever increasing role in today's enterprises. The design of these specific information systems requires much expertise. The maturity of methodologies for guiding the designers is not sufficient, leading to systems requiring costly maintenance. Therefore, the purpose of this first International Workshop on Decision Systems Engineering (DSE'03) is to enable participants to...

BACKGROUND Diastolic dysfunction precedes systolic dysfunction in patients with coronary artery disease. The aim of the study was to evaluate the effects of left ventricular (LV) wall motion abnormality (WMA) on diastolic LV and right ventricular (RV) function at rest and after stress. METHODS Fifty-nine subjects, 15 with LV-WMA (abnormal group) and 44 without (normal group), underwent dobuta...

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...

Dynamic state estimation (DSE) accurately tracks the dynamics of a power system and provides evolution in real-time. This paper focuses on control protection applications DSE, comprehensively presenting different facets challenges arising modern systems. It is demonstrated how these are effectively addressed with DSE-enabled solutions. As precursors to solutions, reformulation DSE considering b...

Recently there has been an upsurge of interest in both, Search– Based Software Testing (SBST), and Dynamic Symbolic Execution (DSE). Each of these two approaches has complementary strengths and weaknesses, making it a natural choice to explore the degree to which the strengths of one can be exploited to offset the weakness of the other. This paper introduces an augmented version of DSE that use...

BACKGROUND Longitudinal systolic left ventricular contraction is complementary to the radial performance and can be assessed using tissue Doppler imaging (TDI). This study was performed to evaluate the contribution of mitral annular systolic velocities using TDI after dobutamine stress echocardiography (DSE). METHODS AND RESULTS Fifty subjects with suspected coronary artery disease and chest ...

BACKGROUND Although dobutamine stress echocardiography (DSE) is performed in heart transplant patients, the safety profile of atropine administration in DSE in this setting is unclear. METHODS AND RESULTS We identified heart transplant patients who received atropine during DSE from January 1984 to August 2011 at our institution and compared them with a propensity-scored matched control group ...
