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 dobutamine stress echocardiography (DSE) with pneumatic compression of the lower extremities, vs. standard DSE, for detection of angiographically significant coronary artery disease (CAD) in patients with normal baseli...

BACKGROUND Dobutamine stress echocardiography (DSE) is an accepted test for the diagnosis of coronary artery disease (CAD), despite its wide diagnostic accuracy. AIM Which factors cause test variability of DSE for the diagnosis of CAD. METHODS In a retrospective analysis of 46 studies in 5,353 patients, the potential causes of diagnostic variability were systematically analyzed, including p...

background: this study was designed to investigate the accuracy of dobutamine stress echocardiography (dse) in detecting the post-revascularization recovery rate of contractile reserve (cr) in ischemic myocardium. methods: a total of 112 segments from seven patients with low ejection fraction (<35%) and coronary artery disease were evaluated with dse one week before and 12 weeks after coronary ...

AIMS Although two-dimensional-dobutamine stress echocardiography (2D-DSE) is useful for the diagnosis of myocardial ischaemia, it requires the acquisition of multiple cross-sections at each stage. The introduction of new real-time three-dimensional echocardiography (RT3DE) offers rapid acquisition and 3D display of the entire left ventricle (LV). The purpose was to evaluate real-time three-dime...

BACKGROUND Stress echocardiography is an important diagnostic and prognostic tool in ischemic heart disease. OBJECTIVE To evaluate the role of dipyridamole stress echocardiography (DSE) in the investigation of myocardial ischemia in women and its ability to predict combined events (cardiovascular death, acute myocardial infarction [AMI], unstable angina, coronary artery bypass grafting [surge...

INTRODUCTION Although global deformation parameters have been increasingly used for myocardial function analysis, there are sparse data concerning segmental deformation of the left ventricle (LV). Moreover, some studies suggest heterogeneity of strain among LV segments, which may be especially significant during stress echocardiography. We assessed quantitatively regional LV function in the set...

results administration of dse significantly increased serum paraoxonase and arylesterase activities in treated hypercholesterolemic groups compared to untreated ones. there was a significant difference in the taoc of serum between the normal diet and hypercholesterolemic groups. however, dse did not change the taoc in hypercholesterolemic groups significantly. conclusions dse increases serum pa...

Although dobutamine stress echocardiography (DSE) is a well-defined tool for the diagnosis of coronary artery disease (CAD), false-negative and false-positive results still occur. This study investigated the diagnostic role of layer-specific analysis using 2-dimensional speckle-tracking echocardiography (STE) during DSE.A total of 121 patients who underwent DSE and showed normal wall motion and...

BACKGROUND Afterload is expected to increase with pneumatic compression of the lower extremities. There are left ventricular (LV) wall stress, which is the most important factor determining myocardial oxygen demand, will also increase, leading to an increase in the sensitivity of dobutamine stress echocardiography (DSE) or a shortened time to a positive response. METHODS AND RESULTS In 40 pat...

BACKGROUND Dobutamine stress echocardiography (DSE) is used for risk stratification of patients with suspected coronary artery disease (CAD). However, the prognostic value of DSE among the entire strata of renal function has yet to be determined. We assessed the prognostic value of renal function relative to DSE findings. METHODS We studied 2292 patients, divided into 729 (32%) patients with ...
