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...

AIMS Dobutamine stress echocardiography (DSE) is widely used to evaluate myocardial contractile reserve in patients with heart failure (HF). The aim of the study was to assess the relationship between the tissue Doppler (TD) mitral annulus systolic velocity (Sm) change during DSE, contractile reserve, and aerobic exercise capacity in HF patients. METHODS AND RESULTS Sixty-four HF patients (ag...

OBJECTIVES The aim of the study was to assess the prognostic value of myocardial viability and ischemia detected by dobutamine stress echocardiography (DSE) in patients with acute myocardial infarction (AMI) treated with thrombolysis. BACKGROUND DSE can detect myocardial viability and ischemia early after AMI, but the prognostic importance of viability and ischemia in these patients has yet t...

With the rise of digital transformation in all domains, relationship between digitalization and sustainable entrepreneurship has received growing attention. In practice, a new entrepreneurial model called “digital entrepreneurship” (DSE) emerged. Aiming to establish DSE based on capability (DC) innovation orientation (DIO), this study explored what kind could be built lead boost entrepreneurshi...

BACKGROUND The purpose of this study was to assess the long-term value of dobutamine-atropine stress echocardiography (DSE) for prediction of late cardiac events in patients with proven or suspected coronary artery disease. METHODS AND RESULTS Clinical data and DSE results were analyzed in 1734 consecutive patients undergoing DSE between 1989 and 1997. Seventy-four patients who underwent reva...

Hyperbaric oxygen treatment (HBO) could transiently reverse hypoxia during acute myocardial infarction (AMI). In order to evaluate whether early HBO can identify viable segments after AMI, improvement of wall motion score index (WMSI) after HBO was compared to dobutamine stress echocardiography (DSE). Thirty-one patients with first AMI treated with thrombolysis received 100% oxygen at 2 technic...

Delonix elata L. (Ceasalpinaceae), is widely used by the traditional medical practitioners of Karnataka, India, to cure jaundice, and bronchial and rheumatic problems. The objective of this study was to screen the in vitro antioxidant and hepatoprotective activity of the stem bark extracts against CCl4-induced liver damage in rats. Among different stem bark extracts tested, the ethanol extract ...

Software deobfuscation is a crucial activity in security analysis and especially, in malware analysis. While standard static and dynamic approaches suffer from well-known shortcomings, Dynamic Symbolic Execution (DSE) has recently been proposed has an interesting alternative, more robust than static analysis and more complete than dynamic analysis. Yet, DSE addresses certain kinds of questions ...

Gram-negative pathogens commonly use the chaperone-usher pathway to assemble adhesive multisubunit fibers on their surface. In the periplasm, subunits are stabilized by a chaperone that donates a beta strand to complement the subunits' truncated immunoglobulin-like fold. Pilus assembly proceeds through a "donor-strand exchange" (DSE) mechanism whereby this complementary beta strand is replaced ...

Dobutamine stress echocardiography (DSE) is an effective modality for determining the presence of myocardial ischemia from obstructive coronary artery disease (CAD) [1]. Several large studies have deemed DSE a largely safe imaging tool, with minimal side effects [2-5]. The most serious and rare side effects being sustained ventricular tachycardia, intracranial hemorrhage, and myocardial infarct...
