Pharmacological vs Exercise Stress Echocardiography for Detection of Cardiac Allograft Vasculopathy

Mayo Clinic Proceedings: Innovations, Quality & Outcomes, 2020
Objective: To test the hypothesis that exercise and dobutamine would provide levels of cardiac stress that are comparable to those achieved in a general stress test population, and to one another, in heart transplant recipients.

Myocardial work index during normal dobutamine stress echocardiography

Scientific Reports, 2022
Dobutamine stress echocardiography is an alternative method to exercise stress echocardiography for the evaluation of ischemia. Recently, the novel speckle tracking imaging derived parameter, myocardial work index, was suggested for the evaluation of ...

Predictive significance of residual ischemia proved by dobutamine stress: Echocardiography test in patients early after the first uncomplicated myocardial infarction [PDF]

Vojnosanitetski Pregled, 2004
Background. To evaluate the long-term prognostic value of dobutamine stress-echocardiography (ECG) test for new coronary events (new episodes of angina pectoris, cardiac-related deaths, and reinfarctions) early after the first uncomplicated myocardial ...

Effect of Supplemental Oxygen versus Dobutamine Administration on Liver Oxygen Tension in dPP-Guided Normovolemic Pigs [PDF]

, 2009
Background: Difference in pulse pressure (dPP) confirms adequate intravascular filling as a prerequisite for tissue perfusion. We hypothesized that both oxygen and dobutamine increase liver tissue oxygen tension (ptO(2)). Methods: Eight anesthetized pigs

Clinical pharmacology of dobutamine and dopamine in preterm neonates [PDF]

, 2014
Dobutamine is a β1 selective stimulant. β Receptor agonists are used to stimulate the rate and the force of cardiac contraction. The chronotropic effect is useful for the treatment of arrhythmias whereas the inotropic effect is useful to augment the ...

The effects on arterial haemoglobin oxygen saturation and on shunt of increasing cardiac output with dopamine or dobutamine during one-lung ventilation

, 2004
Publisher's copy made available with the permission of the publisher © Australian Society of AnaesthetistsTheoretically, if the cardiac output were increased in the presence of a given intrapulmonary shunt, the arterial saturation should improve as the ...

Right Ventricular Asynergy During Dobutamine-Atropine Echocardiography

, 1997
Objectives. We sought to analyze right ventricular contractility during dobutamine infusion in patients with right coronary artery disease and to elucidate whether the development of right ventricular asynergy aids in characterizing a right coronary ...

Effects of Intravenous Dobutamine on Coronary Vasomotion in Humans [PDF]

, 2003
OBJECTIVES: We sought to investigate the vascular mechanisms of dobutamine-induced myocardial ischemia. BACKGROUND: Dobutamine stress is often used as a surrogate for exercise.

Dobutamine-induced strain and strain rate predict viability following fibrinolytic therapy in patients with ST-elevation myocardial infarction

Frontiers in Cardiovascular Medicine, 2015
Background: Low-dose dobutamine stress echocardiography is increasingly used for identifying myocardial viability.Aim: We explored whether dobutamine-induced strain (S) and strain rate (SR) can identify myocardial viability following fibrinolytic therapy

Enoximone echocardiography: a novel test to evaluate left ventricular contractile reserve in patients with heart failure on chronic beta-blocker therapy

Cardiovascular Ultrasound, 2003
Background It has been suggested that an extensive contractile reserve identified recognised by means of dobutamine stress echocardiography may predict a better prognosis in patients with severe left ventricular dysfunction at rest. However, the clinical
