To define the role of the assessment of myocardial viability with dobutamine echocardiography (DE) in the clinical evaluation and selection of the best treatment for a high-risk subset of patients with coronary artery disease.
Low systemic flow as measured by Doppler-echocardiography has been associated with poor neurological outcome. Yet, it has not been systematically evaluated whether the treatment of this hemodynamic condition is beneficial or not. This study aims to evaluate if treating low systemic flow in preterm infants with dobutamine has any effect on the cerebral circulation and in newborn prognosis.
Survival of Patients With Acute Heart Failure in Need of Intravenous Inotropic Support: a Multicentre, Parallel-Group, Randomised, Double-Blind, Double-Dummy Study of Levosimendan Versus Dobutamine in Patients With Acute Heart Failure.
The primary objective of the study is to compare the efficacy of levosimendan and dobutamine on all-cause mortality in the 180 days following randomization.
Recent studies have suggested that the use of left ventricular ejection volume index calculation may aid in the hemodynamic management of critically ill patients. However, a prospective and randomized comparison in patients with heart failure for inotropic dose adjustment has not been described. The objective of this study was to evaluate the efficacy and safety of ejection volume index versus liberal strategy in adjusting dobutamine dose in patients with heart failure and low ...
This is a randomized, double blind, single center trial to study of the effects of Ivabradine vs. Placebo on patients hospitalized for Stage D heart failure (HF)/ and cardiogenic shock (CS) who will require continuous infusion of Dobutamine and have developed sinus tachycardia (ST) (heart rate >100 beats/min). The aim of the study will be to assess the potential of Ivabradine to slow ST and improve hemodynamics in patients with stage D HF/CS on Dobutamine treatment.
To assess the effect of hemodynamic supportive medication on spinal vasculature, patients scheduled for arterial dilation of the lower limb were chosen as our study population. The spinal cord perfusion is not compromised in these patients, however, most patients suffer from hypotension during this kind of surgery, due to the non-invasive type of surgery and the vasodilating effects of the anesthetics. Therefore, continuous administration of vasoactive medication (phenylephrine...
Patients with poor heart function can, in certain situations, have a further weakening of the heart muscle such that it becomes difficult to provide enough blood to the brain and other organs. In these cases, heart function can be supported by the use of medicines or heart pumps. One of the most widely used medicines is Dobutamine, given as an infusion (a drip). Although Dobutamine has been in use for decades and does improve blood flow to the organs, previous studies have not ...
Primary purpose :To early detect cardiac allograft vasculopathy and to identify patients with high risk of cardiac events, by coupling the analysis of the kinetics of the brain natriuretic peptide ( BNP) with that of the left ventricle (LV) during a dobutamine stress echocardiography. Hypothesis : Plasma BNP elevation and abnormalities of LV kinetic during the ESD, will be associated with the presence of allograft vasculopathy and the arisen of cardiovascular events.
The purposes of this study in United Network for Organ Sharing (UNOS) Status 1B (or country equivalent) cardiac transplant candidates are to assess the safety and efficacy of nesiritide. The study will evaluate the drug's ability to prevent clinical worsening when administered as a 28-day continuous intravenous infusion in patients receiving standard care and continuous intravenous infusion of dobutamine or milrinone.
This study will determine whether an acute infusion of intravenous allopurinol improves the inotropic response to dobutamine in patients with idiopathic dilated cardiomyopathy (DCM) as measured by cardiac magnetic resonance imaging (CMR).
Examine the clinical utility of the dobutamine stress contrast echoes and angiograms obtained routinely in the evaluation of patients prior to kidney or pancreas transplantation.
Patients with cirrhosis have a altered cardiac response to stress. This study evaluate the cardiac response by MRI during dobutamine stress. Hypothesis: impared increase in cardiac output, cardiac index, ejection fraction.
The purpose of the study is to verify the ability of the HyperQ signal to detect Dobutamine induced Ischemia. The gold standard for ischemia will be the results of Angiography if performed, or Echocardiographic imaging, which was performed during the test.
Cardiogenic shock is a frequent cause of admission and death in the intensive care unit. Mortality is about 50%. Once the etiologic treatment has been done, for instance coronary revascularization, management of the shock state is the cornerstone of the treatment. Norepinephrine is the first-line vasopressor therapy because of its minor effect on heart rhythm. Morever norepinephrine is a inotrope. In a previous study, we demonstrated that increasing the norepinephrine dose inc...
While cardiac resynchronization therapy (CRT) has a well demonstrated therapeutic effect in selected patients with advanced heart failure (HF) on optimized drug therapy, non-responder rate remains high. The low-dose dobutamine stress-echo (DSE) test to predict positive response to CRT (LODO-CRT) trial is designed to improve patient selection for CRT.
The heart becoming "stiff" due to increased fibrous tissue or decreased elasticity of the heart tissue is one of the earliest changes caused by heart failure. These changes can be detected by simple non-invasive echocardiogram techniques. However, these techniques usually detect the increased "stiffness" of the heart only after it has progressed to a significant extent. The investigators hypothesize that if they stress the heart using a Dobutamine infusion and measure the filli...
The purpose of this study is to compare the effects on heart rate and ventricular arrhythmias (irregular heart beats) of two doses of NatrecorÂ® (a recombinant form of the natural human peptide normally secreted by the heart in response to heart failure) versus dobutamine, during the first 24 hours of treatment of decompensated congestive heart failure (CHF).
Left myocardial infarction (MI), has a negative impact of long term morbidity and mortality. Even in patients treated successfully by angioplasty in the acute phase of infarct, the remodelling is observed in approximately 30% of cases. It is important to predict the occurrence of this phenomenon in the early phase after MI for the selection of patients who could eventually benefit from new therapeutic approach as for example cell replacement therapy. It has been advocated that ...
The investigators are interested in determining if there is a meaningful difference between two of the most commonly used medications used to improve the pumping function of the heart among critically ill patients admitted to the Coronary Care Unit (CCU) at the University of Ottawa Heart Institute (UOHI). To do this, the investigators will randomly assign patients who are felt to require use of these medications by their treating physicians to one of the two most commonly used ...
The purpose of this study is to determine whether neuromuscular electrical stimulation can improve exercise tolerance for patients with heart failure and continuous dobutamine use in a hospital.
The present study is designed to: 1. investigate the safety and efficacy of Real time myocardial echocardiography (RT-MCE) in adolescents and adults ages 13-40 with congenital and acquired congenital heart disease 2. compare RT-MCE with dobutamine stress perfusion MR for determination of coronary flow reserve and ventricular wall motion 3. assess regional myocardial mechanics using myocardial speckle tracking and MR tagging.
Haemodynamic insufficiency after birth is seen commonly in babies born prematurely and is associated with adverse outcomes. In current clinical practice, a combination of blood pressure and clinical signs is used to guide therapy. However, blood pressure is a poor surrogate of systemic and organ (brain) blood flow distribution during transitional circulation. This state is characterised by increased peripheral vascular resistance and increased afterload causing myocardial depre...
This study investigates hypothesizes that the combination of dobutamine stress echocardiography with dobutamine stress echocardiography with real time perfusion myocardial contrast echocardiography and coronary computed tomography is a better modality for detecting coronary artery disease in end-stage renal disease patients than coronary angiography, and in predicting patient outcomes. Demonstrating this would lead to increased use of DSE with RTCE and coronary CT at kidney tr...
