Comparison With Dobutamine
Background. We hypothesized that the effect of pimobendan (UD-CG 115 BS) to increase calcium sensitivity of contractile protein might result in less myocardial oxygen consumption (Vo2) in comparison with dobutamine when they enhance ventricular contractility to the same extent. To examine this hypothesis, we compared the effects of pimobendan and dobutamine on left ventricular contractility and...
متن کاملDobutamine stress echocardiography.
Two-dimensional echocardiography is a versatile, accurate, and readily available method for the assessment of cardiac anatomy and function, and extensive experience has been gained in the analysis of left ventricular wall motion. Using modern imaging techniques, regional as well as global wall motion analysis can be performed. Echocardiography can be used in conjunction with a protocol for eith...
متن کاملDobutamine stress testing revisited.
I read with great interest the recently published study by Calnon et al. (1), which analyzed the clinical outcome of patients who underwent dobutamine stress single-photon emission computed tomography (SPECT) Tc-99m-sestamibi imaging. Two aspects of this study are rather intriguing, and deserve further examination. First, the annual “hard” cardiac event rate in patients with normal dobutamine S...
متن کاملDobutamine-Induced Mechanical Alternans
We investigated the relationship between the occurrence of dobutamine-induced mechanical alternans (MA) and prognosis in ambulatory patients with idiopathic dilated cardiomyopathy (IDCM). Recent American College of Cardiology and American Heart Association guidelines for the management of heart failure have emphasized the need for earlier identification and therapy for patients at high risk of ...
متن کاملCoronary Artery Spasm During Dobutamine Stress Echocardiography: A Case Report
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...
