AIMS Recent studies have evaluated the diagnostic accuracy and predictive value of dobutamine echocardiography without considering the additional information implied by the magnitude of induced wall motion abnormalities. We sought to evaluate the positive predictive value of dobutamine echocardiography for coronary artery disease from the extent and severity of the induced wall motion abnormali...

BACKGROUND The use of parenteral positive inotropic agents still remains a major component of therapy for patients with advanced decompensated congestive heart failure (CHF). However, no consensus guidelines have been developed for the appropriate selection of a first-line inotropic therapy. We sought to compare the clinical outcome and economic cost of dobutamine-based and milrinone-based ther...

This study aimed to determine cardioyascular involvement in mild hyaline membrane disease (HMD) and its resPonse to dobutamine administration. The study was done at Dr. Cipto Mangunkusumo Hospital, Jakarta, from November 1997 to May 1998. Study subjects were preterm infants withmildHMDwith thebirthweight of >1250 grams, andagedless than48 hours. All measurements were done by using non-inyasive ...

We infused dobutamine (20 microgram/kg per min) intravenously, once before and once after coronary artery occlusion, in 10 chronically instrumented dogs. Both infusions increased cardiac output and left ventricular dP/dt and dP/dt/P, but divergent effects on heart rate and aortic blood pressure were observed. Dobutamine decreased heart rate and increased mean aortic blood pressure before corona...

BACKGROUND The conventional dobutamine protocol for the investigation of induced myocardial ischemia is well established. Our objective was to evaluate the effects of early administration of atropine during the dobutamine stress echocardiogram, as compared to its conventional use. METHODS One hundred and twenty-one patients were referred to the dobutamine stress echocardiogram, for the invest...

AIMS The patho-physiology of apical ballooning syndrome (ABS) has not been clearly defined. The aim of this study was to determine whether patients with a history of ABS are more likely to develop left ventricular (LV) mid-cavity or outflow tract obstruction, or have a greater regional LV contractile response to an adrenergic stimulus compared with normal controls. METHODS AND RESULTS Twenty ...

OBJECTIVE To determine whether, compared with fundamental imaging, second harmonic imaging can improve the accuracy of dobutamine stress echocardiography for identifying viable myocardium, using nuclear imaging as a reference. PATIENTS 30 patients with chronic left ventricular dysfunction (mean (SD) age, 60 (8) years; 22 men). METHODS Dobutamine stress echocardiography was carried out in al...

Fifteen patients with congestive cardiomyopathy (six idiopathic and nine alcoholic) manifested by heart failure (New York Heart Association class III or IV) were randomly assigned to a protocol in which dobutamine (n = 8) or 5% dextrose in water (n = 7) was infused continuously for 72 hr. The dose of dobutamine was titrated to increase cardiac output to twice the baseline values. The patients w...
