In contrast, Severi et al. 42 ; observed dobutamine-induced wall motion abnormalities in association with a blunted increase in regional myocardial flow. Thus, the effects of dobutamine on regional function are variable and may be dependent on hemodynamic as well as metabolic parameters.
Health and Human Services 1983 ; and the Na tionwide Food Consumption Survey USDA 1984 ; . Energy estimates reported here have also been com pared with estimates derived from four 2-d food records in a subsample of this Beaver Dam population unpublished data ; . In men, estimates derived from this questionnaire were 10 and 3% higher than esti mates from food records in persons 43-64 and 65-84 y of age, respectively. In women, diet questionnaire estimates were 10 and 15% lower than food record estimates in the middle- and older-aged groups, respectively. Thus, in women but not men, energy intake means are likely to be underestimated using.
Regional asynchrony and not solely by esmololinduced RWMA. LV contraction is normally heterogeneous 19 ; . Although we compared regional volumes and ESPVR along the LV longitudinal axis, this regional separation is neither anatomically correct nor reflective of the distribution of the induced RWMA. Specifically, esmolol-induced RWMA affected only a portion of the apical and chordal regions with some myocardium in both regions unaffected, as demonstrated by the crystal violet dye distribution. Finally, in support of our method of analysis, systemic dobutamine infusion affected all regions, whereas intracoronary esmolol infusion only affected apical regions. We previously confirmed the accuracy of relative conductance volumes in our laboratory 17 ; , as verified by others both in vivo and in vitro 20, 21 ; . Thus, it is unlikely that observed parallel shifts of the LV ESPVR reflect treatment-specific parallel conduction artifacts.

Mid-ventricular systolic gradient MSG - peak systolic velocity 2m s ; have been reported as a consequence of the inotropic effect of dobutamine mainly in pts with negative tests. However the influence of LV size and shape has not been studied yet. We therefore hypothesized that MSG is primarily dependent on LV geometry. Methods: 118 pts with normal standard high-dose ; DSE were included in this study divided into 2 groups according to the presence of MSG. Group A with ; : 19 pts, 13 female, 56.29.6 years and Group B without ; : 99 pts, 60 female, 61.812.2 years. For both groups LV wall thickness WT ; , diameters D ; , volumes and ejection fraction were obtained. Geometry was defined as the diastolic WT D ratio. Results: MSG was observed in 19 118 pts 16% ; . There were no statistical differences for gender distribution p 0.701 ; and age p 0.059 ; . Table shows the results for LV parameters.

The present study demonstrates significant differences in outcome, particularly for in-hospital mortality, based on the choice of IV vasoactive medication used in the treatment of ADHF. Specifically, the present analysis contributes to our fund of knowledge by showing that mortality is similar with the natriuretic peptide nesiritide and the vasodilator nitroglycerin but significantly higher with the use of the positive inotropic agents dobutamine and milrinone. This observation may have significant implications for IV drug selection in the management of such patients, suggesting that natriuretic peptides and vasodilators should be preferred over positive inotropic agents in patients with ADHF requiring treatment with an IV vasoactive drug. Each of these IV vasoactive agents is commonly used to treat ADHF patients, and each has a unique mechanism of action and risk benefit profile 1719 ; . Dobutamine is a direct-acting positive inotropic agent with primary activity resulting from the stimulation of beta-adrenergic receptors in the heart 17 ; . Milrinone, a cyclic adenosine monophosphate-specific phosphodiesterase inhibitor, produces positive inotropic and vasodilatory effects independent of beta-adrenergic receptor stimulation but acts in the heart via the same signal-transduction pathway as dobutamine 18, 19 ; . Nitroglycerin reduces preload and afterload by dilating peripheral capacitance and resistance vessels through a direct interaction with receptors.

And a transit-time flow probe 3 mm RS with coronary flange, Transonic Systems Inc ; was implanted on the left circumflex coronary artery. After 2 weeks of recovery, transit-time flow probes were implanted on the cranial mesenteric artery 6 mm RS ; , left renal artery 4 mm RS ; , and external iliac artery 6 mm RS ; one sheep a transit-time flow probe 6 mm RS ; was placed on the celiac artery; in this animal coronary flow was not measured. The transit-time flow probes were connected to a Transonic T201CDS flowmeter via a four-channel sequential scanner TM04, Transonic Systems ; , and the electromagnetic flow probes were activated by a flowmeter Biotronex ; . The output voltage of the electromagnetic flowmeter was reset to zero, using an autozero circuit, during a portion of each diastole when blood flow in the ascending aorta is assumed to be zero. A month after implantation, the electromagnetic flow probes were calibrated in vivo against thermodilution over a range of CO values. Dobutamine Dobutrex, Eli Lilly & Co ; was used to increase CO from approximately 4 to 9 min. Blood pressure was measured via an indwelling Tygon cannula 0.1-mm inner diameter, 1.5-mm outer diameter ; inserted 15 cm into a carotid artery. The cannula was connected to a pressure transducer TDXIII, Cobe ; tied to the wool on the sheep's back, and the pressure was corrected to compensate for the height of the transducer above heart level. The transducer was calibrated daily against a mercury manometer. Central venous pressure CVP ; was measured via a polyethylene cannula 1.18-mm inner diameter, 1.7-mm outer diameter ; inserted 25 cm into a jugular vein connected to a pressure transducer TDXIII, Cobe ; and recorded on a chart recorder RS 3400, Gould ; . CVP was measured between 9 and 10: 30 every morning for 15 minutes, with the sheep standing quietly with their heads in a neutral position. The transducer was positioned at heart level and was calibrated against a water manometer. Analog signals blood pressure, CO, and regional flows ; were collected using a PC 486 data-acquisition system with custom-written software. Data were collected at 100 Hz for 10 seconds at 10-minute intervals. Individual data points were pooled into 24-hour means for day-to-day comparisons. In addition, data for the first 24 hours of ACTH and saline infusions were pooled into 1-hour blocks for assessment of the onset of the hemodynamic effects of ACTH.

| Dopamine dobutamine noradrenalineFrom baseline akinesia to dyskinesia developed during the test. This finding is in keeping with the results of Arnese1251 and probably reflects the passive systolic bulging of the necrotic segments that may generate stress-induced ST-segment elevation14'51. We found a significant positive correlation between the degree of ST-segment elevation and the asynergy score index both at baseline and at peak stress. On the other hand no significant correlation was found between Delta ST and the difference between stress and baseline asynergy score index that reflects the extent of peri-infarction ischaemia. Also, other authors'22' recently found a significant correlation between STelevation and thallium defect score both at rest and during stress in a group of 88 patients with recent myocardial infarction undergoing dobutamine stress test; in this study stress-induced ST-segment elevation was associated with a smaller increase in regional ejection fraction, reflecting a more severe asynergy of necrotic segments. In our study myocardial viability and ischaemia in the infarct area were detected in a similar percentage of patients in the two groups. The incidence of ischaemic wall motion abnormalities in our patients with STsegment elevation was similar to that of peri-infarct redistribution at thallium scintigraphy 74 vs 72% ; found by Coma-Canella in a comparable group of patients. Among the 23 patients with ST-segment elevation, six had no evidence of reversible asynergy in the infarcted zone and 17 showed reversible wall motion abnormalities indicative of peri-infarction ischaemia. Of the 17 patients with reversible asynergy, six patients had 50% and 11 2: 50% of basally asynergic segments showing peri-infarction ischaemia. These findings suggest that in patients with recent myocardial infarction dobutamine-induced ST-segment elevation may be associated both with irreversible and reversible ischaemia-induced wall motion abnormalities in the peri-infarction area and cannot be considered a specific marker of myocardial ischaemia. A possible limitation of the study is that 47% of the patients were treated with anti-anginal drugs.
