Because it is not known where in the reflex arch, i.e., afference, central nervous system or efferences, hyperglycemia affects baroreflex function, the present study examined the effect of short-term (30 min) hyperglycemia on aortic depressor nerve function measured by a mean arterial pressure vs aortic depressor nerve activity curve, fitted by sigmoidal regression, or by cross-spectral analysi...
Incidence and prognostic relevance of supraventricular arrhythmias were evaluated in nine studies. These studies investigated patients with different forms of pulmonary hypertension. Supraventricular arrhythmias were more often found in patients with group two pulmonary hypertension. Common findings in these patients were elevated right atrial pressure and diameters and reduced tricuspid annula...
The aim of our study was to assess whether the Finapres device is able to accurately monitor not only average blood pressure values but also blood pressure variability. To examine this issue, we analyzed 30-minute recordings of finger and intra-arterial pressure simultaneously obtained at rest in 14 patients. We compared systolic blood pressure, diastolic blood pressure, mean arterial pressure,...
Arterial pressure optimization in septic shock is a critical, yet poorly understood component of resuscitation. New data suggest that, during the routine management of patients with severe sepsis, there is no association between mean arterial pressure achieved and outcome as long as the mean arterial pressure is maintained at or above 70 mmHg. Although these data add important new evidence to o...
the relative importance of systolic (sbp) versus diastolic blood pressure (dbp) and other combinations of sbp and dbp in the prediction of stroke have been re-examined in a long term cohort study of 10,541 men and women aged 45-64 in west scotland. during a mean follow-up of 11.6 years 1, 616 deaths occurred, among which 160 (9.9% 80 male, 80 female) were due to stroke. in a multiple logistic r...
INTRODUCTION Anatomical proximity of the eye and the intracranial space is a fact but the existence of physiological and pathophysiological relationships between them is elusive. The objective of this study was to explore anatomical and pathophysiological interactions between the eye and the intracranial space and to assess clinical utility of intraocular pressure measurement in estimation of i...
To test the hypothesis that the rise in arterial pressure occurring with maturation is due to an increase in the vascular responsiveness to angiotensin II, sequential cumulative doses of angiotensin II were infused intravenously into chronically catheterized newborn lambs maintained on a constant, weight-adjusted sodium intake from birth to 8 weeks of age. Basal mean arterial pressure correlate...
We investigated in conscious Wistar-Kyoto rats the effect of chemical renal medullectomy on the responses of mean arterial pressure, arterial pressure lability, and heart rate to sinoaortic deafferentation (SAD). Chemical medullectomy was obtained by the intravenous administration of 2-bromoethylamine hydrobromide (2-BEA) 2-3 weeks before SAD or sham SAD. Chemically medullectomized rats were co...
