  While the blood vessels are exposed to high pressures in hypertension, the main complications of hypertension (stroke and myocardial infarction) are paradoxically thrombotic rather than haemorrhagic. To investigate abnormalities of haemorheology (plasma viscosity, fibrinogen), endothelial...

  Blood viscosity studies were carried out in fourteen patients with acute stroke, eight with cerebral infarction, six with cerebral haemorrhage and in thirteen controls. We observed a statistically significant higher values of plasma, red cell and whole viscosity in patients with acute stroke than...

  Thrombotic risk factors may be important in determining cardiovascular outcome in patients with symptomatic peripheral arterial disease. A cohort study with a 6-year follow-up period was established to determine the relationships between haemostatic and rheological factors and incidentischaemic...

  The hypothesis that blood rheology is of prognostic value in stroke patients was tested in a prospective study. A total of 523 patients in the rehabilitation phase of stroke (outside the acute phase reaction after stroke) were tested for blood, serum and plasma viscosity, haematocrit, fibrinogen...

  The effect of isovolemic hemodilution on regional cerebral blood flow (rCBF) and neurological symptoms in 35 patients with acute ischemic stroke was evaluated. Twenty-one patients had internal carotid artery occlusion, and 14 had middle cerebral artery occlusion. Isovolemic hemodilution combined...

  BACKGROUND AND PURPOSE: Spontaneous echo contrast (SEC) is thought to represent a risk factor for cardioembolic stroke. In vitro studies suggest that SEC results from interaction between red cells and fibrinogen. To better understand the relation between SEC and stroke and to investigate the in...

  The origin and significance of blood hyperviscosity in subjects with acute stroke has been controversial. It has been argued that viscous abnormalities simply reflect either elevated hematocrit or an acute-phase response to the stroke itself. To address these issues, we measured the factors that...

  The aim of the present study was the comparative analysis of the role of specific hemorheological derangements in the pathogenesis of ischemicbrain infarcts with and without diabetes mellitus. Blood plasma viscosity, as well as red blood cells (RBC) aggregability were quantitatively investigated...

  The blood viscosity parameters of one hundred and fifty cases of WHO grade I and II hypertension of Indian origin, on treatment with calcium antagonists, were measured and a six-monthly follow up was conducted for a period of three years. The whole blood viscosity (WBV), plasma viscosity (PV),...

  Several lines of evidence indicate that pathologic blood flow properties lead to a deterioration in the prognosis of patients with arteriosclerotic diseases, especially after a stroke. We tested this hypothesis in a prospective study including 625 patients with a first stroke that dated back less...
