  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...

  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...

  Whole blood and plasma viscosity were measured of 90 patients with chronic cerebrovascular disease (CVD) and 56 healthy individuals by Couette rotational viscometer Contraves Low Shear 30 at a steady flow. Plasma viscosity was measured with capillary viscometer of Ubbelohde type. Two subgroups of...

  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...

  Hemorheologic changes from silent to acute and chronic cerebral infarction have seldom been reported. We evaluated hemorheologic profiles of the whole blood viscosity, plasma viscosity and fibrinogen level in stroke at-risk patients with silent cerebral infarction, patients with acute or...

  Hemorheologic parameters were measured in cerebrovascular patients with a history of stroke or recurrent ischemic attacks in a quiescent phase of the disease. All patients were submitted to aortic arch angiography and then classified according to the presence or absence of detectable arterial...

  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...

  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...

  It is known that plasma lipids could increase the cerebrovascular risk through alteration of the hemorheological profile. The aim of the study was to evaluate the relationship between blood viscosity parameters and plasma lipids in patients with cerebrovascular disease (CVD). The study included...

  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...
