orthostatic intolerance/ischemia

We investigated the alteration in flow-dependent-dilatation in the orthostatic intolerance occurring after bed-rest deconditioning. Eight men [aged mean (SEM) 32 (2) years] underwent two consecutive periods of 7 days of head-down-tilt (HDT, -6 degrees) during bed rest. A control age and sex matched

OBJECTIVE Generalized cerebral ischaemia from cardiovascular dysfunction usually leads to presyncopal dizziness, but several studies reported a higher frequency of rotatory vertigo in cardiovascular patients. Whether generalized cerebral ischaemia due to cardiovascular disorders may produce

Cardiovascular autonomic neuropathy associated with diabetes mellitus is caused by an impairment of the autonomic system. The prevalence of this condition ranges from 20% to 65%, depending on the duration of the diabetes mellitus. Clinically, the autonomic function disorder is associated with

In healthy male volunteers the effect of a short-term cerebral ischemia due to an acute orthostatic hypotension, on the release of growth hormone (HGH) was studied. Peroral administration of guanethidine 12.5 mg t.i.d. for 3 days plus 25 mg before the experiment was used to block peripheral vascular

The effect of transient cerebral ischaemia connected with acute orthostatic hypotension on plasma adrenaline and noradrenaline levels was studied in seven healthy male volunteers during tilt. Sublingual administration of 1 mg nitroglycerin was used to block peripheral vascular reflexes and thus to

BACKGROUND Sedentary lifestyles and physical deconditioning are commonly reported among persons with spinal cord injury (SCI), although many forms of exercise have been shown to be beneficial. For individuals unable to perform voluntary exercise, involuntary exercise by electrically stimulated

Diabetic autonomic neuropathy (DAN) is a serious and common complication of diabetes. Despite its relationship to an increased risk of cardiovascular mortality and its association with multiple symptoms and impairments, the significance of DAN has not been fully appreciated. The reported prevalence

Cardiac autonomic neuropathy (CAN) is a serious complication of diabetes mellitus (DM) that is strongly associated with approximately five-fold increased risk of cardiovascular mortality. CAN manifests in a spectrum of things, ranging from resting tachycardia and fixed heart rate (HR) to development

Cardiac autonomic neuropathy (CAN) is a common complication in type 1 and 2 diabetes and is defined as the impairment of autonomic control of the cardiovascular system. CAN is strongly associated with increased mortality, and in some studies with morbidity of vascular complications, such as stroke,
