End-stage renal disease (ESRD) is complicated by high blood pressure (BP) and severe atherosclerosis, which may lead to different values of BP measured by invasive and noninvasive methods. However, the differences in BP values between these two methods and their possible mechanisms in ESRD have not been investigated. Forty-one ESRD ...

Abnormalities in nocturnal blood pressure dipping are well known for its relationship to cardiovascular diseases. Cerebral microbleeds are frequently observed in patients with hypertension and are known to be potent risk factors for stroke. However, there are scanty reports about the relationship between nocturnal dipping and cerebral microbleeds. We recruited ...

Activation of the carotid body chemoreceptors with hypoxia alters baroreceptor mediated responses. We aimed to examine whether this relationship can be translated to other chemoreceptor stimuli (i.e. hypoglycaemia) and hypothesized: 1) activation of the carotid body chemoreceptors with hypoglycaemia would reduce spontaneous cardiac baroreflex sensitivity (sCBRS) in healthy humans and, ...

Horn players have observed that timpani strokes can interfere disruptively with their playing, especially when they are seated close to the timpani. Measuring the horn's transfer function in the bell-to-mouthpiece direction reveals that the horn behaves as an acoustic impedance matching device, capable of transmitting waves with pressure gains of ...

The pathogenesis underlying communicating hydrocephalus has been centered on impaired cerebrospinal fluid (CSF) outflow secondary to abnormal CSF pulsation and venous hypertension. Hydrodynamic theory of hydrocephalus fares better than traditional theory in explaining the possible mechanisms underlying communicating hydrocephalus. Nonetheless, hydrodynamic theory alone could not fully explain some conditions that ...

Arterial pulse pressure has been widely used as surrogate of stroke volume, for example, in the guidance of fluid therapy. However, recent experimental investigations suggest that arterial pulse pressure is not linearly proportional to stroke volume. However, mechanisms underlying the relation between the two have not been clearly understood. The ...

Idiopathic intracranial hypertension is a disorder of increased intracranial pressure of unknown cause. Idiopathic intracranial hypertension can present with a wide spectrum of neurological signs, especially cranial nerve palsies, which are mostly thought to be caused by a pressure-dependent stretching mechanism. Treatment is guided by aetiology whenever possible; otherwise drainage ...

No longitudinal study addressed whether systolic blood pressure level (SBPL) or within-visit variability (SBPV) predict arterial properties or vice versa. In families randomly recruited from a Flemish population, we determined SBPL and SBPV from five consecutive blood pressure readings. The indexes of SBPV were variability independent of the mean, the ...

Hypertension is one of the most important risk and modifiable factors for stroke. Crucial in managing the cerebrovascular damage caused by long-lasting and inadequately treated hypertension is not only lowering arterial blood pressure but also early predicting subtypes of hypertension-related stroke and applying more effective interventions. Accumulating evidence suggested that ...

Object The differential pressure between the intracranial and intraperitoneal cavities is essential for ventriculoperitoneal shunting. A determination of the pressure in both cavities is decisive for selecting the appropriate valve type and opening pressure. The intraperitoneal pressure (IPP)-in contrast to the intracranial pressure-still remains controversial with regard to its normal ...

Hypertension is the leading risk factor for ischemic and intracerebral hemorrhagic subtypes of stroke. Additionally, high blood pressure (BP) in the acute cerebrovascular event is associated with poor outcome, and a high percentage of stroke survivors have inadequate control of hypertension. The present is a systematic review of prospective, randomized, ...

Apart from the well-known role of hypertension in cerebrovascular disease, visit-to-visit blood pressure (BP) variability is emerging as an independent risk factor for stroke. Although the underlying mechanism is not fully understood, artery remodeling is thought to be closely involved in the relationship between visit-to-visit BP variability and stroke. This ...

Intracranial pressure elevation, peaking three to seven post-stroke is well recognized following large strokes. Data following small-moderate stroke are limited. Therapeutic hypothermia improves outcome after cardiac arrest, is strongly neuroprotective in experimental stroke, and is under clinical trial in stroke. Hypothermia lowers elevated intracranial pressure; however, rebound intracranial pressure elevation ...
