Association between local pulse pressure, mean blood pressure, and large-artery remodeling.
BACKGROUND The aim of the present study was to determine the respective influences of local pulse pressure and mean blood pressure on arterial remodeling in humans at 2 arterial sites: a central, predominantly elastic artery (the common carotid artery) and a peripheral muscular artery (the radial artery). METHODS AND RESULTS Forty-three healthy subjects and 124 never-treated hypertensive pati...
متن کاملPeripheral pulse pressure, large arteries, and microvessels.
The aorta is a capacitance vessel that enables transformation of the “on-off” blood-flow characteristics of the left ventricle into a less pulsatile flow in more distal vessels. Thus, a smooth nonpulsatile blood-flow pattern is achieved at capillary level. Arterial wall stiffness determines the degree of energy absorbed by the elastic aorta and its recoil in diastole. Aortic pulse pressure (PP)...
متن کاملEvaluation of various factors relating to intraocular pressure and C/D ratio
Introduction: Intraocular pressure (IOP) is determined by three factors: the rate of aqueous humor production by the ciliary’s body, the resistances to aqueous out flow across the trabecular meshwork and the level of episcleral vessel pressure. IOP varies with a number of factors, including: age, sex, race, systemic disease and diurnal variation. The purpose of this study is measurement of IO...
متن کاملProspective evaluation of a method for estimating ascending aortic pressure from the radial artery pressure waveform.
Pressure wave reflection in the upper limb causes amplification of the arterial pulse so that radial systolic and pulse pressures are greater than in the ascending aorta. Wave transmission properties in the upper limbs (in contrast to the descending aorta and lower limbs) change little with age, disease, and drug therapy in adult humans. Such consistency has led to use of a generalized transfer...
متن کاملThe Ascending Pharyngeal Artery
The ascending pharyngeal artery of the dog was investigated by means of the acryl plastic injection method. This artery usually arose from the external carotid artery, sometimes from the occipital, the posterior auricular, or rarely the ascending palatine of the lingual artery. It ran forwards between the vagus and hypoglossal nerves and continued anteromedially up to the posterolateral wall of...
