An Index of Peripheral Vascular Resistance
Journal of Hypertension, 1985An index of peripheral vascular resistance, derived from directly measured arterial pressure, has been developed and tested in an animal model. Assuming a mono-exponential character for diastole, the time constant for direct arterial pressure decay in the central aorta was obtained with high-fidelity recording techniques from six anaesthetized dogs ...

Calculation of coronary vascular resistance
Cardiovascular Research, 1980A conscious, chronically instrumented canine model was used to investigate resistance changes in the distribution of the circumflex coronary artery as the artery was constricted. Several discrete constrictions were studied at two different levels of flow: resting and peak flow reactive hyperaemia.

Insulin resistance and vascular function
Journal of Diabetes and its Complications, 2002It has become clear that amongst its many actions insulin is also a vasoactive hormone. Its effect to cause endothelial-nitric oxide-dependent vasodilation is physiologic and dose-dependent. Recent data suggest that insulin's metabolic and vascular actions are closely linked.

Estrogen and vascular resistance
Current Opinion in Endocrinology & Diabetes, 1999Male sex and menopause are independent risk factors for cardiovascular disease. Estrogens bind to vascular receptors, including the novel estrogen receptor-β and membrane-bound receptors, and they contribute to vascular resistance through several mechanisms.

Hematocrit-corrected Pulmonary Vascular Resistance
American Journal of Respiratory and Critical Care Medicine, 2018The diagnosis and evaluation of severity of pulmonary vascular disease rests on the invasive determination of a pulmonary vascular resistance (PVR). It is often overlooked that PVR is linearly related to the viscosity of the blood, which in turn is curvilinearly related to hematocrit.

The focus of this chapter is on understanding the complexity associated with the resistance to flow through the pulmonary circulation. Pulmonary vascular resistance (PVR) is a variable that reflects the physical size (diameter and length) of the vascular tree at any moment in time.

The height of the systemic vascular resistance is largely dependent on the total cross-sectional area of the arterioles in the peripheral vasculature. The smooth muscle tone of these vessels is influenced by neural, humoral, and local environmental factors.
