Vasoconstrictions mediated by an endothelium-derived vasoconstricting factor (EDCF)

Basic Research in Cardiology, 1989
To enlighten the role of endothelium in the generation of vasospasms we examined vascular tone after reduction of oxygen supply in dependence on endothelial function in isolated vessels (rabbit aorta abdominalis, pig coronary, and pulmonary artery).

Hypoxic Pulmonary Vasoconstriction

Physiological Reviews, 2012
It has been known for more than 60 years, and suspected for over 100, that alveolar hypoxia causes pulmonary vasoconstriction by means of mechanisms local to the lung. For the last 20 years, it has been clear that the essential sensor, transduction, and effector mechanisms responsible for hypoxic pulmonary vasoconstriction (HPV) reside in the pulmonary

Hypoxic pulmonary vasoconstriction

Journal of Applied Physiology, 2005
Humans encounter hypoxia throughout their lives. This occurs by destiny in utero, through disease, and by desire, in our quest for altitude. Hypoxic pulmonary vasoconstriction (HPV) is a widely conserved, homeostatic, vasomotor response of resistance pulmonary arteries to alveolar hypoxia.

Hypoxic pulmonary vasoconstriction

General Pharmacology: The Vascular System, 1999
Hypoxic vasoconstriction is unique to pulmonary circulation. The pulmonary response is part of a self-regulatory mechanism by which pulmonary capillary blood flow is automatically adjusted to alveolar ventilation for maintaining the optimal balance of ventilation and perfusion. In pathological conditions, hypoxic pulmonary vasoconstriction may occur as

Vasoconstriction and long-term headache in reversible cerebral vasoconstriction syndrome

Journal of Neurology, 2022
Angiographic vasoconstriction in reversible cerebral vasoconstriction syndrome (RCVS) is often undetectable at symptom onset and the diagnosis relies on clinical presentation. Although thunderclap headache is a hallmark feature of RCVS, the incidence and predictors of long-term headaches (LTH) are incompletely understood.

Mechanisms of vasoconstriction

American Heart Journal, 1991
The contractility of vascular smooth muscle cells is controlled in a complex manner by both extracellular and intracellular messages. The vascular endothelium does not simply act as a physical barrier between the blood and smooth muscle cells, it integrates intravascular signals and controls the contractility of underlying smooth muscle cells by way of

Diseases of Vasoconstriction

Postgraduate Medicine, 1960
Vasoconstriction of some degree is almost always present in the skin of the extremities; it is more active in peripheral sites. Vasoconstriction may be caused by stimuli of central origin or by reflexive responses to peripheral stimuli. Cold and posture are the most significant causes of reflexive stimuli. Abnormal vasoconstriction is seen in Raynaud's
