Vasoconstriction Overview
Learn About Vasoconstriction
Vasoconstriction is the narrowing (constriction) of blood vessels by small muscles in their walls. When blood vessels constrict, blood flow is slowed or, in extreme cases, completely blocked.
Vasoconstriction may be slight or severe. It may result from disease, medicines, or psychological conditions. Medicines that cause vasoconstriction include:
- Decongestants, including pseudoephedrine
- Cough and cold combinations
Medicines may be used to increase or reduce vasoconstriction in very ill people.

Summary: A study of how supplemental oxygen helps patients with acute pulmonary embolism (PE). Hypothesis: Oxygen affects right ventricular dysfunction (RVD) in patients with acute pulmonary embolism (PE) primarily by relieving hypoxic pulmonary vasoconstriction and reducing pulmonary pressure (PA) pressure, and that this process is metabolically driven.
Summary: Obesity is a major risk factor for hypertensive disorders of pregnancy (HDP). The underlying mechanisms are largely unclear, but maternal vascular endothelial dysfunction is likely involved. Endothelial dysfunction in HDP could be attributed to 1) alterations in the L-arginine/nitric oxide (NO) pathway, and 2) an increase in endothelin-1 (ET-1). Additionally, augmented sympathetic vasoconstriction...
