About Vascular Function / Reactivity

Vascular reactivity is a vital component of vascular function that enables adjustments of blood flow and alterations of vessel tone and diameter, when needed. Healthier arteries have higher vasodilative capacity and are more reactive. Multiple factors, including known cardiovascular risk factors (hypertension, diabetes, smoking) as well as genetic, environmental, and other detrimental factors, reduce the vasodilative capacity.
