Age. Increasing age is associated with a decrease in function of blood vessels, including vasodilation. This can contribute to the risk of cardiovascular events such as heart disease and stroke.

How does vasodilation affect stroke volume?

Vasodilation causes increase in blood flow due to decrease in vascular resistance. The resistance produced mainly in the arterioles is known as the systemic vascular resistance (SVR) or the peripheral vascular resistance (PVR). Cardiac output is a function of heart rate and stroke volume.

Are vasodilators safe?

In general, vasodilators are safe when taken as prescribed. However, there are a few groups of people that should avoid these types of meditations. People with severe kidney failure should not take vasodilator ACE inhibitors.
