In brief: It lowers it

Vasoconstriction increases the resistance to flow.
This is called an afterload. It is like a pump having to pump water up a steep hill; it won't pump as well as on flat land.

In brief: Academic question

Total peripheral resistance (as measured in the cardiac catheterization laboratory) is inversely proportional to cardiac output.
