"Compared to a healthy neighboring section of artery, a narrowed section (as a result of arteriosclerosis) yields"
Answer: decreased height for the manometer reading and a larger blood flow velocity through the constriction.
Explanation: "Using Bernoulli's equation, an increased flow velocity leads to a decreased local pressure against the walls in the narrowed region"
Translation: Less pressure, increased speed
My understanding was that in the unideal fluid dynamics in the body:
Dilating blood vessels:more blood flow, decreased pressure, decreased speed
Constricting blood vessels:less blood flow, increased pressure, increased speed
