Chapter 31: Problem 10

Features of the vulnerable plaque include: a. more prone to rupture b. heavy inflammatory cell infiltrate c. thin fibrous cap d. a, b and c e. \(\mathrm{a}\) and \(\mathrm{c}\)

Short Answer

Expert verified

Answer: The correct features of a vulnerable plaque include being more prone to rupture, having a heavy inflammatory cell infiltrate, and a thin fibrous cap.

Step by step solution

Examine option (a) - more prone to rupture

A vulnerable plaque is indeed more prone to rupture, which can lead to complications such as heart attacks and strokes. Therefore, option (a) is a correct feature of a vulnerable plaque.

Examine option (b) - heavy inflammatory cell infiltrate

Vulnerable plaques often have a higher number of inflammatory cells, which can create a more unstable environment and contribute to their increased risk of rupture. Thus, option (b) is also a correct feature of a vulnerable plaque.

Examine option (c) - thin fibrous cap

Vulnerable plaques typically have a thinner fibrous cap. The thin cap is weaker and less able to resist rupture when subjected to stress caused by blood flow or other factors. Therefore, option (c) is a correct feature of a vulnerable plaque.

Determine the correct answer

Since options (a), (b), and (c) are all accurate features of a vulnerable plaque, the correct answer is option (d), which combines these three features.
