Question

If a stent is not used in a few cases that have coronary angioplasty done, the artery tends to narrow down or get blocked again in 6 months. This is more likely to happen if:
A. One smokes
B. One has unstable angina before the procedure
C. One has diabetes
D. All of these

Answer 1

Hint:
Before we proceed into the problem, it is important to know the definition of Coronary angioplasty.
Coronary angioplasty (CABG) is a procedure that is used to unblock an obstruction in the coronary artery. This can be caused by atherosclerosis, a build-up of plaque on the inner walls of your arteries. CABG involves using a balloon to expand the narrowed section of the artery and open it up again.

Complete answer:
During the same procedure, most people who have angioplasty also have a stent inserted in their clogged artery. A stent, which resembles a tiny coil of wire mesh, supports the walls of your artery and prevents it from narrowing again following angioplasty.
The artery tends to narrow down or get blocked again. This is more likely to happen if: The patient has diabetes mellitus or if the patient smokes cigarettes or if there are any other underlying medical conditions that might affect the vessel's ability to dilate.
Therefore, the artery tends to get blocked if, one smokes, has unstable angina before the procedure, and if he has diabetes.

Option ‘D’ is correct

Note:
One should avoid intense exertion and carry heavy objects, for at least a day after. Inquire with your doctor or nurse about any other activity limits. If the location where your catheter was implanted begins to bleed or swell, contact your doctor's office or hospital staff promptly.
