when would a doctor not perform coronary angioplasty on a patient ?

Question

Contraindications? I need help here..i have a test for nursing school.

Answer 1

The usual sequence for coronary angioplasty is that the doctor is performing a coronary catheterization, sees which vessels are blocked, then uses angioplasty to open them. (Probably uses stenting as well.)



If the blocked coronary artery is the left main, the doctor would probably not perform angioplasty.



(There are exceptions.)



That might be the answer they're looking for, that left main disease is a contraindication for angioplasty.



If you look at an illustration, you'll see how much of the heart is supplied by vessels that come off the left main artery. If that artery spasmed, or was perforated, or totally occluded, a large part of the heart could infarct.

Answer 2

If the condition does not cause major problem and I guess that proper diet and exercise can take care of the problem. If the coronary arteries are severly blocked or slow the heart rate too much then the surgery is needed.

Answer 3

One likely reason is if there is widespread or diffuse coronary artery disease which will be better treated by grafting (CABG) rather than a more localized angioplasty.

Answer 4

If the disease can be treated through medications by thinning the blood or lowering cholesterol if it is not significant enough, it would be better for the patient to not be put at risk by the procedure.
