when is someone NOT a candidate for coronary artery bypass surgery?

Question

number of affected vessels, diabetes, smoking, hypertension, left and right ventricular function, kidney failure (dialysis) and numerous other factors impact on bypass surgery, but even with these risk factors, some people can still have bypass surgery. why can't others? just curious.

Answer 1

Depends on the competency is also a major contraindication!!
Absence of an open major artery 1 mm or more in diameter beyond the obstructing lesion.
Non viable myocardium present below the site of CABG; are some of the contraindications although a healthy topic much cannot be written.

Answer 2

All the risk factors need to be weighed to evaluate the possibility of complications and the recovery time. I would add another factor to your list. If a patient has advanced Alzheimer's Disease they are not a good candidate, even if they would otherwise be considered.

My grandfather was refused for this reason. He would not have been able to keep from pulling IVs out and tying him to the bed is not possible. It turned out to be a good thing, he lived another 6 mo. despite not having surgery.

Answer 3

Others cannot because they are judged to have too many risk factors or complicating factors that would negatively impact their ability to survive the surgery or recover appropriately afterward.

Each person is different, their response to surgery will be different. Doctors must carefully weigh all that is happening in a patient's life and in their health when making such a crucial decision.

Answer 4

Low Ejection (EF) Factor is one of the reasons. If the EF is very low, the patient will not come out alive from the OT.

Answer 5

Another is stiff, hard arteries, that could not handle a suture.
