How do I prepare for cardiac catheterization if I have diabetes?

If you have diabetes, prepare for your cardiac catheterization (an x-ray that uses dye to see how the blood flows through the heart veins) by following these steps:
  • Take your usual dose of insulin the night before, including Lantus insulin.
  • If you take morning insulin, take only half of your usual dose.
  • Have the nursing staff check your blood sugar when you come to the hospital.
  • If you take diabetes medication by mouth, do not take your diabetes medication the night before or the morning of your procedure.
