Which of the following is a contraindication to cardiac catheterization?

Explanation:
Allergic reactions to contrast media or medications used during the procedure can be a contraindication to cardiac catheterization. The test relies on iodinated contrast to visualize the coronary arteries, so a history of allergies to these agents or related meds poses a real risk of a severe hypersensitivity reaction. In such cases, the procedure may be avoided or adjusted with desensitization, premedication, or alternative imaging when appropriate. The other conditions listed—hypertension, obesity, and hyperglycemia—increase peri-procedural risk and may require optimization, but they do not by themselves block the procedure.
