<bot>: Hello, Brief answer: No chance that old stents in your heart be affected by simple diagnostic cardiac catheterization. Explanation: My opinion is that coronary artery stents are placed in coronary vessels to prevent vessel occlusion by a thrombus. With adherence to anti-ischemic medications and lifestyle modification the preventive rule is completed. Diagnostic coronary angiogram is even more simple procedure, just staining your coronary vessels with a nonionic dye to see if any obstruction or lesions are detected in the study, no wiring or invasive maneuvers done in diagnostic procedure. So hitting your stents is a far-fetched. The information provided by you is not sufficient to provide a good opinion. If someone comes to me with this condition I would ask them about their coronary angiogram report and if any problems in their medications or recurrent typical chest pain is present. Conclusion: I suggest you stick to your medications, if any chest pain developed please revise your physician. Hope I have answered your query. Let me know if I can assist you further.
