What are the risks associated with angioplasty?

Angioplasty carries several risks, including bleeding or bruising at the catheter insertion site, blood clots, and arterial damage. There's also a potential for infection and the possibility of restenosis, where the treated artery narrows again over time. In rare cases, complications like heart attack, stroke, or kidney damage may occur, especially in patients with pre-existing health conditions. Overall, while angioplasty is generally safe, it's important for patients to discuss their individual risks with their healthcare provider.
