What are the risks and recovery expectations?

Risks include bleeding at the catheter insertion site, allergic reaction to contrast dye, stent thrombosis, or artery damage—though these are uncommon with modern techniques. Recovery involves 1–2 weeks of light activity, avoiding heavy lifting or driving. Most patients return to normal daily routines within a few days. Lifelong antiplatelet medication is required to prevent stent clotting, and follow-up angiography may be recommended.
