“Is it normal to have chest pains after angioplasty?”

The goal of revascularization is to relieve all ischemic symptoms (angina). If you are having similar symptoms to pre balloon/stent, it could be due to trapping of a side branch, distal spasm or distal embolization. You need to discuss these symptoms with your cardiologist. There are benign causes as well such as so called “stretch pain” but this is transient. Hope this was helpful!
