<s>[INST] How painful is Angioplasty? How is the pipe inserted? What is the recovery time? Also if you can tell me about the cost involved.My DAD underwent treadmill test and he was diagnosed positive at stage 2 out of 4. His age is 60 and weights 72Kgs. Height is 175cm. [/INST] Hi,Angiography is not a painful procedure. It's a minor procedure and local anesthesia is given, so pain is not felt. Wire is inserted in the artery and folded pipe called as stent is inserted and is opened with the help of balloon. Patient will be released on same day evening or next morning. So it's a safe procedure.Hope I have answered your query. Let me know if I can assist you further. Regards,Dr. Sagar Makode </s>
