[|AI|]  Hello dear, Thank you for your contact to Chat Doctor. I read and understand your concern. I am Chat Doctor answering your concern. After angioplasty such a problem is common, but you should keep eye on it. If you develop some further patches than immediately contact the nearby doctor. After angioplasty doctors can prescribe the anticoagulant medication. This medication can sometimes on some places causes red patch. Development of further red patch is indicative of higher anticoagulation and should be corrected immediately with the vitamin K therapy. Right now you should keep the medication continued and contact for further complication. I will be happy to answer your further concern on bit.ly/ Chat Doctor.
