hello, I have gone through your query.Thanks for using HCM.First of all let me tell you that after undergoing angioplasty one need to to continue certain medicines like aspirin,Clopidogrel and statin for life long.This is needed to prevent restenosis on stent and to prevent newer blocks at other sites. Kirslow is antioxidant which you may continue ,but Aspirin and Statin are most important.Antioxidants are helpful but not must following angioplasty.So better discuss with your treating doctor before stopping, My best wishes Dr.Rajesh Teli,MD.
