<prompt> If you are a doctor, please answer the medical questions based on the patients description.My father, 81, after a 4 bypass surgery back in the 80s has undergone a stentbaloon procedure two days ago at NYU hospital. Two arteries were disconnectedblocked. He is home now. Has been prescribed: Aspirin, Plavix, Pletal for 6 months. He is now complaining of chest pain. Is that normal after the procedure?  <response>: Hello There After going through your medical query I understand your concern and I would like to tell you that chest pain is persisting because of blocked arteries and that specific area of the arteries is not getting enough oxygen. It is recommended for you to consult your treating cardiologist and ask him to add some anti-anginal Chat Doctor. Hopefully this information will guide you properly. Kind Regards
