<s>[INST] Hi, Could you tell me how long you would have to wait to fly after heart surgery.  My aunt had a heart attack and they operated using keyhole surgery to unblock the artery.  She would like to know does she have to wait several months before she can fly as we have had lots of different advice from people? [/INST] N I if the surgery was fine, no residual blockages remain, and she is comfortable she can fly as early as 2 weeks with no risk.  However, she should be strict with the time of medication and shouldn't miss any.  The whole purpose of keyhole surgery is so that the patient can get back to normal as soon as possible.  However, on final note the surgeon who did the surgery would be the best to take a call.  Regards Chat Doctor.  </s>
