Be patient with your friend. Sometimes it takes a while to find the right combo of meds and therapy that works best.

It is possible to be genetically disposed to MI. It is also possible to have MI for no apparent reason. No one who is not a doctor can say what causes it or what the best course of treatment is. It seems that some people who have dealt with MI have become experts on it. I am no expert. I only know what has worked for me. I would not be here if not for certain medications.
