The best heart failure medications that my EP and heart failure doctors recommended to me were, Entresto, Coreg (Carvididol), Eplerenone, Mexiletine, Atorvastin. And supplements, Fish oil and magnesium.

The only medication I had that caused allergic reactions was a type of medication Elerenone (it started with an S) is and it caused back pain, nipple and breast pain. Immediately took off and put on the Elerenone and I was able to tolerate it but one of side affects is breat enlargement. Already a overweight guy and did not need this but recent blood tests show a reduction of irritation in my heart.

I know you probably have read this or are going to but who are you seeing? You need to be seeing a heart failure specialist. They go through additional training above a cardiologist and then specifically treating heart failure. My heart failure specialist is the Director of heart failure at Mayo Clinic Jacksonville. Have been seeing him since 2006.

Do you live anywhere close to a Mayo Clinic or a Cleveland Clinic. I would try to go there for second opinions and or care. What I did when I first got heart failure I did not live close to Mayo Clinic Jacksonville (3 hours away). But my major treatment was still at Mayo Clinic. What Mayo asked me to do was have a local cardiologists who would agree to work with Mayo and see me on a local basis and ongoing as well as my visits to Mayo Clinic.

This worked out great and both specialist coordinated my treatments and testings. I moved to Jacksonville area in 2015 and then had just my heart failure specialist at Mayo. I also see a EP at Mayo (Director of electrophysiology at Mayo Jacksonville) since 2006 also. Both my EP and HF worked together as a team to make sure getting best medications and ensure each concurs with the medications, tests and treatments.

I know that is a lot but if you can get a very large experienced heart failure institute to be your major provider and set up your mediations and treatment program and worked with a local cardiologist as a team.
