I had a good friend, Theresa and she had MVP. The mystery was that her physician and therapist made not connection between these co-morbid factors.
The American Heart Association recognizes a connection between mitral valve prolapse and panic attacks although they do not understand the connection.
The prevalence of mitral valve prolapse is substantially greater in patients with autoimmune thyroid disorders such as Graves' Disease and Hashimoto's Thyroiditis.
I have MVP and Graves' Disease but I don't have a panic disorder.
