Hello @jamesyoung and welcome to Mayo Clinic Connect. While those of us on Connect are not medical staff, this community is made up of patients and caregivers who share their experiences to help others. I can understand if you are confused by falling into a borderline category with such a serious condition.

Can I start by asking if you are looking to confirm the myocardiopathy given the borderline diagnosis by your current physician? If so, are you interested in a second opinion?
