Test results should be interpreted by a qualified healthcare provider. [Content pending medical review.]

Treatment options

Evidence-based approaches to managing this condition.

First-line treatments

1

ACE inhibitors or ARBs

Angiotensin-converting enzyme inhibitors or angiotensin receptor blockers are commonly prescribed to reduce cardiac strain and provide cardioprotective effects in myopathy patients. These medications help manage blood pressure and reduce proteinuria.
