First-line treatments
Disease management and monitoring
Active treatment with regular monitoring by a healthcare provider is recommended.
Implantable Cardioverter-Defibrillator (ICD)
Surgical placement of an ICD device to continuously monitor heart rhythm and deliver electrical shocks if life-threatening arrhythmias occur. This is essential given the documented association between myopathy and sudden cardiac death.
Beta-Blocker Therapy
Chronic beta-blocker administration to reduce cardiac workload, control heart rate, and decrease risk of arrhythmias. Standard heart failure medical therapy combined with ICD provides layered protection.
Additional treatment options
Periodic Cardiac Rhythm Monitoring
Regular ambulatory monitoring with Holter or event recorders to detect silent arrhythmias and assess ICD function. Frequency based on symptom burden and device interrogation schedules.
monitoringGenetic Counseling and Family Screening
Comprehensive genetic evaluation and counseling for the patient and first-degree relatives to identify at-risk family members who may benefit from prophylactic monitoring or early intervention.
psychologicalActivity Restriction and Exercise Guidance
