Key result
Myasthenia gravis crisis can trigger severe but reversible cardiac complications, including stress-induced cardiomyopathy and arrhythmias, which resolve with treatment of the underlying crisis.
Why the study?
Cardiac involvement in patients experiencing myasthenia gravis crisis is rare and can present as cardiomyopathy, arrhythmia, heart failure, and sudden death.
Case Report (n=2)
No
Stress-induced cardiomyopathy and arrhythmias are rare but potentially life-threatening complications of myasthenia gravis crisis that can resolve with appropriate treatment of the underlying neurological condition.
May warrant cardiac monitoring in MG crisis; leaves open incidence and management questions.
Myasthenia gravis (MG) crisis is a life-threatening condition characterized by respiratory failure requiring intubation and mechanical ventilation.Cardiac problem in patients with MG crisis is a rare condition, presenting as cardiomyopathy, arrhythmia, heart failure and sudden death.We report two cases that developed arrhythmia and stress-induced cardiomyopathy during MG crisis episodes.

Lee et al. (2019) conducted a case report in Myasthenia Gravis Crisis (n=2). Myasthenia gravis crisis was evaluated on Development of cardiomyopathy and arrhythmia. Myasthenia gravis crisis can trigger severe but reversible cardiac complications, including stress-induced cardiomyopathy and arrhythmias, which resolve with treatment of the underlying crisis.
