- The most common cardiac manifestations of myotonic dystrophy are due to conduction system disease
- Cardiac disease is responsible for 30% of deaths in patients with myotonic dystrophy
- The 12 lead electrocardiogram is the most useful risk stratification tool for predicting sudden death
- Proactive treatment of patients with evidence of conduction system disease with pacing improves outcomes
Myotonic dystrophy (MD) is a multisystem, autosomal dominant disorder best known for its skeletal muscle manifestations. Cardiac manifestations arise as a result of myocardial fatty infiltration, degeneration and fibrosis and present most commonly as arrhythmias or conduction disturbances. Guidelines regarding the optimal cardiac management of patients with MD are lacking. The present article provides a summary of the pathophysiology of cardiac problems in patients with MD and provides a practical approach to contemporary cardiac monitoring and management of these patients with a focus on the prevention of complications related to conduction disturbances and arrhythmias.Methods: A literature search was performed using PubMed and Medline. The keywords used in the search included “myotonic dystrophy”, “cardiac manifestations”, “heart”, “arrhythmia”, “pacemaker” and “defibrillator”, all terms were used in combination. In addition, “myotonic dystrophy” was searched in conjunction with “electrophysiology”, “electrocardiogram”, “echocardiograph”, “signal averaged electrocardiograph”, “magnetic resonance imaging” and “exercise stress testing”. The titles of all the articles revealed by the search were screened for relevance. The abstracts of relevant titles were read and those articles which concerned the cardiac manifestations of myotonic dystrophy or the investigation and management of cardiac manifestations underwent a full manuscript review.
