Summary

Cardiac involvement (CI) is common in primary myopathies (MPs), affecting skeletal and heart muscles. Early cardiac investigation and treatment are crucial for managing MPs and improving patient outcomes.

Area of Science:

  • Cardiology
  • Neurology
  • Genetics

Background:

  • Primary myopathies (MPs) frequently involve both skeletal and cardiac muscle, a condition known as cardiac involvement (CI).
  • CI in MPs can lead to a spectrum of cardiac dysfunctions, including arrhythmias, myocardial thickening, and heart failure.

Purpose of the Study:

  • To highlight the frequent occurrence of cardiac involvement in various primary myopathies.
  • To emphasize the importance of cardiological assessment and management in patients diagnosed with MPs.

Main Methods:

  • Review of literature and clinical findings associated with cardiac involvement in primary myopathies.
  • Analysis of the clinical manifestations and consequences of CI across a range of specific myopathy diagnoses.

Main Results:

  • Cardiac involvement is a frequent complication across numerous primary myopathies, including Duchenne MD, myotonic dystrophies, and glycogenoses.
  • Consequences of CI range from conduction defects and myocardial changes to heart failure with systolic and diastolic dysfunction.

Conclusions:

  • Patients diagnosed with primary myopathies require prompt and thorough cardiological evaluation.
  • Effective cardiac therapy can improve cardiac involvement in MPs, significantly influencing overall patient management and prognosis.
