Myocarditis and primary Sjögren's syndrome

Area of Science:

• Cardiology
• Rheumatology
• Immunology

Background:

• Primary Sjögren's syndrome is a systemic autoimmune disease primarily affecting exocrine glands.
• Cardiac involvement in Sjögren's syndrome is rare, with autoimmune myocarditis being an uncommon manifestation.

Observation:

• A case of congestive heart failure was observed in a patient diagnosed with primary Sjögren's syndrome.
• The heart failure was attributed to autoimmune myocarditis, an inflammatory condition of the heart muscle.

Findings:

• The patient presented with symptoms and laboratory findings consistent with congestive heart failure.
• Corticosteroid therapy was initiated for the autoimmune condition.
• Treatment with corticosteroids led to the resolution of both cardiac symptoms and laboratory abnormalities.

Implications:

• This case highlights the importance of considering autoimmune myocarditis as a cause of heart failure in patients with primary Sjögren's syndrome.
• Early diagnosis and prompt immunosuppressive treatment, such as corticosteroids, may be crucial for managing cardiac complications in this patient population.
• Further research is warranted to understand the mechanisms and prevalence of cardiac involvement in Sjögren's syndrome.
