[Tableau d'insuffisance cardiaque congestive révélant une myocardite lupique : cas clinique]

Area of Science:

• Immunology
• Cardiology
• Rheumatology

Background:

• Systemic lupus erythematosus (SLE) is an autoimmune disease where the immune system mistakenly attacks healthy tissues.
• Lupus myocarditis, a serious cardiac manifestation of SLE, affects 3-9% of patients.
• Early diagnosis of lupus myocarditis is crucial for managing SLE patients.

Observation:

• A patient with established multisystem SLE presented with new-onset heart failure.
• Severe left ventricular dysfunction was detected during the cardiac evaluation.
• These findings suggested an underlying cardiac inflammatory process.

Findings:

• The patient's presentation of de novo heart failure was attributed to lupus myocarditis.
• Severe left ventricular dysfunction was a key indicator of the cardiac involvement.
• This case underscores the potential for cardiac complications in SLE.

Implications:

• Recognizing heart failure as a potential symptom of lupus myocarditis is vital for timely intervention.
• This case emphasizes the need for cardiac monitoring in SLE patients.
• Understanding lupus myocarditis can improve patient outcomes and management strategies.
