Cardiac sarcoidosis: An algorithmic approach to diagnosis and treatment of the "Great Mimicker"

Area of Science:

• Cardiology
• Rheumatology
• Pathology

Background:

• Cardiac sarcoidosis (CS) is characterized by myocardial infiltration of non-necrotizing granulomas.
• CS presents with diverse clinical manifestations, including life-threatening arrhythmias and cardiomyopathy.
• Accurate diagnosis of CS is essential to distinguish it from mimics and prevent severe patient outcomes.

Purpose of the Study:

• To review diagnostic strategies for cardiac sarcoidosis.
• To outline methods for differentiating CS from clinically similar cardiac pathologies, particularly rheumatologic conditions.
• To discuss current approaches to the management and treatment of CS.

Main Methods:

• Literature review focusing on diagnostic criteria and differential diagnoses for CS.
• Comparative analysis of CS with other cardiac conditions, emphasizing rheumatologic differentials.
• Synthesis of information on CS management and therapeutic strategies.

Main Results:

• CS diagnosis requires careful consideration of clinical presentation, imaging, and biopsy findings.
• Distinguishing CS from conditions like lupus carditis or rheumatoid heart disease is critical.
• Multidisciplinary management involving cardiology and rheumatology is often necessary.

Conclusions:

• Early and accurate diagnosis of CS is paramount for timely intervention.
• Differential diagnosis is key, especially when considering rheumatologic conditions with cardiac involvement.
• Effective management strategies improve patient prognosis and reduce mortality associated with CS.
