Insights
Cardiac sarcoidosis (CS) is an inflammatory heart condition. Diagnosis relies on imaging, while treatment involves steroids, immunosuppressants, or biologics like TNF-α inhibitors for severe cases.
Area of Science:
- Cardiology
- Immunology
- Inflammatory Diseases
Background:
- Cardiac sarcoidosis (CS) is a complex inflammatory condition impacting the heart.
- It can lead to serious complications including arrhythmias, heart failure, and sudden cardiac death.
Purpose of the Study:
- To provide a comprehensive review of current diagnostic and treatment strategies for cardiac sarcoidosis.
- To synthesize existing knowledge on managing this multifaceted disease.
Main Methods:
- This narrative review synthesizes current literature on CS diagnosis and treatment.
- Key diagnostic tools include imaging modalities like cardiac MRI and PET scans.
- Treatment strategies discussed encompass corticosteroids, immunosuppressants, and biologics (e.g., TNF-α inhibitors).
Main Results:
- Endomyocardial biopsy, though the gold standard, has limitations in sensitivity and carries risks.
- Cardiac magnetic resonance and positron emission tomography are vital for diagnosis and management.
- Current treatments focus on reducing inflammation and disease progression, with biologics reserved for refractory cases.
Conclusions:
- Effective diagnosis and management of CS require a multimodal approach.
- Imaging plays a crucial role in overcoming biopsy limitations.
- Personalized treatment strategies, including advanced therapies, are essential for improving patient outcomes.
Abstract:
Cardiac sarcoidosis (CS) is a multifaceted inflammatory disease that affects the heart, leading to complications such as arrhythmias, heart failure, and sudden cardiac death. Endomyocardial biopsy is the diagnostic gold standard, but its low sensitivity and risks limit its utility. Imaging modalities, such as cardiac magnetic resonance and positron emission tomography, are critical for diagnosing and managing CS. Additionally, CS treatment primarily involves corticosteroids and immunosuppressive agents to reduce inflammation and control disease progression, although biologics such as tumor necrosis factor-alpha (TNF-α) inhibitors are considered in refractory or steroid-dependent cases. This narrative review revises the existing knowledge on the diagnosis and treatment of CS, providing a comprehensive overview of current strategies.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
