Purpose Of The Review: Cardiac involvement in systemic sarcoidosis or isolated cardiac sarcoidosis plays a pivotal role in the clinical manifestation and prognostication. Active-inflammatory cardiac sarcoidosis is associated with a regional impairment of coronary microvascular function that may confer further detrimental effects on myocardial function needing further characterization.

Recent Findings: Clinical investigations with cardiac positron emission tomography/computed tomography in conjunction with F-fluorodeoxyglucose to determine myocardial inflammation and N-ammonia to quantify myocardial blood flow (MBF) in patients with known or suspected cardiac sarcoidosis outlined that sarcoidosis-induced myocardial inflammation was associated with adverse effects on corresponding regional coronary microvascular function. Notably, immune-suppressive treatment caused reductions in myocardial inflammation were paralleled by improvements of coronary microvascular dysfunction outlining direct adverse effect of inflammation on coronary arteriolar function. This review summarizes contributions of cardiac PET imaging in the identification and characterization of active-inflammatory cardiac sarcoidosis, its effect on coronary microvascular function, treatment responses, and prognostic implications.

Background: Ventricular tachycardia (VT) in patients with cardiac sarcoidosis (CS) can lead to sudden cardiac death. The role of ventricular tachycardia ablation (VTA) in CS has been investigated in a few small, single-center, and larger observational studies, but the evidence still needs to be provided. This study aimed to investigate the clinical outcomes of VTA in patients with CS admitted with a diagnosis of VT.

Background: Cardiac sarcoidosis (CS) is associated with poor prognosis, making early diagnosis and treatment important. This study evaluated the results of a diagnostic approach in patients with known sarcoidosis and suspected cardiac involvement in a tertiary centre and their long-term outcomes.

Methods: We included 180 patients with sarcoidosis and a clinical suspicion of CS.

Background: Recent studies have focused on treating cardiac sarcoidosis (CS) with corticosteroids primarily mitigating symptoms and reducing the risk of mortality and other cardiovascular complications. A promising new treatment approach involves tumor necrosis factor (TNF) alpha inhibitors.

Methodology: A systematic search was conducted on PubMed, the Cochrane Library, and Elsevier's Science Direct databases to identify studies comparing TNF alpha inhibitors with other drugs in CS patients who had heart failure.

Sarcoidosis is an inflammatory multisystem disease characterised by non-necrotising granulomas that typically affect the lungs, lymph nodes, eyes, skin, liver, spleen, heart, bones and joints. Although rare, necrotising granulomas can also occur. In this report, we present a case of a healthy woman in her 60s who presented with a 1-year history of fatigue and generalised body aches.

: ACE (angiotensin-converting enzyme) is considered a serological marker of sarcoidosis as elevated levels have been reported in 30-80% of patients. However, elevated ACE levels are also encountered in other medical conditions, and the clinical correlation between ACE levels and disease activity in sarcoidosis is disputable as well. To determine the significance of elevated ACE levels in the diagnosis and follow-up of sarcoidosis patients.
