When restrictive cardiomyopathy occurs in the setting of sarcoidosis, establishing the underlying diagnosis is essential — it directly determines which targeted therapies are appropriate for this specific patient profile.
This protocol addresses patients with restrictive cardiomyopathy in whom sarcoidosis has been identified as the underlying or co-existing condition. Precise diagnosis in this scenario is a prerequisite for selecting the correct treatment pathway, as the causative process informs the therapeutic approach.

Precise diagnosis is also essential for genetic phenocopies with available target treatments: ERT for Anderson–Fabry disease or glycogenosis such as Pompe disease; therapeutic phlebotomy for haemochromatosis; immunosuppressive therapeutics for sarcoidosis; new biological drugs for systemic diseases (e.g. autoimmune diseases with cardiac involvement that can reverse or stabilize by treating the disease itself); and removal of the toxic causes.
