<unk>  also known as Loeffler's Syndrome is a type of restrictive cardiomyopathy caused by<unk>  infiltration of the endomyocardium. It is a feature of hypereosinophilic syndrome and occurs in 40-50% of all cases.  Eosinophills enter the tissue and undergo degranulation; release cytotoxic proteins; increase production of reactive oxygen species, enzymes, growth factor, and cytokines. This process leads to tissue damage and dysfunction, eventually leading to fibrosis and restrictive cardiomyopathy. There are 3 stages of the<unk> : Stage 1 that is acute necrotic stage, stage 2 that is mural thrombus formation, and stage 3 that is ibrotic stage. There are many causes of hypereosinophilic syndrome (HES) with<unk> , these can be classified as reactive, conal myeloid disorder, and idiopathic hypereosinophillic syndrome.
