Eosinophillic Cardiomyopathy also known as Loeffler's Syndrome is a type of restrictive cardiomyopathy caused by eosinophillic infiltration of the endomyocardium.<ref>{{Cite journal
Eosinophillic Cardiomyopathy also known as Loeffler's Syndrome is a type of [[restrictive cardiomyopathy]] caused by eosinophillic 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 eosinophilic cardiomyopathy: 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 eosinophilic cardiomyopathy, these can be classified as reactive, conal myeloid disorder, and idiopathic hypereosinophillic syndrome.

Overview

Eosinophillic Cardiomyopathy also known as Loeffler's Syndrome is a type of restrictive cardiomyopathy caused by eosinophillic 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 eosinophilic cardiomyopathy: 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 eosinophilic cardiomyopathy, these can be classified as reactive, conal myeloid disorder, and idiopathic hypereosinophillic syndrome.

Historical Perspective

  • Eosinophillic Cardiomypoathy was first discovered by Wilhem Loeffler, a Swiss Physician, in 1936.[1] [2]

Classification

  • Eosinophilic Cardiomyopathy may be classified according to cause into three subtypes/groups:[3][4]

Pathophysiology

  • The pathogenesis of eosinophilic cadiomyopathy is characterized by hypereosinophilia [11], thrombi formation [12], restrictive cardiomyopathy[13] [14], and heart failure [15].[16]
  • The FLP1L1-PDGFRA fusion gene has been associated with the development chronic eosinophilic leukemia [17]and hypereosiniophilic syndrome.[18] [19]
  • The PDGFRa, PDGFRb, and PDGFR1 genes have been associated with the development of clonal myeloid disorders leading to hypereosiniophilic syndrome.[20] [21]
  • On gross pathology, cardiac hypertrophy and fibrosis are characteristic findings of Eosinophilic Cardiomyopathy.[22]
  • On microscopic histopathological analysis, hypereosinophilia, myocardial and myofibrillar disarray, and endoperimysial interstitial fibrosis are characteristic findings of Eosinophilic Cardiomyopathy.[23]

Clinical Features

Differentiating [disease name] from other Diseases

Epidemiology and Demographics

Age

  • Patients of all age groups may develop ecosinophilic cardiomyopathy.[34]
  • Eosinopilic cardiomyopathy is more commonly observed among patients aged 20-50 years old.[35]

Gender

  • Men are more commonly affected with eosinophilic cadiomyopathy than Females.[36]
  • The male to female ratio is approximately 1.47. [37]

Race

  • There is no racial predilection for eosinophilic cardiomyopathy.

Risk Factors

Natural History, Complications and Prognosis

  • Prognosis is generally good, and depends on its etiology.[42]

Diagnosis

Diagnostic Criteria

  • An elevated eosinophil count (>1500/mm3) on 2 separate tests (≥1 mo).
  • Tissue hypereosinophilia based on >20% eosinophils in a bone marrow section.
  • Marked disposition of eosinophilic granule proteins in tissue plus organ damage directly due to hypereosinophilia.

Symptoms

Physical Examination

Laboratory Findings

Imaging Findings

  • Cardiac MRI is the imaging diagnostic study of choice for eosinophilic cardiomyopathy.[53]
  • On cardiac MRI, eosinophilic cardiomyopathy is characterized by hyper-enhancement and thrombus formation.[54]
  • Echocardiography may demonstrate:[55]
    • Endomyocardial thickening
    • Ventricular thrombus formation
    • Mitral valve involvement

Other Diagnostic Studies

Treatment

Medical Therapy

Surgery

  • Valve replacement may be performed for patients with valvular damage in eosinophilic cardiomyopathy.[63]
  • Cardiac transplant may be performed for patients with irreversible damage in eosinophilic cardiomyopathy.[64]

Prevention

  • There are no primary preventive measures available for eosinophilic cardiomyopathy.
