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 many causes of Hyperesosinophilic Syndrome (HES) with Eosinophilic Cardiomyopathy, these can be classified as:

• Reactive
  • Eosinophillic Granulomatosis Polyangitis
  • Churg Strauss Disease
  • Parasitic Infection
  • Autoimmune disorder
  • Medication related
• Clonal Myeloid Disorder
• Idiopathic Hypereosinophillic Syndrome

Historical Perspective

• Eosinophillic Cardiomypoathy was first discovered by Wilhem Loeffler, a Swiss Physician, in 1936 during/following [event].

• In [year], [gene] mutations were first identified in the pathogenesis of [disease name].
• In [year], the first [discovery] was developed by [scientist] to treat/diagnose [disease name].

Classification

• Eosinophilic Cardiomyopathy may be classified according to cause into three subtypes/groups:

• Reactive
• Clonal myeloid disorder
• Idiopathic hypereosinophillic syndrome

• Other variants of [disease name] include [disease subtype 1], [disease subtype 2], and [disease subtype 3].

Pathophysiology

• The pathogenesis of Eosinophilic Cadiomyopathy is characterized by hypereosinophilia, Restrictive Cardiomyopathy, and Heart failure.
• The FLP1L1-PDGFRA fusion gene has been associated with the development of hypereosiniophilic syndrome.
• On gross pathology, cardiac hypertrophy and fibrosis are characteristic findings of Eosinophilic Cardiomyopathy.
• On microscopic histopathological analysis, hypereosinophilia, myocardial and myofibrillar disarray, and endoperimysial interstitial fibrosis are characteristic findings of Eosinophilic Cardiomyopathy.

Differentiating [disease name] from other Diseases

• Eosinophilic Cardiomyopathy must be differentiated from other diseases that cause Cardiac hypertrophy, cardiac fibrosis, and Heart failure, such as:

• Amyloidosis
• Sarcoidosis
• Hemachromatosis

Epidemiology and Demographics

• The prevalence of Hypereosinophilic Syndrome is approximately 0.036 per 100,000 individuals worldwide.
• In [year], the incidence of [disease name] was estimated to be [number or range] cases per 100,000 individuals in [location].

Age

• Patients of all age groups may develop [disease name].

• [Disease name] is more commonly observed among patients aged [age range] years old.
• [Disease name] is more commonly observed among [elderly patients/young patients/children].

Gender

• [Disease name] affects men and women equally.

• [Gender 1] are more commonly affected with [disease name] than [gender 2].
• The [gender 1] to [Gender 2] ratio is approximately [number > 1] to 1.

Race

• There is no racial predilection for [disease name].

• [Disease name] usually affects individuals of the [race 1] race.
• [Race 2] individuals are less likely to develop [disease name].

Risk Factors

• Common risk factors in the development of [disease name] are [risk factor 1], [risk factor 2], [risk factor 3], and [risk factor 4].

Natural History, Complications and Prognosis

• The majority of patients with [disease name] remain asymptomatic for [duration/years].
• Early clinical features include [manifestation 1], [manifestation 2], and [manifestation 3].
• If left untreated, [#%] of patients with [disease name] may progress to develop [manifestation 1], [manifestation 2], and [manifestation 3].
• Common complications of [disease name] include [complication 1], [complication 2], and [complication 3].
• Prognosis is generally [excellent/good/poor], and the [1/5/10­year mortality/survival rate] of patients with [disease name] is approximately [#%].

Laboratory Findings

• There are no specific laboratory findings associated with [disease name].

• A [positive/negative] [test name] is diagnostic of [disease name].
• An [elevated/reduced] concentration of [serum/blood/urinary/CSF/other] [lab test] is diagnostic of [disease name].
• Other laboratory findings consistent with the diagnosis of [disease name] include [abnormal test 1], [abnormal test 2], and [abnormal test 3].
