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. | ||

*Eosinophillic Cardiomypoathy was first discovered by Wilhem Loeffler, a Swiss Physician, in 1936.<ref>{{Cite journal | |||

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
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
- Eosinophilic cardiomyopathy must be differentiated from other diseases that cause cardiac hypertrophy, cardiac fibrosis, and heart failure[29], such as:
Epidemiology and Demographics
- The prevalence of hypereosinophilic syndrome is approximately 0.036 per 100,000 individuals worldwide. [33]
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
- Common risk factors in the development of eosinophilic cardiomyopathy are HLA Bw44 positivity, splenomegaly, thrombocytopenia, elevated vitamin B12 levels, dysplastic eosinophils, and abnormal early myeloid precursors.[38]
Natural History, Complications and Prognosis
- Some patients with eosinophilic cardiomyopathy may present asymptomatic.[39]
- Early clinical features include dyspnea, fever, and chest pain.[40]
- If left untreated, patients with eosinophilic cardiomyopathy may progress to develop heart failure, arrythmias, and sudden cardiac death.[41]
- Prognosis is generally good, and depends on its etiology.[42]
Diagnosis
Diagnostic Criteria
- The diagnosis of hypereosinophilic syndrome is made when at least one of the following three diagnostic criteria are met:[43] [44]
- 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
- Eosinophilic cardiomyopathy is may present asymptomatic early in the course.[45]
- Symptoms of eosinophilc cardiomypoathy may include the following:[46] [47]
Physical Examination
- Patients with eosinophilic cardiomyopathy usually appear distressed.
- Physical examination may be remarkable for:[48][49]
Laboratory Findings
- A positive cardiac biopsy is diagnostic of eosinophilic cardiomyopathy.[50]
- An elevated concentration of eosinophils in peripheral blood smear is diagnostic of hypereosinophilic syndrome.[51]
- Other laboratory findings consistent with the diagnosis of eosinophilic cardiomyopathy include:[52]
- Abnormal bone marrow biopsy
- Abnormal troponins
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
- Eosinophilic cardiomyopathy may also be diagnosed using ECG.[56]
- Findings on ECG include:[57]
- T wave inversion
- Left atrial enlargement
- Left ventricular hypertrophy
- Right bundle branch block
Treatment
Medical Therapy
- The treatment of eosinophilic cardiomyopathy depends on the underlying cause.
- The mainstay of therapy is supportive care.
- The mainstay of therapy for eosinophilic cardiomyopathy with a FIP1L1-PDGFRA mutation is imatinib and steroids.[58]
- Symptomatic management includes:[59] [60]
- Imatinib acts by inhibition of tyrosine kinase.[61]
- Response to treatment can be monitored with Echocardiography.[62]
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.
- Once diagnosed and successfully treated, patients with eosinophilic cardiomyopathy are followed-up. Follow-up testing includes Echocardiography and Electrocardiogram.[65]
