The prognosis of multicore myopathy is not usually good when cardiac involvement is present. [ncbi.nlm.nih.gov]

Prognosis In the majority of patients, weakness is static or only slowly progressive, with the degree of respiratory impairment being the most important prognostic factor. [orpha.net]

PROGNOSIS If the underlying cause of the myopathy can be treated successfully, as in the case of endocrine myopathies, the prognosis is usually good. [consultantsinneurology.com]

They are organised into groups, and further divided into clinical, etiological or histopathological sub-types. [orpha.net]

In all cases a hereditary etiology to the disorders is obvious presumably by an autosomal recessive trait. Fibres with central nuclei and multiple minicores was a prominent finding in all cases. [ncbi.nlm.nih.gov]

Although the etiology of restrictive disease is often idiopathic, known causes include endomyocardial fibrosis, infiltrative disorders (amyloidosis, hemochromatosis and sarcoidosis), carcinoid syndrome, systemic sclerosis and radiotherapy to the chest [clinicaladvisor.com]

The clinical diagnosis was dilated cardiomyopathy of un- known etiology. [myslide.es]

It is suggested that in myotubular myopathy membrane dysfunction causing decreased ionic gradients is an important feature of the pathophysiology while in multicore myopathy other mechanisms, as a suggestion related to mitochondrial and myofibrillar function [ncbi.nlm.nih.gov]

Pathophysiology Dilated cardiomyopathy is a disease process of many causes that affect heart muscle function eventually resulting in diminished cardiac output and symptoms of heart failure. Presentation may be acute or chronic. [clinicaladvisor.com]

Determining the genetic defect in these patients will help to clarify the pathophysiological alterations that lead to fibre type disproportion. Myalgia was not a feature in previously described patients with multicore disease. [jnnp.bmj.com]
