What is Myopathies?
Myopathies are diseases that affect the skeletal muscles (those attached to bones).

Congenital myopathies are muscle diseases present at birth (congenital) that result from genetic defects in your muscle development. Congenital myopathies may cause you to have muscle weakness and breathing and eating problems.
The inflammatory myopathies are a group of diseases, with no known cause, that involve chronic muscle inflammation accompanied by muscle weakness.
Cardiomyopathies often lead to congestive heart failure (CHF), which is not a disease in itself or failure of the heart to beat.
Definition Myopathies are diseases of skeletal muscle which are not caused by nerve disorders. These diseases cause the skeletal or voluntary muscles to become weak or wasted.
Mitochondrial myopathies are a group of neuromuscular diseases caused by damage to the mitochondria-small, energy-producing structures that serve as the cells' "power plants.
Mitochondrial myopathies can cause a range of symptoms. Some people experience very few symptoms. Others may experience the full range. If you have any of these symptoms, do not assume it is due to mitochondrial myopathy.

They tend to develop in people with coronary artery disease and heart muscle diseases (cardiomyopathies). They are life- threatening.
Conditions called 'myopathies' - in which there is muscle weakness. Some myopathies are temporary problems and are not genetic.
Other conditions called 'neuromuscular disorders'.

Myopathies including muscular dystrophies - many different types of muscular dystrophy (muscle wastage) are caused by various genetic mutations that prevent the maintenance and repair of muscle tissue.
ACE inhibitors and angiotensin receptor blockers have additive effects in treating patients with cardiomyopathies and proteinuria.
Dermatomyositis is one of a group of acquired muscle diseases called inflammatory myopathies. The disease has a subacute (somewhat short and relatively severe) onset. It affects both children and adults. Females are more often affected than males.
Idiopathic inflammatory myopathies - For polymyositis and dermatomyositis, doctors begin treatment with a corticosteroid drug, usually prednisone (sold as a generic). If this fails, methotrexate (Rheumatrex) or azathioprine (Imuran) may be added.

Dermatomyositis belongs to a group of conditions called inflammatory myopathies. Myopathies are diseases or abnormal conditions of the striated muscles that cover your skeleton. The cause of most inflammatory myopathies is unknown.
Kearns-Sayre Syndrome belongs (in part) to a group of rare neuromuscular disorders known as mitochondrial encephalomyopathies.

Doctors suspect that myopathies are autoimmune disorders, in which your body's immune system mistakes normal components of your body for foreign substances and attacks them.
Myopathies for example are some of the most serious skeletal diseases which in turn affect the muscles as well as the nerves. Millions of people have different types of myopathies, most of which are degenerative although that is not always the case.
Two of the most common cardiomyopathies are ischemic (due to poor blood supply to the heart muscle as described above) and hypertensive.
Among the mitochondrial myopathies, CPEO is the most common manifestation, estimated at two-thirds of all incidences of mitochondrial associated myopathies.
Dermatomyositis and Polymyositis are two forms of inflammatory myopathies - diseases of muscle caused by an immune response. They cause muscle weakness as their major symptom, and dermatomyositis also causes a skin rash.
Diseases of the heart muscle (cardiomyopathies).
Heart valve disease Opens New Window.
Disease of the sac around the heart (pericardial disease), such as pericarditis Opens New Window.
Polymyositis and dermatomyositis are diffuse, inflammatory myopathies that produce symmetrical weakness of striated muscles, especially proximal muscles of the shoulder, pelvic girdle, neck, and pharynx.
It belongs to a group of muscle conditions called the congenital myopathies that tend to affect people in a similar pattern. Major symptoms may include loss of muscle tone (hypotonia) and generalized muscle weakness.
Diseases of the heart muscle (cardiomyopathies).
Heart valve disease.
Disease of the sac around the heart (pericardial disease), such as pericarditis.
A slow, fast, or uneven heart rhythm (arrhythmia).
One of the mitochondrial encephalomyopathies characterised by myoclonic epilepsy and ragged red fibres of muscle tissue. Red muscle tends to be rich in mitochondria. Biochemical tests disclose changes in the enzymes of the respiratory chain.
X-linked myotubular myopathy is a member of a group of disorders called centronuclear myopathies. In centronuclear myopathies, the nucleus is found at the center of many rod-shaped muscle cells instead of at either end, where it is normally located.
