Cardiomyopathy is a disease in which the heart muscle (myocardium) first suffers, which leads to its serious disorders, changes in the structure.

Medicine is known for three types of cardiomyopathy. They have completely different clinical manifestations, different prognosis, but they have the general signs that allow them to be united under this name:

  • There may be no signs of an inflammatory reaction in the body;
  • Slightly enlarged heart size;
  • The tendency of the organism to form blood clots;
  • There is a heart failure, with great difficulty being treated.

Dilated cardiomyopathy

This type of cardiomyopathy is 9% of all cases of heart failure. The incidence of diseases in this type ranges from 3 to 10 cases per 100,000 men.

The very causes of dilated cardiomyopathy are not fully understood. There is an assumption that this type of cardiomyopathy may be hereditary, since registered cases of the disease at once in several relatives. Many researchers came to the conclusion that the debut has a viral nature, but to isolate the virus that causes dilated cardiomyopathy, until no one was able.

The first symptoms of the disease are not specific, they can not immediately determine what it is cardiomyopathy. This may be fatigue (even with low physical activity), weakness, shortness of breath or cardiac asthma. Often there are pain in the heart - aching, prickly, gripping.

Diagnosis is established only on the basis of echocardiography. X-ray of the heart and electrocardiography are only additional diagnostic methods.

Hypertrophic cardiomyopathy

This type of cardiomyopathy is 0.2% of all cardiomyopathies. Most often young people are ill, and this disease progresses with each passing day. It is with this kind of cardiomyopathy a high probability of sudden death of the patient, and today it is 2-4%.

Hypertrophic cardiomyopathy proceeds quite varied. Some patients do not complain about any symptoms from the cardiovascular system, others have a difficult condition from the very beginning. Very often patients with hypertrophic cardiomyopathy are accompanied by angina attacks, even cardiac fainting is possible.

Restrictive cardiomyopathy

This is the rare form of cardiomyopathy. It can be both independent, the main human disease, and related - with amyloidosis, hemochromatosis, Fabry disease, scleroderma, and others.

The main symptoms of this type of cardiomyopathy - shortness of breath, weakness, fast fatigue under physical activity, heart failure may develop.
