Etiology of acquired heart diseases

The main reason for the formation of acquired heart defects is, as you know, a history of endocarditis.
Endocarditis (endocarditis-inflammation of the inner lining of the heart. The first description of inflammation of the endocardium belongs J. Buyo (1835). He offered to call this pathological process endocarditis, for the first time revealed the etiologic link the past with rheumatism; it was proved that acquired heart diseases develop due to endocarditis. In 1838, M. Sokolsky in the monograph "the Doctrine of breast diseases" emphasized the close link between rheumatoid arthritis and acquired heart diseases that often arise from "nadogradi" and incorrect treatment of rheumatism.
When endocarditis inflammatory process is most often localized in the field of valves. Such endocarditis is called valve. Most often affects valves left parts of the heart (mitral, somewhat less aortic), less tricuspid and very rarely valve pulmonary artery.
The inflammatory process may be localized in the area of chords (hardly endocarditis), papillary muscles, endocardium, lining the inner surface of the Atria and the ventricles (the parietal endocarditis); the last localization is quite rare.
The defeat of the endocardium mainly arises as a result of exposure to microbes or their toxins (streptococci, staphylococci, and others)were an Important role in the development of endocarditis is owned and sensitization of the body. In 70-80% of children endocarditis is a manifestation of rheumatism (A. N. Volovik, 1948), the 2nd place on the frequency can be put septic endocarditis.
On etiological principle all endocarditis can be divided into 3 large groups:
I. Rheumatic endocarditis.
II. Septic endocarditis (bacterial).
III. Endocarditis different etiology:
1. Traumatic (postoperative).
2. Tuberculous.
3. Non-bacterial endocarditis (endocarditis caused by uremia, diabetic coma).
4. Endocarditis caused by collagenoses.
5. Endocarditis caused by myocardial infarction.
6. Endocarditis other etiology.
On the severity of the disease and the severity of the forecast endocarditis divided into benign and malignant.
Postmortem endocarditis are divided into warty, diffuse (rheumatic valvular), ulcers, fibrinous.
Downstream there are endocarditis acute, subacute, chronic, continuous-recurrent, and primary and recurrent.
