In the pathological education, the shells of the heart valves are most often involved, in which ulcers or ulcers appear along with polyps. The damaged valve can not function properly, due to which its insufficiency is formed. The ulcers often appear on the mitral valve, and rarely on the aortic valve. Protoss spread rapidly and may eventually reach the tendon chords along with the wall-mounted endocardium.
Yuqumli aktiv endokardit
Patologik ta`limda yurak klapanlarining qobig'i ko'pincha ishtirok etadi, bu erda yaralar yoki yaralar polip bilan birga paydo bo`ladi. Zarar ko'rgan vana to'g'ri ishlamayapti, buning natijasida uning etishmovchiligi shakllanmoqda. Xo'ppozlar ko'pincha mitral qopqoqda, kamdan-aorta qopqog'ida paydo bo'ladi. Protoss tez tarqaldi va oxir-oqibat devorga o'rnatilgan endokard bilan birga tendon tokchalariga erishishi mumkin.
Affected valves become a place of accumulation of fibrin with platelets. Due to the layers of these blood components, the valves swell, they are pierced by fibrin. As a result, the risk of detachment of the tendon chords or individual parts of the valve increases. Also, the vessels can be clogged with broken thrombus, which entails the development of septic infarction. If the process "dies", then it happens wrinkling and deformation of the valves, which causes the disorders of hemodynamics, conductivity of the heart, etc.
Ta'sir klapanlar trombotsitlar bilan fibrin to'plash joyiga aylanadi. Ushbu qon tarkibiy qismlarining qatlamlari tufayli klapanlar shishadi, ular fibrin bilan teshiladi. Natijada tendon oqimlari yoki valfning alohida qismlari ajralib chiqish xavfi ortadi. Bundan tashqari, tomirlar singan tromboz bilan tiqilib qolishi mumkin, bu esa septik infarktni rivojlanishiga olib keladi. Agar jarayon "o'ladi" bo'lsa, u holda gemodinamikaning buzilishiga, yurakning o'tkazuvchanligiga va boshqalarga ta'sir qiluvchi vanalarning ajralishi va deformatsiyasi bo'ladi.
Known as a protracted endocarditis. May be associated with the development of pneumococcal infection, but more often occurs with the background of infection with streptococcus, hemolytic or normal. The pathological process is mainly involved in the aortic valve, which was subjected to sclerosis or other changes.
The course of the disease is often associated with the recurrence of the pathological process, which increases the risk of formation of infarcts of various organs, as well as focal inflammation in the kidneys. In addition, the spleen may increase, progressing anemia that was previously present.
Uzoq muddatli endokardit deb ataladi. Pnevmokokk infektsiyasining rivojlanishi bilan bog'liq bo'lishi mumkin, lekin tez-tez streptokokklar, gemolitik yoki normal infektsiyali fon bilan yuzaga keladi. Patologik jarayon asosan sklerozga yoki boshqa o'zgarishlarga duchor bo'lgan aorta qopqog'iga aloqador.
Kasallikning rivojlanishi ko'pincha patologik jarayonning takrorlanishiga bog'liq bo'lib, u turli organlarning infarktlarini shakllantirish xavfini oshiradi, shuningdek buyraklardagi fokal yallig'lanishni oshiradi. Bundan tashqari, ilgari mavjud bo'lgan anemiya rivojlangan, taloq ortishi mumkin.
