Dilated cardiomyopathy - what does this mean
What happens during the disease - dilated cardiomyopathy
Под действием причинных факторов уменьшается количество функционально полноценно кардиомиоцитов, что сопровождается расширением камер сердца и снижением насосной функции миокарда. Дилатация сердца приводит к диастолической и систолической дисфункции желудочков и обусловливает развитие застойной сердечной недостаточности в малом, а затем и в большом круге кровообращения.
На начальных стадиях дилатационной кардиомиопатии компенсация достигается благодаря действию закона Франка–Старлинга, увеличению ЧСС и уменьшению периферического сопротивления. По мере истощения резервов сердца прогрессирует ригидность миокарда, нарастает систолическая дисфункция, уменьшается минутный и ударный объем, нарастает конечное диастолическое давление в левом желудочке, что приводит к еще большему его расширению.
В результате растяжения полостей желудочков и клапанных колец развивается относительная митральная и трикуспидальная недостаточность. Гипертрофия миоцитов и формирование заместительного фиброза приводят к компенсаторной гипертрофии миокарда. При уменьшении коронарной перфузии развивается субэндокардиальная ишемия.
Вследствие снижения сердечного выброса и уменьшения почечной перфузии активизируются симпатическая нервная и ренин-ангиотензиновая системы. Выброс катехоламинов сопровождается тахикардией, возникновением аритмий. Развивающиеся периферическая вазоконстрикция и вторичный гиперальдостеронизм приводят к задержке ионов натрия, увеличению ОЦК и развитию отеков.
У 60 % пациентов с дилатационной кардиомиопатией в полостях сердца формируются пристеночные тромбы, вызывающие в дальнейшем развитие тромбоэмболического синдрома.
