[The morphological characteristics of the cardiac lymphatic bed in chronic coronary failure]
Insights
Lymph stasis contributes to myocardial fibrotization in chronic ischemic heart disease (IHD). This study reveals lymph stasis has cardiotoxic and sclerogenous properties, impacting heart tissue in IHD patients.
Area of Science:
- Cardiovascular Pathology
- Lymphatic System Research
- Ischemic Heart Disease
Background:
- Chronic ischemic heart disease (IHD) involves complex pathological changes.
- The role of lymphatic circulation in IHD pathogenesis requires further elucidation.
Purpose of the Study:
- To investigate morphological changes in the lymphatic circulation of the heart in chronic IHD.
- To evaluate the impact of lymph circulation disorders on myocardial fibrotization.
Main Methods:
- Examination of intraoperative cardiac biopsies and post-mortem heart tissues from IHD patients (36-59 years).
- Utilized transmission electron microscopy for detailed morphological analysis.
- Compared lymphatic changes in intramyocardial and subepicardial regions.
Main Results:
- Identified significant morphological alterations in the heart's lymphatic system in chronic IHD.
- Observed evidence of lymph stasis within the myocardial and subepicardial regions.
- Correlated lymph stasis with myocardial fibrotization.
Conclusions:
- Lymph stasis is a key pathogenetic factor in myocardial fibrotization in chronic IHD.
- The observed lymph stasis exhibits cardiotoxic and sclerogenous properties.
- Understanding lymphatic dysfunction is crucial for managing chronic coronary insufficiency.
Abstract:
A study is presented of the morphological changes of the lymphatic circulation in chronic ischemic heart disease (IHD). Examinations were carried out on clinical material: intraoperative cardiac biopsies and on hearts of patients who died of this disease at the age of 36-59 years. Transmission electron microscopy was used. A clinical comparison was realized of changes of intramyocardial and subepicardial regions of the heart lymph circulation and morphological equivalents of disorders of outflow of lymph from the heart in chronic IHD were evaluated. The obtained data indicate the lymph stasis possessing cardiotoxic and sclerogenous properties is an essential pathogenetic factor of myocardial fibrotization in chronic coronary insufficiency.
