[Structure of the venous and lymphatic beds of the heart and their alteration in experimental pathology].

The investigation performed has demonstrated that under a great deal of coronary, pulmonary and other organs' disorders, in the venous and lymphatic beds of the heart compensatory-adaptive and pathological changes occur. The earliest and deepest changes are noted in the microcirculatory bed. Most of morphological signs on vascular reconstruction are not specific and are observed at different kinds of clinical and experimental pathology. Changes in venous and lymphatic vessels of pathological conditions& do not only result from damage in the organ's wall or hemodynamical changes in the cavities of the cardiac vessels but they themselves can cause some disturbances in the miocardial microcirculation intensifying its hypoxia, congestive symptoms and enhancing the development of decompensation in the organ.
