Quantitative analysis of spatial organization of the "muscle fibre-capillary" system was performed in 5 normal human hearts. The data on numerical, volumetric, superificial, relative superficial density of capillaries and muscular myocardial fibres were obtained; their total number in the left ventricle wall was calculated. Statistically significant difference of the spatial-quantitative organization in the "muscle fibre-capillary" system in different parts of the left ventricle wall was obtained. Therefore, it can be concluded that selection of myocardial slices for stereometric investigation should be systematized. A mathematical equation for estimating quantitatively capillary blood supply of the myocardial muscle fibres in histological sections was introduced, taking into account volumetric and superficial parameters of the muscle fibres and capillaries.
