[Intracardiac volumetric parameters in chronic cardiovascular insufficiency based on autopsy data].
The available methods of direct measurement of volumes of cardiac ventricle cavities cannot be always applied in pathological practice and do not allow the assessment of the residual volumes of ventricles, the amount of the outflowing and inflowing blood. This paper presents a method for the determination of the volume of the blood inflow and outflow as well as the reserve volume of the heart ventricles on the basis of measurements of inflowing and outflowing tracts and perimeters of the valve orifices of the heart ventricles. On the material of 50 autopsy observations (of them 13 controls), changes in the above parameters in hypertension, sudden coronary death and pulmonary-cardiac insufficiency have been demonstrated. In all these kinds of pathology a decrease in the reserve volume (P less than 0.05) and an increase in the outflow volume are observed. Strong correlation associations have been found between the volumetric values in each kind of pathology. The proposed volumetric indices may be used for the assessment of the degree of loading on the ventricular myocardium and of the reserve of hemodynamics compensation.
