[Organometric evaluation of heart changes during systematic physical exercise]. / Organometricheskii analiz izmenenii serdtsa pri sistematicheskikh fizicheskikh nagruzkakh.

Hearts from 23 athletes who had died of traumas were investigated using a morphometric approach that involves external and internal macro-changes measurement, plani-and gravimetry, histostereometry, and morpho-statistical treatment. Hypertrophic heart was found in all the cases, while the ratios between quantitative parameters of individual heart muscle departments, as well as nuclear-cytoplasmatic and stromal-parenchymatous relationships and myocardial blood supply were within normal range. It was demonstrated that only a certain portion of myocardial muscular cells, responsible for intensified operation, became hypertrophic in response to systematic exercise.

[Morphometric study of the hypertrophied heart]. / Morfometricheskoe izuchenie gipertrofirovannogo serdtsa.

Diagnostic potentials of morphometric methods in studies of right-ventricle and left-ventricle hypertrophy of the heart were analysed. Different cardiometric methods were found to give dissimilar information on the quantitative changes in parts of the hypertrophic heart. Composite morphometry using the methods of individual weighing, external-internal, planimetric-weight, and histometric determinations followed by their mathematical treatment was found to reveal the dynamics of the quantitative parameters of hyperfunctioning heart parts most objectively.
