Abstract

Aim: It is to summarize and in a new way to interpret the data, which have been earlier received, in order to prove the development of the hibernation of myocardium (HM) in cases of the neuroleptic cardiomyopathy (NCMP).

Methods and results: Morphometric methods of research were used which meet modern requirements of the evidence-based medicine. The studied micro morphometric parameters describe the condition of three structural components of myocardium (vasculature, intercellular matrix, and parenchyma). Such parameters as zone of pericapillary diffusion (ZPD), Kernogan index (KI), SPR, RIE were calculated. Karyometry and cytometry of cardiomyocytes (CMCs) were performed, the specific volumes of hypertrophied CMCs (SVHC), of atrophied ones (SVAC), and – by the method of polarization microscopy – the specific volume of dystrophic ones (SVDC) were determined. When NCMP is absent, the changes, which have an acute character, develop in the case of SCD and NMS and reflect the statistically significant shifts of the respective quantitative parameters. When NCMP is present, the only parameter, which is significantly changed in connection with SCD and NMS, is SVDC.

Conclusion: NCMP causes irreversible damages in myocardium, it leads to its are activity, practically almost fully prevents it from reacting to any influences, particularly to the coming of SCD and/or development of NMS. The found morpho functional state of cardiac muscle in the case of NCMP is an independent proof of state of HM which appears during the process of morphogenesis of NCMP
