[Factors facilitating development of degenerative aortic valvular stenosis].

The aim of the study was to determine factors of risk and progress of aortal valvular calcinosis (AVC) and aortic ostium stenosis (AOS). The subjects were 85 patients with AVC (42--with aortic valvular stenosis (AVS), and 43--without AOS). The study, which included analysis of the lipid and mineral metabolism, and immunological tests, shows that potential factors of AVC are: age (p < 0.

[Aortic valve stenosis: persistence of infective agents or noninfective inflammatory process?].

The probable risk factors leading to aortic valve calcification are not clearly defined. The cross-sectional study of 85 patients with vascular and valvular calcification was performed. Correlations between the immune tests and aortic stenosis severity were investigated.

["Function-corrected" indexes for precise estimation of aortic stenosis severety].

The aim of the research was to study clinical significance of "function-corrected" indexes (FCI) in non-invasive evaluation of aortic valvular stenosis (AVS) severity. 85 patients with degenerative aortic valve calcification (42 - with AVS and 43 - without aortic ostium (AO) stenosis) were subjects of a cross-sectional study. Significant correlation between AO area and FCI indexes was demonstrated.

[Current technologies for enhancing efficiency of laboratory techniques].

The current approaches to promoting the efficiency of applying the laboratory tools were comprehensively analyzed. It was for the first time that the above issue was considered from the standpoint of a scientifically substantiated management scheme applicable to the laboratory examination volume and within the framework of the modern conclusive medicine. The problem can be solved through starting, in each clinic, an independent research project and through patient management (critical course--technological card) with respect to available technological and personnel resources.
