Summary

The theses is related on 297 pages, and consists of introduction, 8 chapters, conclusions, practical recommendations, abstracts in Romanian, English, Russian and bibliography of 229 sources. Illustrative mater contains 40 tables and 298 figures. The results are published in 94 scientific works.

Domain of research: functional cardiology.

Aim of research: Evaluation of artery elasticity indices with central hemodynamics indices in patients with left ventricle diastolic and systolic dysfunction, as well as in vitro estimation of the peripheral vascular and coronary reactivity.

Objectives of research: Estimation of the pathophysiological interrelations concerning artery elasticity indices and left ventricle indices dependently of heart failure evolution pattern and therapy, the in vitro assessment of aorta and coronary system vasomotricity in experimental heart failure.

Solved scientific problem in this study: Have been underlined the opportunities of interdependence between big and small artery elasticity indices and heart geometric and functional changes characteristic to left ventricle diastolic or systolic dysfunction. Methodology of scientific study: echocardiography, artery elasticity indices assay thereby pulsatile wave analysis, „handgrip” test, rat isolated aorta rings and isolated heart perfusion.

Novelty and originality of research: Primary was evaluated the trait of big and small artery elasticity indices correlation with heart geometric and functional parameters in patients with diastolic or systolic dysfunction, as well as the influence of diverse therapeutic approaches.

Applied value:Is emphasized the role of the artery elasticity disorders in hemodynamics impairments development which may be improved by hypotensive and hypolipemiant treatment.

Practical implementation: The study results were proven as scientific point and have been implemented in the clinic of the Institute of Cardiology.
