[Electrical instability of the myocardium in patients with acquired heart defects.].

Aim of the study was to investigate electrophysiological state of the myocardium and conduct comparative analysis of informative power of methods of dipole electrocardiography and signal averaged ECG with detection of late ventricular potentials for prognostication of ventricular heart rhythm disturbances in patients with acquired heart defects. Examination of 43 patients with acquired heart defects showed that patients with high grade ventricular extrasystoles significantly more often had late ventricular potentials, prolonged interval corresponding to maximal values of activation area, area of fresh activation, and diminished vector of repolarization acceleration and its components.

[Electrical instability of the myocardium in patients with aortic stenosis].

This review of the problems of prognostication of electrical instability of the myocardium in patients with aortic stenosis is based on recommendations of European Society of Cardiology on prevention of sudden death in patients with aortic stenosis with special emphasis on potential of noninvasive assessment of myocardial electric instability (signal averaged ECG, heart rate variability, analysis of variability of QT-interval, dipole electrocardiotopography).

[Microcirculation in hypertension].

Changes of microcirculatory vascular bed play important role in pathogenesis of essential hypertension. All components of the system of microcirculation including vessels and circulating blood are involved into pathological process. Resistance to blood flow is mostly formed in this system. Resistance depends on length, diameter of microvessels and viscosity of blood. In the process of the disease development the following signs of remodeling at the level of microcirculation emerge: decrease of density of vasculature, modification of the media/lumen ratio, increase of blood viscosity, slowing of angiogenesis, impairment of endothelial function. These phenomena can be both cause and consequence of hypertensive disease. Their heterogeneity depends on a variety of factors (duration, stage of the disease, etc.). It seems feasible to differentiate therapy in accordance with character and severity of changes in the system of microcirculation.

[The state of microcirculation in hypertensive disease (essential hypertension)].

Skin microcirculation was studied by laser doppler flowmetry in 149 patients with essential hypertension (92 men, 67 women; mean age 50.1+/-4.9 years) and in 25 normotensive controls. In patients with hypertension prevailed pathological hemodynamic types of microcirculation. Hyperemic, spastic and congestive types were found in 20.1, 23.5 and 40.3% of patients, respectively, while only 16.1% of patients had normal hemodynamic type. Moreover presence and severity of microcirculatory disorders depended on stage of hypertension and level of blood pressure. Thus, patients with essential hypertension had pronounced impairment of microcirculation caused by structural and functional changes of microcirculatory vascular bed.

[Nurse's evaluation of patients' problems as a methodological component in improvement of the quality of nursing care].

Nurse's diagnosis is an integral part of nursing process. Currently used methods within the framework of nursing process do not fully meet the requirements to each discipline. The authors discuss an approach to nurse's diagnosis, which will create prerequisites for developing a principally new standard approach to nurse's participation from a modern viewpoint.
