[Peculiarities of the relationship between atherosclerotic lesions of carotid arteries and the severity of cardiac pathology in elderly patients].

The study was aimed at elucidating the relationship between the severity of atherosclerotic lesions in carotid arteries and cardiac pathology in 182 elderly patients subjected to vascular and extravascular surgical treatment. They were divided into 2 groups differing in the degree of atherosclerosis. Group 1 was comprised of 93 patients (mean age 64+/-05 yr) without stenosis of internal carotid artery or with stenosis of less than - 50%, group 2 included 89 patients (mean age 67+/-0.5 yr) with hemodynamically significant stenosis of internal carotid artery. It was shown that carotid stenosis over 50% is frequently associated with the history of myocardial infarction and stable angina of effort. An increase of the degree of stenosis was accompanied by a decrease of stroke and minute volumes.

[Microbiological monitoring in prophylaxis and treatment of pyoinflammatory complications during early postoperative period in patients with cicatricial tracheostenosis].

The species composition and antibiotic susceptibility of microflora isolated from patients with cicatricial tracheostenosis (CTS) and infectious processes were investigated. Schemes for the treatment of CTS with an account of the pathogen species and multidrug resistant staphylococcal infection are described. Comparative efficacy of the combined schemes (antibiotic + bacteriophage) for the therapy of pyoinflammatory processes in the patients with CTS and the efficacy of the treatment of the patients with CTS according to the traditional antibacterial schemes were studied.

[The respiratory system im chronic pyelonephritis]. / Sostoianie respiratornoi sistemy pri khronicheskom pielonefrite.

The respiratory system was studied in 221 patients with chronic pyelonephritis (CP), satisfactory renal function and varying arterial pressure (AP) using tests of systemic hemodynamics, echocardiography, zonal rheography of the lungs and rheospirography. Ventilation-perfusion correlations were also taken into account. It is shown that the respiratory system, along with circulatory organs, is involved in the pathological process at early stages of pyelonephritic inflammation. Patients with the so-called "normal high AP" develop vascular dysfunction in the lungs manifesting in enlarged pulmonary artery base without an increase in pressure gradient in it, gradual growth of resistance of not only systemic vascular bed of the greater but lesser circulation as well, ventilation dysfunction of the lungs by the restrictive type, imbalance between the ventilatory reserve and reserve of pulmonary and systemic blood flow with progression of arterial hypertension.

[The status of respiratory organs in hypertensive patients]. / Sostoianie organov dykhaniia u bol'nykh gipertonicheskoi bolezn'iu.

The condition of the respiratory system in essential hypertension was studied with the tests of general hemodynamics, echocardiography, zonal rheography of the lungs and rheospirography with estimation of ventilation-perfusion relations. Hypertension was found to affect not only cardiovascular but also respiratory system. Hypertension-related respiratory disorders present as vascular dysfunction in the lungs, restrictive defects of pulmonary ventilation, imbalance between the ventilatory reserve and reserve of the pulmonary and systemic blood flow with progression of arterial hypertension.
