Aim: To estimate the time course of clinical changes in patients with asthma during combination therapy using ceruloplasmin (CP).

Materials And Methods: A total of 92 asthmatic patients were examined. Their medical history data were collected; external lung function testing and clinical, laboratory, and instrumental examinations, involving the determination of the indicators of lipid peroxidation (LPO) (malonic dialdehyde (MDA), methemoglobin, carboxyhemoglobin) and the antioxidant system (superoxide dismutase (COD), sulfhydryl groups), were performed in all the patients over time.

This paper summarizes results of the investigations into the influence of antioxidants on the clinical picture of bronchial asthma. This disease is known to be accompanied by hyperactivation of lipid peroxidation. The use of antioxidants permits to correct free-radical oxidation (peroxidation) and enhances effectiveness of control over clinical symptoms.

Chronic obstructive pulmonary disease and coronary heart disease frequently occur in combination. Systemic inflammation concomitant with protracted COPD is the pathogenetic mechanism of CHD. High concentration of the markers of systemic inflammation is associated with deterioration of atherosclerosis, its complications, and CHD progression.

Positive changes are declared to occur during recent years in management of hospitalized patients with acute coronary syndromes (ACS) in Russia. Most of these changes are related to availability of invasive treatment. But considerable portion of patients (pts) are still treated in hospitals without facilities for invasive myocardial revascularization (noninvasive hospitals - NIHs).

Background: Complete following existing guidelines for management of acute coronary syndrome (ACS) is known to be associated with better outcomes. Partly this is explained by lesser adherence to recommendations in high risk patients. Aim of our study was to assess relationship between degree of following current guidelines and in hospital outcomes independently from initial assessment of risk.

Aim: To estimate the time course of changes in basic electrocardiographic (ECG) parameters in patients with acute coronary syndrome (ACS) as possible predictors of in-hospital outcomes.

Materials And Methods: The data of 277 patients with acute coronary syndrome (ACS) were used; QT-interval duration was studied by means of an EC12C-01 cardioanalyzer; ST-segment deviation (sigmaST), elevation (sigmaST-E), and depression (sigmaST-D) sums, and corrected QT-interval dispersion (DQTc) were calculated.

Results: There were highly significant differences of sigmaST in all the patients groups at admission and differences of DQTc in ACS patients with and without ST-segment elevation.

This review concerns the role of acquired androgen deficiency in pathogenesis of chronic cardiac failure (CCF) in men. It shows that patients with CCF and CHD suffer reduced testosterone production that correlates with impaired contractile activity of myocardium. It means that androgen deficiency due to combined bronchopulmonary and cardiovascular pathology promotes the early development of CCF.

The number of patients with chronic cardiac failure (CCF) grows continuously in the last decades especially among aged subjects compared with younger ones. Mortality and hospitalization rates among elderly subjects are also higher Hence, the importance of early diagnosis and treatment of concomitant diseases aggravating CCF, e.g.

The aim of the study was to evaluate the prevalence and characteristics of ventricular extrasystole in patients developing metabolic syndrome. 24 hour echoCG monitoring was performed in 112 subjects above 15 yr meeting AHA/NHILBI 2005 criteria for metabolic syndrome corrected for the European population and in 107 metabolically neutral subjects. Significant differences were documented in the frequency of polytopic extrasystole (63.

In the last decades, the possibility to use blood cells for delivery of pharmaceutical agents directly into a lesioned tissue has been given increasingly more attention. In the context of extracorporeal pharmacotherapy, the most promising approach is the use of autoerythrocytes possessed of unique morphological and physiological characteristics. Application of erythrocytes as containers for various drugs decreases the risk of side effects and pathologic immune reactions against encapsulated agents, permits to modify their pharmacokinetic and pharmacodynamic properties for reducing single and corse doses and intervals between them.

The aim of the work was to evaluate the prevalence of cardiac rhythm and conductance disturbances in patients with early manifestations of metabolic syndrome (MS). 24-hour ECG monitoring was undertaken in 105 patients meeting AHA/NHLBI (2005) MS criteria and in 79 healthy subjects. Exclusion criteria were the presence of diabetes mellitus, CHD, and obesity (body mass index > 40 kg/m2).

This paper reviews prevalence of chronic cardiac insufficiency and effects of depression and anxiety conditions on its clinical course and prognosis. Clinical and experimental findings are discussed with reference to the role of the rennin-angiotensin-aldosterone system in pathogenesis of chronic cardiac insufficiency, depression, and certain psychic and nervous diseases. Special attention is given to the influence of CAE inhibitors on mental health of elderly subjects.

Aim: To examine electrophysiological characteristics of the phenomenon of the atrioventricular curve gap (ACG) in patients with metabolic syndrome (MS).

Material And Methods: The study included patients aged over 15 years with ACG. Electrophysiological characteristics of this phenomenon were compared in 55 patients with MS (by NCEP ATP III 2001 criteria) and 47 free of MS.

Aim: To study prevalence of androgen deficiency and its relations with clinicopsychological disorders in males with ischemic heart disease (IHD).

Material And Methods: A total of 87 males aged 31-60 years (58 with stable angina of effort FCII-III, 29 with progressive angina of effort) participated in the study. Clinical symptoms of androgen deficiency, severity of anxiety and depression, quality of life were characterized with scales AMS, HADS, D.

This review is dedicated to the role of age-related acquired androgenic deficit in coronary heart disease (CHD) pathogenesis. The analysis of literature show that decrease of testosterone production in males leads to development of dyslipidemia, coronary atherosclerosis, obesity and to increase of blood trombus potential. Thus, androgen deficit potentiates early CHD development in males.

Two groups of patients with pneumonia were observed: the main group consisted of patients with pneumonia accompanied by chronic viral hepatitis B (CVHB), and the control group contained patients without CVHB. Main group patients displayed higher activity of lysosomal and redox enzymes, as well as imbalance in the proteinase-inhibitory system and bronchial lavage phospholipid spectrum. Concomitant CVHB impaired the protective function of the lungs and thus delayed the resolution of pneumonia.

A new prognostic criterion was developed to evaluate the severity of different forms of viral hepatitis, by studying zinc metabolism. In patients with viral hepatitis, zinc metabolic disturbances were ascertained to occur concurrently with pigment, protein, and carbohydrate metabolic disturbances, an increase in the activity of some serum enzymes (glutamine alkaline transferase, glutamine pyruvate transferase, alanine aminotransferase), and a reduction in hepatic antitoxic function. The indicator of normalization of zinc metabolism may be an additional prognostic criterion for evaluating the full recovery of a patient.

To study the pattern and incidence of arrhythmias in relation to the mean pulmonary trunk pressure (MPTP), 24-hour SCG monitoring and Doppler pulse EchoCG were performed in 32 patients with chronic obstructive lung disease and in 13 patients with bronchial asthma. The summarized results of 24-hour ECG suggest that the number and grades of arrhythmias increase when MPTP becomes more than 13 mm Hg. There is a highly significant mean force correlation between MPTP and complicated cardiac arrhythmias (paroxysmal supraventricular tachycardia, coupled ventricular extrasystoles, and unsteady ventricular tachycardia).
