[Dilatation (congestive) cardiomyopathy: clinical aspects, diagnosis and treatment]. / Dilatatsionnaia (zastoinaia) kardiomiopatiia: klinika, diagnostika i lechenie.

Clinical and electrocardiographic manifestations of congestive cardiomyopathy are considered on the basis of observations of 25 patients with this pathology of the myocardium. No clinico-electrocardiographic signs specific for this disease were found. Most characteristic were cardiomegaly, congestive cardiac failure and various disturbances of rhythm and conductivity. Thromboembolic complications in the lung and kidney vessels are frequently found. Cardiac glycosides, saluretics and vasodilators were employed in the treatment of patients with congestive cardiomyopathy but the prognosis was usually poor.

[Current approaches to the early diagnosis of primary subacute infectious endocarditis]. / Sovremennye podkhody k rannei diagnostike pervichnogo podostrogo infektsionnogo éndokardita.

A study of 22 patients with a diagnosis of primary infectious endocarditis based on clinical, laboratory and instrumental (electro-, phono- and echocardiography) investigation showed the fever syndrome and rigors to be the main clinical manifestations of the disease. Echocardiography can contribute to its early diagnosis, while increased erythrocyte sedimentation rate remains the most valuable diagnostic test.

[Left ventricular function of patients with chronic nonspecific lung diseases]. / Funktsiia levogo zheludochka u bol'nykh s khronicheskimi nespetsificheskimi zabolevaniiami legkikh.

Echocardiographic studies of left ventricular function were carried out in 20 patients with chronic unspecific pulmonary diseases (CUPD). These patients showed no true left ventricular myocardial hypertrophy, while electrocardiographic signs of the latter might be related to the recording of potentials from the hypertrophic ventricular septum produced by positional cardiac changes due to pulmonary emphysema. In addition to septal hypertrophy, end diastolic left ventricular size was shown to be diminished. A hypothesis is proposed for the pathogenesis of left ventricular pumping disorders associated with CUPD.

[Electrical impedance tomography in pulmonology]. / Elektroimpedansnaia tomografiia v pul'monologii.

Application of a modern method of introscopy--electroimpedance tomography (EIT) for diagnosis of different types of lung diseases is described. The EIT system including measurement and collecting data devices, 16-electrodes array and IBM PC 486 computer was used. The results of analysis of electrotomograms have demonstrated that the EIT-system can be introduced for detecting abnormal lung fluid levels, pulmonary edema, diagnosis of lung cancer, emphysema, pleuritis, hydrothorax, sarcoidosis. The method provides high sensitivity to the changes in the body physiological state. Other advantages are: safety, fast measurements, ease of equipment transportation and maintenance, low cost.

[Respiratory and hemodynamic disorders in the participants in the cleanup of the aftermath of the accident at the Chernobyl Atomic Electric Power Station]. / Respiratornye i gemodinamicheskie narusheniia u lits, uchastvovavshikhsia v likvidatsii posledstvii avarii na Chernobyl'skoi AES.

After examination of cardiorespiratory function in 10 males exposed to Chernobyl accident unfavorable factors at the age of 31-45 years suffering from chronic obstructive bronchitis (7 cases) and mixed bronchial asthma (3 cases) it was established that the patients had ventilation disorders of mixed genesis (moderate obstructive and respiratory affections), frequently occurring decreased specific diffusion (DLCO/Va) in normal total diffusion capacity of the lungs, inefficient gas exchange, midly declined left ventricular pump capacity and contractility. In the above patients a relationship was found between parameters of central hemodynamics assessed at echo-CG and severity of ventilation impairment and respiratory insufficiency.
