[Functional study of the heart valve apparatus by 2-dimensional Doppler echocardiography in rats with experimental endocarditis caused by Coxsackie B3 viruses].

Eleven neonatal cotton rats were infected with Coxsackie B3 viruses, 9 animals served as controls. The course of the disease was followed for 44 to 154 days. Electro- and phonocardiography, two-dimensional Doppler echocardiography, morphological and histological studies were performed in the experiment. All the histologically examined infected rats were found to develop myocarditis, whereas 75% of the animals had valvulitis. The total number of the afflicted values was 10, out of them the mitral, tricuspid, and pulmonary trunk valves accounted for 40, 40, and 20%, respectively. Doppler echocardiography revealed organic mitral and tricuspid insufficiencies in the outcome of valvulitis induced by Coxsackie B3 viruses due to the impairment of valvular cusp.

[Physiological valvular regurgitation in healthy persons (its prevalence, hemodynamic characteristics and differential diagnosis)].

Two-dimensional Doppler echocardiography (DECG) was employed to examine for valvular regurgitation 100 healthy subjects. Physiological valvular regurgitation (PVR) was detected in 32 of them. It was defined as isolated pulmonary, isolated tricuspid, combined tricuspid and pulmonary, mitral in 17%, 9%, 4% and 2% of the examinees, respectively. Hemodynamically, PVR was characterized by low maximal speed of the flow and minimal extension. It should be noted that similar hemodynamic DECG parameters can be registered in minimal aphonic valvular regurgitation arising in latent rheumatic and viral endocarditides. This fact must be taken into consideration when making the differential diagnosis.

[Abramov's "primary myocarditis", Fiedler's myocarditis and dilated cardiomyopathy].

After comparing the clinical and post mortem signs of myocarditis and dilated cardiomyopathy on the basis of correlating the reported data and own data on 28 patients with the appropriate descriptions by S. S. Abramov and A. Fiedler, the authors came to the conclusion that they had described two different diseases. S. S. Abramov had described dilated cardiomyopathy, whereas Fiedler acute diffuse myocarditis. The term Abramov-Fiedler myocarditis used in the Soviet literature does not correspond to the up-to-date classification of myocardial diseases. That is why it is required that these two concepts be separated to the benefit of the treatment.

[The role of Coxsackie B viruses in the etiology of dilated cardiomyopathy].

In order to establish the relationship between Coxsackie B virus infection and dilated cardiomyopathy (DCMP), 53 patients suffering from DCMP underwent serological tests. The rate of demonstration of virus-neutralizing antibodies at different titres was compared with the respective values in the previously examined 180 patients with myocarditis, 58 patients with myocardial sclerosis and 150 normal persons. In DCMP, antibodies against B2 type virus were detectable more frequently (p less than 0.001) and at higher titres (p less than 0.05) that in normal persons. Antibodies at the titres greater than 1:128 were most demonstrable in myocarditis and then at an equal rate in DCMP and focal myocardial sclerosis following Coxsackie myocarditis. The conclusion is drawn about the relationship between Coxsackie infection and DCMP as well as between DCMP and myocarditis. The reported data on the mechanisms by which myocarditis progresses to DCMP are discussed.

[Viral myocarditis (the etiologic, clinical, diagnostic and treatment problems)].

To elucidate the etiology of respiratory infection and pharyngitis associated myocarditis a serological study was made of 201 patients who were successively admitted with a clinical diagnosis of myocarditis. Coxsackie viral infection of group B, influenza A and B, para-influenza and adenoviral infection and beta-hemolytical streptococcus of group A were determined. Preceding Coxsackie infection was established in 38,3% of the patients, influenza A and B in 27.5%, adenoviral infection in 3.6% and para-influenza in 1.7%. beta-hemolytical streptococcus as the cause of myocarditis was detected in 4.9% of the patients only. In view of the viral etiology of most cases of myocarditis the authors discussed the problems of its pathogenesis, clinical course and therapy.

[Myocarditis caused by Coxsackie B viruses in adults].

Two hundred and thirty-eight patients with a clinical and electrocardiographic diagnosis of myocarditis and two control groups were examined for virus-neutralizing antibodies against Coxsackie B1-6 viruses. Serological evidence for preceding Coxsackie infection was demonstrated by 40.9% of myocarditis and in 29.3% of myopericarditis patients. Coxsackie B2 and B4 viruses were the most prevalent. The patients manifested a significant increase in the antibody titer as compared with the control group.
