[The systematic position of Hymenolepididae (Cestoda) from Australian marsupials]. / O sistematicheskom polozhenii gimenolepidid (Cestoda) iz avstraliiskikh sumchatykh.

A review of Hymenolepididae from Australian Marsupialia is given. These cestodes are transmitted out of the genus Hymenolepis, into which they were previously included. 3 species of them are transmitted to the genus Rodentolepis, and 7 species are arranged as a new genus Potorolepis. The diagnosis of Potorolepis and a list of species included are given. Possible phylogenetic relations of the genus Potorolepis with nearest groups of cestodes are discussed.

[The importance of an early stress test in patients with myocardial infarct and heart failure in the acute period of the disease]. / Znachenie rannei nagruzochnoi proby u bol'nykh infarktom miokarda s serdechnoi nedostatochnost'iu v ostrom periode zabolevaniia.

The mechanisms of acute myocardial infarction depend on the site of myocardial infarction (MI). In anterior MI, the main factor is a large area of injury; in inferior MI, of importance is dysfunction of the papillary muscles and multiple lesions of the coronary artery in addition to the above factor. The site, the area of injury and the status of the coronary bed influence the rate, character and prognostic value of early load test criteria and contractile function of the left ventricle. In anterior MI, elevation of the ST segment is the most frequent criterion; in inferior MI, its depression. Their combination with other criteria for test discontinuation point to multiple lesions of the coronary artery. In patients with anterior MI, the ejection fraction of the left ventricle amounting to 40%, inadequate growth of AP, anginous pain and the T dominant elevation of the ST segment are unfavourable predictors, allowing the patients to be differentiated in accordance with the risk of postinfarction complications.

[Interrelations between obstructive changes in the coronary arteries and clinical manifestations of heart failure in patients after myocardial infarction]. / Vzaimozavisimost' obstruktivnykh izmenenii koronarnykh arterii i klinicheskikh proiavlenii serdechnoi nedostatochnosti u bol'nykh, perenesshikh infarkt miokarda.

The study was undertaken to examine clinical and angiographic signs in 154 patients with prior myocardial infarction. There was a relationship between the left ventricular performance and heart failure stages and the number of diseased left ventricular segments and heart failure stages. With an increase in the number of diseased left ventricular segments, cardiac contractility decreased. Severe stages of heart failure were observed in the diseased channel of the infarct-related anterior interventricular branch and in its occlusion. The stages of heart failure were unassociated with the number of diseased coronary arteries, and the presence or absence of collaterals. There were more frequently eccentric stenoses of type II and/or irregular shape in severe heart failure groups.

[Prognostic significance of disorders of regional left-ventricular contractility detected in the subacute period of myocardial infarction]. / Prognosticheskoe znachenie narushenii regionarnoi sokratimosti levogo zheludochka, opredeliaemykh v podostrom periode infarkta miokarda.

The predictive value of left ventricular contractility index, lesion extent, ejection fraction was examined from sector scanning data in 107 able-bodied males with primary transmural myocardial infarction (MI) complicated by left ventricular aneurysm in the acute period (in 28 patients with anterior MI) and heart failure (in 23 patients with inferior MI). The findings suggest that the severity of regional contractility disorders is associated with the location of myocardial infarction and the state of the coronary bed. The significant lesion extent and multiplicity in the coronary arteries showed a high risk for postinfarction events. On the contrary, the lack of severe regional contractility disorders and isolated coronary lesion were indicative of good prognosis.

[Clinical manifestations of ischemic heart disease in the subacute period of myocardial infarction and post-infarct cardiosclerosis depending on the status of coronary arteries]. / Osobennosti klinicheskikh proiavlenii ishemicheskoi bolezni serdtsa v podostroi stadii infarkta miokarda i postinfarktnogo kardioskleroza v zavisimosti ot sostoianiia koronarnykh arterii.

Multifactor discriminant analysis was used on a computer to examine 100 patients with myocardial infarction in the subacute period (at week 4 of the disease onset) and 76 in the postinfarction period (at months 2-120 of postinfarction). A complex of clinical and coronary signs was defined, which differentiated patients with subacute myocardial infarction and postinfarct cardiosclerosis, as well as those with postinfarct stable and progressive angina pectoris.

[The value of early exercise testing in patients with myocardial infarction complicated by evolving left ventricular aneurysm]. / Znachenie rannego nagruzochnogo tecta y bol'nykh infarktom miokarda, oslozhennym razvitiem anevrizmy levogo zheludochka.

The values of an early exercise test limited by criteria for test termination were compared with coronaro- and ventriculographic measurements made 2-3 days after the test in 51 males of working age who suffered from transmural myocardial infarction complicated by local aneurysm in 12 cases and by overall left ventricular aneurysm in 39. The exercise test performed in the early periods was found to substantially increased its sensitivity. The isolated ST-dominant segment elevation in patients with local aneurysm and isolated coronary artery lesion indicated that the patients had a favourable prognosis. On the contrary, the combination of two criteria or more of a positive test in patients with global aneurysm and multivessel disease suggests that the patients with temporary disability should be followed up. The presence of T-dominant ST-segment elevation, anginal pain concurrent with an inadequate BP elevation shows that there is a high risk for postinfarction complications.

[Features of clinical manifestations of intermediate coronary syndrome in relation to the status of the coronary bed]. / Osobennosti klinicheskikh proiavlenii promezhutochnogo koronarnogo sindroma v zavisimosti ot sostoianiia koronarnogo rusla.

Uni- and multifactorial analyses of clinical and angiographic findings were made in 32 patients with coronary heart disease concurrent with the intermediate coronary syndrome and 34 patients with progressive angina pectoris. A complex of clinical and angiographic signs was defined, which enabled these groups of patients to be differentiated. Exercise tolerance was the same in the two groups and related to the severity of coronary artery lesions. The efficacy of the antianginal therapy depended on the angiographic morphology of occlusive changes in the coronary bed and it was less in patients with Type II eccentric stenosis.

[Development of left-ventricular aneurysm in relation to the status of the coronary bed in patients with a history of myocardial infarction]. / Razvitie anevrizmy levogo zheludochka serdtsa v zavisimosti ot sostoianiia koronarnogo rusla u bol'nykh, perenesshikh infarkt miokarda.

The study was undertaken to examine 270 patients with a history of myocardial infarction. Its purpose was to reveal a relationship between the ischemic signs of cardiac aneurysm and the status of coronary arteries. The findings suggested that left ventricular aneurysm was greatly due to severe obstruction of the infarct-related right intraventricular branch of a coronary artery.

[Characteristics of the clinical manifestations of stenocardia in patients with ischemic heart disease, without myocardial infarct, in relation to the state of the coronary bed]. / Osobennosti klinicheskikh proiavlenii stenokardii u bol'nykh ishemicheskoi bolezn'iu serdtsa, ne perenesshikh infarkt miokarda, v zavisimosti ot sostoianiia koronarnogo rusla.

Mono- and multifactorial discriminant analyses aided by computer were used in 106 patients with coronary disease to compare the clinical and angiographic findings common to different manifestations of angina pectoris. The relationship was discovered between the clinical form of angina pectoris and the gravity of lesions of the coronary artery. Intracardiac hemodynamics and left ventricular contractility at rest did not differ whatever the patients' group. According to the bicycle ergometry test, the physical exercise tolerance was lower in patients with progressive angina pectoris and depended on the gravity of coronary artery lesions. The outcome of the clinical manifestations of angina pectoris during observation at hospital was mainly influenced by the natural course of coronary disease, primarily stipulated by obstruction in the coronary arteries. Using the multifactorial discriminant analysis aided by computer, the classifying signs were outlined, making it possible to differentiate between the groups of angina pectoris patients depending on the duration of angina pectoris attacks (in minutes), irradiation of pain to the shoulder or to both arms, T wave inversion on the ECG, and the gravity of coronary artery obstruction. The given signs enable one to recognize patients with destabilization of the clinical course of angina pectoris.

[Effect of physical training with reference to anaerobic threshold on the indicators of exercise tolerance and restoration of work capacity in patients after myocardial infarction]. / Vliianie fizicheskikh trenirovok s uchetom anaérobnogo poroga na pokazateli tolerantnosti i vosstanovlenie trudosposobnosti u bo'lnykh, perenesshikh infarkt miokarda.

In patients who had sustained myocardial infarction including that of complicated history, the anaerobic threshold was defined to choose the optimum intensity of physical training. The latter were also examined for effects on exercise tolerance. It was ascertained that measuring physical exercise by heart rate at the level of the anaerobic threshold made it possible to choose the optimal conditions for the aerobic supply of metabolic demands during physical training. Applying physical training under aerobic conditions greatly increases exercise tolerance, prevents recurrent myocardial infarctions and plays an important role in the secondary prevention of coronary heart disease.

[Prognostic significance of the area of myocardial lesion and the status of the coronary bed during restoration of work capacity in patients with a complicated course of acute myocardial infarction]. / Prognosticheskoe znachenie ploshchadi porazheniia miokarda i sostoianiia koronarnogo rusla pri vosstanovlenii trudosposobnosti bol'nykh s oslozhnennym techeniem ostrogo perioda infarkta miokarda.

The effect of heart failure and acute left-ventricular aneurysm on the recovery of working capacity was assessed with reference to the size of necrotic focus and the extent of coronary arterial involvement in 117 patients with acute myocardial infarction. The size of necrotic focus and magnitude of coronary arterial affection were shown to be the principal determinants of heart failure in acute myocardial infarction. The presence of heart failure and acute left-ventricular aneurysm in combination with multiple coronary-arterial lesions is an adverse predictive sign in the assessment of the severity of acute myocardial infarction and the recovery of patients' working capacity. On the contrary, the presence of a local aneurysm in combination with an isolated coronary-arterial lesion should not be regarded as an unequivocal indicator of disability.
