[Prediction of Subclinical Carotid Atherosclerosis With Parameters of Negative for Ischemia Exercise Testing].

Aim: to elucidate relationship between parameters of negative ischemic stress test and subclinical atherosclerosis of carotid arteries.

Material And Methods: Electrocardiographic stress test on treadmill and ultrasound study of carotid arteries (CA) were carried out in 204 patients (100 women and 104 men, mean age 54.16±8.

[Revascularization or conservative strategy in patients with stable coronary heart disease: a contemporary view].

Choice between revascularization and conservative strategy in patients with stable coronary heart disease (CHD) is an important clinical problem, especially when the need for revascularization is not urged by severe ischemic symptoms. Revascularization aimed to improve prognosis is most justified in patients having high risk, based both on results of coronary angiography and functional tests. In the opinion of many experts, the high-risk features at stress-test is a key to identify patients in whom revascularization is most required among persons with high-risk coronary anatomy, as well as to select candidates for invasive treatment among patients with more favorable variants of coronary lesions.

[Individual coronary heart disease risk prediction as part of primary prevention].

Correction of traditional risk factors (RF) at the population level resulted in considerable progress in prevention of coronary heart disease (CHD) in many countries. At the same time existing approaches to individual prediction of cardiovascular diseases based on the analysis of traditional RF and global risk scoring are in some cases ineffective. This problem most notably relates to a large group of persons with low calculated risk (young patients, persons without multiple RF, women) which accounts for the greatest in absolute numbers quantity of primary cardiovascular events.

[Prediction of left ventricular remodeling after acute myocardial infarction].

Prediction of adverse left ventricular remodeling after acute myocardial infarction (AMI) may have important clinical implications. In this study, we evaluated the incidence of unfavorable changes of left ventricular volumes and ejection fraction after AMI. The ability of several cardiac markers, electrocardiographic and echocardiographic (including tissue Doppler) variables to predict adverse remodeling was demonstrated.

[Advanced age as a risk factor for heart failure after acute myocardial infarction].

Heart failure (HF) is one of the most unfavorable consequences of the acute myocardial infarction (AMI), resulting in increased hospitalization level and mortality. The patients of advanced age constitute the major part among patients with HF due to AMI. In 123 patients a number of variables of the acute phase were investigated as potential predictors of developing HF within 12 months after AMI and the role of age was assessed.

[Effect of ritmilen on myocardial refractility and cardiac impulse conduction in patients with paroxysmal tachycardia].

By choosing antiarrhythmic therapy, ritmilen, 3 mg/kg, was given to 30 patients with atrial, atrioventricular, reciprocal and ventricular tachycardias. The agent was found to have the highest effect on atrial myocardial refractoriness in patients with atrial tachycardias and on ventricular refractoriness in patients with ventricular tachycardias (longer effective and functional refractory periods). Intraventricular pathways are the major site of ritmilen's effect on anterograde conduction.

[Myocardial refractory changes after single intravenous administration of cordarone (electrophysiologic study of the heart)].

In 29 patients with cardiac arrhythmias, refractory periods (RP) of the atrium, atrioventricular node and ventricle were defined before and after intravenous administration of cordarone in a dose of 5 mg/kg body weight. The effective RP (ERP) of the atrio-ventricular node showed the most profound changes: in 73% of the patients, the increase was 22.8% as compared to the pretreatment value.

[Echo- and electrocardiographic signs of different forms of hypertrophic cardiomyopathy].

Twenty-six patients with idiopathic and secondary hypertrophic cardiomyopathies were examined. The diagnostic value of echo- and electrocardiographic signs of hypertrophic cardiomyopathy is discussed, the more important among those being the thickness and shape of the interventricular septum, anterosystolic movement of the anterior cusp of the mitral valve, electrocardiographic evidence of left-ventricular hypertrophy and left-atrial changes, abnormal Q waves.

[Treatment of paroxysmal forms of auricular fibrillation and atrial flutter in a cardiological hospital].

The results of treatment of paroxysmal forms of atrial fibrillation and flutter are analysed in a group of 503 patients with attacks lasting up to 3 weeks. The sinus rhythm was restored in 84.7% of patients, in only 3% of cases was electro-impulse therapy resorted to.

[Importance of recording the intracardiac electrical potentials in the diagnosis and treatment of complex arrhythmias in an emergency care center].

The indications for the catheterization of the heart and the recording of cavity electric potentials at the emergency aid centre are being considered. The possibilities have been studied of the electrography of the conductive system of the heart for differentiation of supraventricular paroxysmal tachycardias with blocks of pedicles of the His' bundle and ventricular paroxysmal tachycardias, and of irregular ventricular tachycardia and attacks of auricular fibrillation with pedicle blocks, and for the determination of the level of the atrioventricular blocks.
