[Effects of laser therapy in patients with functional class II-IV effort angina (using instrumental techniques of the study)].

Infrared laser therapy using an arsenide-gallium laser was used in 54 patients aged 30-75 years who suffered from coronary heart disease. A positive clinical effect was achieved in 47 (87%) of 54 patients, as evidenced by the reduced number of nitroglycerin tablets used and improved bicycle ergometric, echo- and electrocardiographic parameters in the patients.

[Hormonal aspects of the pathogenesis of cardiac arrhythmias in patients with hypertrophic cardiomyopathy].

Radioimmunoassay was used to measure thyroid, somatotropic, parathyroid hormones and cyclic nucleotides in 40 patients with hypertrophic cardiomyopathy and 14 with hypertensive disease concurrent with asymmetrical myocardial hypertrophy. In the patients with hypertrophic cardiomyopathy, the mean blood concentration of thyroid, somatotropic, parathyroid hormones and cyclic nucleotides was generally within the normal ranges and similar to that in hypertensive patients with apparently healthy individuals. The patients with hypertrophic cardiomyopathy concurrent with supraventricular arrhythmias exhibited higher blood levels of total and free thyroxine and thyroxine/thyroxine-bound globulin ration than did patients without arrhythmias.

[Changes in vascular reactivity during the noradrenaline test in patients with hypertension].

To study vascular responses and to choose a differential therapy, 51 patients with hypertensive disease underwent a pressor test combined with intravenous epinephrine. The test revealed two types of blood pressure control. In type I responses (normotensive responses), there was a good antihypertensive effect shown by beta-adrenoblockers and/or a course of physical trainings.

[Changes in the hemostatic system in patients with ischemic heart disease after isovolemic hemodilution].

To specify indications for isovolumic hemodilution, hemostatic parameters (fibrinogen, soluble fibrin, fibrin decomposition products, platelet aggregation, thromboelastograms) were compared with clinical manifestations of coronary heart diseases (CHD) and coronarographic and bicycle-ergometric findings in 41 coronary patients. The increased blood viscosity syndrome was found in 63% of the patients. Isovolumic hemodilution was performed to control the detected disorders in 17 patients.
