FUNCTIONAL STATE OF THE CARDIOVASCULAR SYSTEM IN PATIENTS WITH ACUTE CORONARY SYNDROME AND TYPES OF BEHAVIORAL ACTIVITY A, AB, B

Aim. To study the effect of behavioral activity type on the sympathetic nervous system in patients with acute coronary syndrome - ACS (unstable angina and acute myocardial infarction). Materials and methods. The study included 100 patients with ACS, who were subsequently divided into groups according to the main disease - acute myocardial infarction and unstable angina. The median age was 62.09±5.46 years, therapy according to the underlying disease. All patients had anamnesis of previous and concomitant diseases, anthropometric measurements, physical examination, and observation during the next 24 months after inclusion in the study. In dynamics he carried out daily monitoring of electrocardiogramm, daily monitoring of blood pressure (BP), echocardiography. Diagnosis of types of behavioral activity was carried out using the test method "type of behavioral activity" developed on the basis of the questionnaire Jenkins Activity Survey (JAS), published in 1974 by C. David Jenkins, the Russian-language adaptation was performed in Bekhterev Psychoneurological Research Institute (L.I. Wasserman, N.V. Gumenyuk). Results. Patients with ACS and behavioral type A activity demonstrate increased activity of the sympathetic nervous system in the form of a higher level of systolic and diastolic BP, high variability of BP, increased rate of BP rise in the morning, a higher heart rate during the day in comparison with the types of behavior of AB and B, which can be considered as an unfavorable prognostic predictor of cardiovascular complications.
