Summary:

The aim of the study is to create a mathematical model of non-invasive diagnostics of coronary heart disease. Research materials include indicators of heart rate variability, time and speed characteristics of repolarization phase of electrocardiograms obtained in 111 patients with coronary heart disease and in 92 healthy individuals. As a result of the multifactor discriminant analysis decisive diagnostic rule has been worked out. The proposed method allows to detect coronary artery disease in 97.7% of cases

INFLUENCE OF SEASON PATTERN ON PREVALENCE AND SEVERITY OF ACUTE MYOCARDIAL INFARCTION, FUNCTION OF HEMOSTASIS IN PATIENTS WITH ISCHEMIC HEART DESEASE OF CLIMATE AREA OF MIDDLE VOLGA REGION

Year: 2007, volume 3 Issue: №3 Pages: 68-72
Heading: Internal Diseases Article type: Original article
Authors: O.K. Rybak, A.N. Burlaka, N.P. Ivannikova, A.P. Burlaka
Organization: Saratov Institute of Cardiology, Russia, Saratov State Medical University
Summary:

The aim of this study is to evaluate season pattern, severity and outcome of acute myocardial infarction in dependence of yearly patterns of function of hemostasis in middle Volga Region. Season pattern of prevalence myocardial infarction with winter peak was discovered, be accompanied of increase platelet aggregation, deterioration of blood viscosity, fibrinolysis depression. Most serious clinical course of summer myocardial infarction was observed with prosperity of hemostasis.

DAILY PATTERN OF ACUTE MYOCARDIAL INFARCTION IN ELDERLY AND SENILE PATIENTS OF MIDDLE VOLGA REGION

Year: 2007, volume 3 Issue: №1 Pages: 71-73
Heading: Internal Diseases Article type: Original article
Authors: O.K. Rybak, A.N. Burlaka, N.P. Ivannicova, M.E. Rakovsky, A.P. Burlaka
Organization: Saratov Institute of Cardiology, Russia
Summary:

The aim of this study is to evaluate daily patterns of acute myocardial infarction in elderly and senile patients of climate area of middle Volga Region. Daily recurrence of acute myocardial infarction was discovered in dependence of sex and age, hours of "high risk" and "prosperity" were determined.
