[The prehospital diagnosis of unstable angina pectoris in case of a mid-urbanized town of West Siberia: results of a population-based study].

Aim: To assess the prehospital diagnosis of unstable angina pectoris (UAP) in the population of a mid-urbanized town in West Siberia.

Subjects And Methods: The study was conducted using the WHO epidemiological program "The acute myocardial infarction registry" that had been implemented in Tomsk since 1984. All the registered patients aged 20 to 70 years who had been diagnosed as having unstable (progressive) angina pectoris before admission to hospital and after its discharge were examined.

[Gender-related peculiarities of unstable angina at the population level].

Comparative analysis of short- and long-term prognosis of unstable angina in working-age male and female residents of the city of Tomsk is presented. Women are shown to have more favourable short- and long-term prognosis. Diabetes mellitus and previous myocardial infarction are considered to be the main factors contributing to unstable angina in women and men respectively.

[Unstable angina pectoris: outcomes of acute period and determinative factors].

Aim: To follow up for 28 days outcomes of unstable angina (UA) and to determine factors affecting the disease course and negative potential of these factors.

Material And Methods: Basing on UA clinical manifestations, 1477 patients aged 20-70 years observed in Tomsk in 2003-2004 were divided into 4 groups: group 1--patients with angina of new onset; group 2--patients with more frequent angina attacks; group 3--patients with more frequent and more severe angina attacks (longer, more painful, attacks at rest, less effective arrest with nitroglycerin); group 4--20 min and longer anginal attacks).

Results: On the disease day 29 UA stabilization was achieved in 1096 (74.

[The effects of various factors on long-term outcomes of non-stable stenocardia].

The article presents the results of one-year observation of 472 patients who experienced non-stable stenocardia in 2003-2004. During this period, exacerbation of coronary artery disease with or without acute coronary catastrophe was noted in every third patient. Thirty-three cases of acute coronary pathology were registered.

[Clinical and age-gender structure of unstable angina pectoris in conditions of moderately urbanized city in the West Siberia].

Aim: To analyse age-gender composition of patients and clinical course of unstable angina.

Material And Methods: The examination covered 2139 (77.5%) patients who had prehospital and discharge diagnosis unstable angina pectoris.

[Early outcomes of instable angina].

Analysis of early outcomes of instable angina (IA) and the clarification of prognostic factors are no doubt very important in terms of rational organization of pre-hospital diagnostic and treatment. The aim of the study was to evaluate early outcomes of instable angina in residents of Tomsk within a period of 2 years. The subjects, 2,139 patients, were examined, and the diagnosis was confirmed in 1,477 (775%) of them, among whom there were 926 (62.

[Long-term outcomes of acute myocardial infarction in Tomsk].

The paper presents the results of long-term (1- and 5-year) outcomes of acute myocardial infarction (AMI) in Tomsk patients who experienced this disease in 1997. The study was based on the data of the "Acute myocardial infarction register" and the computer-aided information system--the "Outpatient register of CHD patients". A total of 605 out of 975 patients with acute AMI (within the first 28 days) survived in 1997.

[Acute myocardial infarction onset, course and short-term outcome in men and women].

Specific features of acute myocardial infarction (AMI) onset and course, short-term outcome and its causative factors have been analysed for women and men by the data from Register of Acute Myocardial Infarction of the city of Tomsk for 1994-1998 (a total of 3717 cases). It is shown that AMI men die largely of cardiogenic shock (CS), congestive heart disease (CHD) and cardiac arrhythmia. Death of AMI women was caused primarily by CS, CHD and rupture of the myocardium.

[Acute coronary events in female residents of Tomsk. Results of 5-year observation (1994-1998)].

Aim: To study epidemiology of acute coronary conditions (ACC) including acute myocardial infarction (AMI) and acute coronary failure (ACF) among female population of Tomsk aged over 20 years and trends for 5 years.

Material And Methods: 1919 ACC episodes were compared in the women: 1616(84.2%) cases of AMI and 303(15.

[The possibilities of using ambulatory stress echocardiography with transesophageal atrial stimulation].

Stress echocardiography (duplex regimen echocardiography combined with transesophageal pacing) was performed outpatiently in 64 subjects. Among them there were patients with verified angina of effort and ischemic heart disease suspects. The test reached diagnostic criteria in 85% of the examinees.

[Silent myocardial ischemia in patients with different clinical forms of IHD].

70 IHD patients underwent ambulatory Holter ECG monitoring two times. Out of 357 episodes of transitory ischemia registered in the course of exercise and presenting primarily as ST depression the proportion of silent episodes reached 75.6%.
