[Comparative analysis of mortality from acute forms of ischemic heart disease during a 15-year period in the Russian Federation and the United States and the factors influencing its formation]. / Sravnitel'nyi analiz smertnosti naseleniia ot ostrykh form ishemicheskoi bolezni serdtsa za piatnadtsatiletnii period v RF i SShA i faktorov, vliiaiushchikh na ee formirovanie.

AIM: To comparatively analyze the registered mortality rates from coronary heart disease (CHD) as a whole, as well as myocardial infarction (MI) and other acute forms of CHD during a 15-year period in the Russian Federation (RF, 2000-2014) and the United States of America (USA, 1999-2013). MATERIAL AND METHODS: Primary data were obtained from the database of the RF State Statistics Service, the World Health Organization Mortality Database, Human Mortality Database, then converted into standardized mortality rates and are presented in three age groups (30+, 30-49, and 50+ years old) in men and women separately. RESULTS: The analysis revealed a substantial excess of the registered mortality rates from CHD in the RF versus in the USA, as well as a lower incidence of MI and a higher incidence of other acute CHD forms registered as the cause of death. It also showed considerable differences in the structure of registered types of MI as the cause of mortality. CONCLUSION: The differences found in the mortality rates from CHD, MI, and other acute forms of CHD in the RF and the USA can be explained by objective (the higher prevalence of cardiovascular risk factors, the higher and earlier incidence of CHD in the RF, as well as differences in the organization of medical care and, as a result, actually higher mortality rates from CHD in Russia) and subjective (differences in approaches to statistically developing a population-based mortality rate, as well as defects in filling out the medical documents and coding the causes of death) factors.

[The Modern Aspects of Diagnosis Formulation and Statistical Recording of Myocardial Infarction].

The modern principles of myocardial infarction diagnosis formulation, recording, and statistical coding are discussed in the article. It contains material on terminology, clinical classifications and practical aspects of use of 10th revision of the International statistical classification of diseases and related health problems.

[THE QUALITY OF EXAMINATION OF PATIENTS WITH ARTERIAL HYPERTENSION BASED AT OUTPATIENT FACILITIES].

AIM: To analyze the quality of application of diagnostic methods in patients with arterial hypertension (AH) based at outpatient facilities in comparison with equipments of national clinical recommendations. MATERIALS AND METHODS: The study was conducted in the framework of the outpatient registry of cardiovascular diseases (REKVAZA). It included analysis of outpatient medical cards of 2850 patients with AH examined in two municipal polyclinics. Men accounted for 27.8% of the total. Patients with associated clinical conditions for 79.6%. Age median (interquartile range) for men and women was 64.8 (56.8; 74.8) and 70.6 (60.1; 77.6) years respectively. RESULTS: It was shown that the scope of real physical examination (measurements of height, mass, waist circumference, BMI) was below the target level (p < 0.001). Results of complete blood cell count for the previous 12 months could be found only in 71.7% of the cards, data on blood glucose level in 61/7%, total cholesterol in 42.7%, creatinine in 45.4%, results of ECG in 59.9%, echoCG in 9.5%, 24hr AP monitoring in 0.3%. Instrumental and laboratory studies were more often performed in patients with associated clinical conditions (p < 0.05). CONCLUSION: This study revealed poor quality of examination (physical, Instrumental and laboratory) of patients with arterial hypertension based at outpatient facilities.

[Autopsy study in the analysis of cardiovascular mortality].

The frequency of using autopsy to verify the cardiovascular causes of death was studied in typical regions of Russia. One thousand and sixty deaths from circulatory system diseases were analyzed among a representative sample of 285,736 subjects. Death occurred outside health care facilities in 88% of the analyzed cases; nevertheless, autopsy was made only in 28.3%. Moreover, autopsy was carried out in all cases of less than 40-year-old males and less than 50-year-old females who had died from suspected cardiovascular diseases. The proportion of notified cardiovascular mortality increased in the structure of overall mortality and the rate of autopsy-verified diagnosis decreased with advanced age. To obtain valid information on cardiovascular mortality rates is limited due to low autopsy rates primarily in cases of death outside health care facilities, particularly among elderly and senile persons, despite the fact that it is these fatal cases that constitute the bulk of registered cardiovascular mortality.

[The topical issues of the terminology, classification, and statistics of acute forms of ischemic heart disease].

The paper discusses the problems in the formation of statistical information on acute forms of coronary heart disease (IHD) in Russia and possible ways of their solution. Among other problems, there is the detection and notification of cases of sudden coronary death as an independent nosological entity that belongs to the acute forms of IHD. The terminology and classification of the acute forms of IHD, which affect the formation of statistical data, are considered. The consequences of underestimates of the role of a postmortem study, as the most important postmortem diagnostic method, in modern practical health care are discussed. The paper is largely debatable and intended for a wide circle of readers in order to attract their attention to the detection and notification of the acute forms of IHD in clinical practice, especially in cases of death from acute IHD in the prehospital stage.

[Detectability of acute forms of coronary heart disease in real clinical practice].

The study was designed to evaluate the frequency of inapparent and/or unrecorded cases of acute coronary heart disease (CHD) and its influence on overall estimates of CHD mortality and morbidity. A specially developed algorithm was used to identify unrecorded cases in official medical documentation concerning 285,736 subjects. Their fraction was found to be 20.78 and 24.48% among men and women respectively. 89.43% of them died from acute CHD. Addition of the newly identified cases to official statistics increased overall CHD morbidity rates by 26.24 and 32.41% for men and women and mortality rates by 2.13 and 2.28 times respectively. These data indicate that acute CHD is poorly diagnosed in routine clinical practice and the real CHD mortality rate is grossly underestimated.
