The present research aims at comprehensive analysis to determine the effectiveness of cardiac surgery in patients in the acute period of myocardial infarction in comparison with patients who received drug treatment. A comparative assessment of the level of hospital mortality was carried out in the groups of patients of senior working age, elderly and old age, dividing them into patients who received cardiac surgery (main group) and drug treatment (comparison group). Among the patients of working age, 284 were assigned to the main group and 272 to the comparison group; among the patients of elderly age, 104 were assigned to the main group and 363 to the comparison group; and among the patients of old age, there were 9 patients in the main group and 235 patients in the comparison group. For reliable difference between the compared indicators, the authors determined the relative risk of socio-hygienic factors in terms of mortality rate and the significant limit of mortality formation, taking into account that the factor the relative risk of which is more than one is significant. The significant difference in mortality in hospital between patients who received high-tech medical services (HTMS) and the group of patients who did not undergo such high-tech heart surgery was found only in the elderly patients (65-74 years old), p = 0.002 (chi-square). The number of deaths in hospital from myocardial infarction in the main group increases with age. Mathematical modeling showed that the level of hospital mortality is also influenced by the provision of the hospital with qualified cardiologists, specialized bed and special medical equipment.
In the present work presents the results of scientific substantiation of medico-social preventive the disease of the digestive system at school students conducted on the basis of the prediction table. The development of a prognostic matrix for predicting the occurrence and development of diseases of the digestive system in schoolchildren was carried out according to a comprehensive socio-hygienic study of schoolchildren and the study of the prevalence of diseases of the digestive system according to medical examinations among schoolchildren. The influence of socio-hygienic and medicobiological factors on the occurrence and development of digestive diseases in schoolchildren was studied. To do this, we have compiled a special map of the study of socio-hygienic and biomedical factors for the formation of diseases of the digestive system, which includes 28 factors and 84 of their gradations. It was calculated all the parameters for the preparation of a prognostic matrix to assess the occurrence of diseases of the digestive system in schoolchildren by socio-hygienic and medico-biological risk factors. Taking into account the great importance of the prognostic coefficient for Pediatrics and gastroenterology, it was developed ready-made threshold values of the prognostic index that characterize the probability of the risk of digestive diseases in schoolchildren.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
