Analysis of mortality among patients suffering from heart failure, using the example of a megalopolis

The medical documentation (n = 146912) introduced into the system “Regional fragment of the unified state information system in the field of healthcare” of Saint Petersburg for 2019–2021 was analyzed. To evaluate the mortality of patients due to heart failure, all deceased patients from 2019 to 2021 in Saint Petersburg (n = 192133) were taken as a basis, and based on a thorough study of medical documentation, patients who died from cardiovascular diseases and because of heart failure were singled out separately. The total mortality from all causes in Saint Petersburg in 2019 was 53025 people; in 2020, 66468 people; and in 2021, 72640 people. The analysis of mortality due to cardiovascular diseases from 2019 to 2021 showed an upward trend of 20.1% over the 3-year period of data analysis. When analyzing the prevalence of heart failure among deceased patients, an increase of 129.4% was noted over this period. The obtained results of the prevalence, mortality, and mortality of patients due to heart failure on the example of a megalopolis are the most relevant at the current time; they indicate a steady increase in the number of patients suffering from heart failure with an increase in the burden on the city’s healthcare system. Simultaneously, there is insufficient continuity in the provision of medical care to patients suffering from heart failure, which is because of not only a shortage of medical personnel at all stages of medical care but also insufficient compliance of patients who either do not want to be treated or cannot continue treatment. Moreover, a significant disconnect was found in the continuity of medical care at the stages of pre-hospital and hospital treatment, as well as further outpatient follow-up of patients suffering from heart failure in the metropolis. All this leads to a significant increase in the mortality and mortality of patients suffering from heart failure, despite all the existing modern effective drug therapies. It appears critical to create a unified register platform for recording patients with heart failure, which will allow for a more accurate understanding of epidemiological aspects, the solution of which will improve the quality of medical care, identify the need for the crucial medicines, and reduce mortality, and mortality rates due to heart failure.
