“…Так, по данным Timonin S, et al разные подходы к определению ППС приводят к тому, что ИМ зарегистрирован в качестве ППС в РФ в 12%, а в Норвегии -в 63% смертей из группы ИБС [2]. Выявленное в нашем исследовании значительное снижение СРСКС от повторного ИМ, при значительно меньших колебаниях СКС от острого ИМ, вероятно, связанно именно с расхождением экспертных мнений в вопросе, какие именно случаи следует учитывать как повторный ИМ 1 .…”

“…Однако роль и вклад сочетанной патологии при оценке смертности не учитывается, т.к. учет и анализ причин смерти осуществляется на основании первоначальной причины смерти (ППС) [1]. На указанную ППС оказывает влияние множество факторов, включая то, что в разных странах имеют место разные подходы к определению ППС и организации кодирования причин смерти.…”

Aim. To analyze mortality from cardiovascular diseases (CVDs) and diseases associated with cognitive impairment (CI) in the regions of the Russian Federation.Material and methods. We analyzed Rosstat mortality data in 82 Russian regions in mid-year population in one-year age groups for 2019-2021. Eleven groups of causes have been formed, standardized mortality rates (SMRs), average regional SMRs, and their changes over time was assessed.Results. In total, SMRs from CVD and CI increased from 551,4±84,9 in 2019 to 622,6±98,5 per 100 thousand population in 2020 and decreased in 2021 to 612,6±106 per 100 thousand population. However, its proportion in all-cause mortality decreased by almost 10% (46,97±4,6 in 2021 and 55,98±4,6% in 2019). The growth of SMRs from year to year was noted in 30 regions; in other regions, unstable changes were noted. The proportion of CVD causes from all-cause mortality was 30,5±5,8% in 2019, 29,1±5,7% in 2020 and 25,95±5,56% in 2021 (p<0,0001). The largest SMRs and their proportion in the mortality structure are in group 1 (chronic coronary artery disease (CAD) — an average of 17,8±5,8% over 3 years) and group 6 (causes with unclear criteria for the disease, but associated with CI — 13,9±5,9%). The contribution of the second (acute coronary artery disease — 4,6±2,8%), the third (defects, cardiopathies, endo- and myocarditis — 4,8±2,7%) and the fifth (stroke — 6,1±1,7%) groups of causes are much smaller. The sixth place in terms of SMRs and contribution to all-cause mortality is occupied by alcohol-associated causes (1,8±1,1%). The proportion of other causes (hypertension, Alzheimer’s disease, Parkinson’s disease, other mental disorders) is small.Conclusion. When developing and implementing programs aimed at reducing mortality, results obtained should be taken into account. Significant regional differences in the rate and changes of SMRs over time indicate the need to unify the criteria for the underlying cause of death, especially in multimorbid patients.

Background Arterial stiffness is a degenerative modification of the arterial wall significantly influencing normal aging, longevity, and vascular health. Hypertension is a major risk factor for the development of arterial stiffness, which can lead to changes in cerebral perfusion and cognitive dysfunction. This, in turn, can increase the risk of cognitive decline. Pulse wave velocity (PWV) is an established gold standard for measuring arterial stiffness. Studies have shown that individuals with hypertension and elevated PWV are more likely to experience worse cognitive decline compared to those with either condition alone. The current literature, however, demonstrates controversial results. The aim of this article is to review the most recent published studies linking arterial stiffness to cognitive function in individuals with arterial hypertension. Methods We conducted a systematic review following the Cochrane protocol that was registered through the NIHR PROSPERO system. The PRISMA 2020 guidelines were used for reporting the systematic review. PubMed, Embase, Web of Science, CINAHL, and Cochrane databases were searched for relevant publications from early June to the end of December 2022. This review includes publications with a sample size of at least 500 participants older than 45 years. Screening of abstracts and full-text review of chosen articles were carried out through the Covidence. Results A total of 434 articles were selected for the full-text review. Twenty-four longitudinal studies and four cross-sectional designs that met the inclusion criteria were selected for the comparisons. The total sample size for these studies was 56,946 individuals. Twenty-seven studies (95%) demonstrated a significant association between arterial stiffness and cognitive dysfunction in hypertensive individuals. One study reported an association between stiffness and cognition independent of blood pressure (5% of the total population). Conclusion The results of this systematic review showed that arterial hypertension is one of the most important factors linking arterial stiffness to cognitive disorders. Pulse wave velocity was shown to be a strong measure associated with cognitive decline in aging individuals with chronically elevated blood pressure. Early screening for arterial stiffness, hypertension treatment, and effective prevention of cerebrovascular disease are imperative for cognitive health. NIHR PROSPERO registry ID: CRD 42022379887

In recent years, researchers have noted an increase in mortality from neurodegenerative diseases and a decrease in mortality from strokes. There have been no studies comparing mortality from these causes in the regions of the Russian Federation.Aim: comparative analysis of regional (age-) standardized death rate (SDR) among men and women from cerebrovascular diseases (CVD) and nervous system diseases (NSD) in 2013 and 2022 and discussion of factors influencing SDR.Materials and methods. Rosstat data obtained upon request were used. SDR was calculated using software (state registration number of computer program 216661114) using the European Standard Population using the direct standardization method per 100 thousand population; The average regional SDR values were calculated for the class of NSD and individual groups from this class, CVB (codes I60–69).Results. A decrease in the regional average SDR from CVD was revealed among men (218.09 ± 60.81 in 2013 and 159.41 ± 51.20 per 100 thousand people in 2022) and women (144.30 ± 39.33 and 103.51 ± 32.63 respectively) and the increase in SDR from LBP (19.77 ± 17.70 and 65.99 ± 56.67 for men, 10.99 ± 11.32 and 52.81 ± 46.13 for women). Only in 4 regions was there a decrease in SDR from both NSD and CVD in both men and women. The dispersion of regional SDRs from NSD and CVB in 2022 compared to 2013 increased by more than 10 times, which indicates a significant and growing regional variability of indicators. In the stroke group, the most significant decrease occurred from “Stroke not specified as hemorrhage or infarction” (code I64). The regional average contribution of acute stroke (codes I60–64) to the SCS from NSD and CVB (in total) decreased (in 2013 among women 51.57 ± 16.26 %, in 2022 33.96 ± 14.95 %; among men 54.0 ± 15.01 and 39.82 ± 14.26 respectively). Alzheimer’s disease makes a negligible contribution to mortality; In men in certain regions, alcohol-associated LBP is significant.Conclusions. Significant regional variability of SDR from individual groups of causes and a general trend towards a decrease in SDR from CVD and an increase in SDR from NSD were revealed, which is due to many factors. To eliminate the influence of different approaches to determining the cause of death, a unified protocol of criteria for their establishment is necessary.
