In the first stage, we determined the prevalence of myocardial infarction among all respondents in 2003 and 2023. In the second stage, we compared the frequency of arterial hypertension, diabetes mellitus, stroke, smoking, and obesity (body mass index ≥30 kg/m²) between respondents with and without a history of myocardial infarction in both years.</p> <p><bold>RESULTS:</bold><bold><italic> </italic></bold>The mean age of respondents was 45.0 ± 17.8 years in 2003 and 50.7 ± 17.1 years in 2023 (<italic>p</italic> &lt; 0.001). The prevalence of self-reported myocardial infarction was 2.7% in 2003 and 2.2% in 2023 (<italic>p</italic> &lt; 0.01). The frequency of self-reported myocardial infarction differed between 2003 and 2023 across three age groups by sex. Among men under 45 years, the difference was significant (<italic>p</italic> = 0.01), but not among women (<italic>p</italic> = 0.5). In the 45–60 age group, the difference was significant for both men (<italic>p</italic> = 0.001) and women (<italic>p</italic> = 0.014). Similarly, in the over-60 group, the difference was significant for men (<italic>p</italic> = 0.009) and women (<italic>p</italic> = 0.049). Among respondents without myocardial infarction over 60 years, smoking prevalence increased slightly (from 13.5% to 14.5%); in the 45–60 group, the decline in smoking was marginal (from 34.6% to 32.8%).</p> <p><bold>CONCLUSION:</bold><bold><italic> </italic></bold>The results indicate a decrease in myocardial infarction prevalence among both men and women, alongside an increase in mean age, diabetes prevalence, and stroke history among respondents with myocardial infarction.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold><bold> </bold>Учитывая мировую тенденцию к изменению клинического портрета современного пациента, имеющего в анамнезе инфаркт миокарда, мы ограничились определением распространённости инфаркта миокарда среди репрезентативной выборки населения во временных точках 2003 г. и 2023 г.</p> <p><bold>Цель.</bold><bold> </bold>Изучение распространённости инфаркта миокарда и сравнение клинико-демографического портрета человека, перенёсшего инфаркт миокарда, по данным опроса репрезентативной выборки населения России в 2003 и 2023 гг.</p> <p><bold>Методы.</bold><bold> </bold>Ретроспективное исследование данных лонгитюдинального обследования домохозяйств «Российский мониторинг экономического положения и здоровья населения НИУ ВШЭ (RLMS-HSE)», представляющего серию ежегодных общенациональных репрезентативных опросов на базе вероятностной стратифицированной многоступенчатой территориальной выборки. На первом этапе исследования определена распространённость инфаркта миокарда среди всех опрошенных респондентов во временных точках 2003 г. и 2023 г. На втором этапе исследования проведено сравнение частоты артериальной гипертензии, сахарного диабета, острого нарушения мозгового кровообращения, курения и ожирения (индекс массы тела ≥30 кг/м<sup>2</sup>) в группах респондентов с положительным и отрицательным ответом о перенесённом инфаркте миокарда в 2003 и 2023 гг.</p> <p><bold>Результаты.</bold><bold> </bold>Возраст опрошенных в 2003 г. составил 45,0±17,8 года, в 2023 — 50,7±17,1 года, <italic>p &lt;</italic>0,001. Среди всех респондентов частота положительных ответов на вопрос «Ставили Вам когда-нибудь диагноз "инфаркт миокарда"?» в 2003 г. составила 2,7%, в 2023 г. — 2,2% (<italic>p &lt;</italic>0,01). Наблюдалась разница в частоте положительных ответов о наличии перенесённого инфаркта миокарда в выборках 2003 и 2023 гг. в трёх возрастных группах по полу. Различия между 2003 и 2023 гг. в возрасте до 45 лет были статистически значимые среди мужчин (<italic>p=</italic>0,01) и незначимые — среди женщин (<italic>p=</italic>0,5). В возрасте 45–60 лет различия были значимые как среди мужчин (<italic>p=</italic>0,001), так и среди женщин (<italic>p=</italic>0,014). Аналогично — в возрасте старше 60 лет: среди мужчин (<italic>p=</italic>0,009) и среди женщин (<italic>p=</italic>0,049). При отрицательном ответе респондента о наличии инфаркта миокарда в возрасте старше 60 лет отмечен даже небольшой прирост курящих (с 13,5% до 14,5%), а в возрасте 45–60 лет — тенденция к отказу от курения незначительная (с 34,6% до 32,8%).</p> <p><bold>Заключение.</bold><bold> </bold>Результаты свидетельствуют о снижении распространённости инфаркта миокарда среди мужчин и женщин при одновременном увеличении среднего возраста, частоты сахарного диабета и перенесённого инсульта среди респондентов, положительно ответивших на вопрос о перенесённом инфаркте миокарда.</p></trans-abstract><kwd-group xml:lang="en"><kwd>prevalence of myocardial infarction</kwd><kwd>clinical profile</kwd><kwd>patients</kwd><kwd>diabetes mellitus</kwd><kwd>smoking</kwd><kwd>survey</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>распространённость инфаркта миокарда</kwd><kwd>клинический портрет</kwd><kwd>пациенты</kwd><kwd>сахарный диабет</kwd><kwd>курение</kwd><kwd>опрос</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Deev IA, Kobyakova OS, Starodubov VI, et al.
