Оценить выживаемость без необратимых сердечно-сосудистых событий (НС) и смерти у лиц с увеличенным пространственным углом QRS-T (spatial QRS-T angle, sQRS-Ta) на электрокардиограмме (ЭКГ) из региональной российской выборки в среднесрочной перспективе.</p></sec><sec><title>Материал и  методы</title><p>Материал и  методы. Проанализировано 1394 ЭКГ из случайной региональной выборки мужчин (30%) и женщин 25-64 лет, участников исследования ЭССЕ-РФ1. Женщины были в среднем на 5 лет старше мужчин, но в гендерных группах 45-64 лет различий в среднем возрасте не наблюдалось. Наблюдение за выборкой составило ~7 лет, выявлено 26 необратимых событий (НС: смерть от сердечно-сосудистых заболеваний, нефатальные инфаркт миокарда или инсульт) и 63 комбинированные конечные точки (ККТ) (НС или прогрессирование сердечной недостаточности, или реваскуляризация). НС и ККТ у мужчин отмечены чаще, чем у женщин: 3,7% vs 1,1% (p=0,003) и 6,9% vs 3,6% (p=0,01), соответственно. sQRS-Ta вычисляли как угол между интегральными векторами QRS и T в синтезированных ортогональных отведениях. Выживаемость оценивали по кривым Каплана-Мейера, используя логранговый критерий. p≤0,05 — для проверки статистических гипотез.</p></sec><sec><title>Результаты</title><p>Результаты. Гендерные группы не различались по среднему значению sQRSTa. Увеличенным считали sQRS-Ta ≥90o (Ув.sQRS-Ta). Расхождение кривых выживаемости к концу периода наблюдения у мужчин, имеющих Ув.sQRS-Ta на ЭКГ, относительно мужчин с sQRS-Ta &lt;90o было больше, чем у женщин: 0,88 vs 0,96 для ККТ (p=0,0026) и 0,93 vs 0,96 для НС (p=0,009); у женщин — 0,94 vs 0,98 только для ККТ (p=0,0016). Первые НС и ККТ у мужчин с Ув.sQRS-Ta возникали раньше, чем с нормальным sQRS-Ta и чем у женщин с Ув.sQRSTa. Различий в частоте Ув.sQRS-Ta среди 45-64-летних мужчин и женщин не отмечено, но НС у мужчин с Ув.sQRS-Ta встречались в 5 раз чаще, чем у женщин. По данным двухфазной логистической регрессии, шанс возникновения НС у мужчин в 4,35 раз выше, чем у женщин (p=0,0002), а после внесения поправки на пол, у лиц с Ув.sQRS-Ta в 2,75 раз выше, чем у лиц с sQRS-Ta &lt;90o (p=0,015).</p></sec><sec><title>Заключение</title><p>Заключение. У мужчин с Ув.sQRS-Ta (≥90o) выживаемость без наступления НС или ККТ была хуже, а продолжительность жизни короче, чем у мужчин с нормальным sQRS-Ta или у женщин с Ув.sQRS-Ta. На прогноз НС статистически значимое влияние оказали мужской пол и Ув.sQRS-Ta на ЭКГ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To evaluate medium-term survival without irreversible and fatal cardiovascular events in individuals with a high spatial QRS-T angle (sQRS-Ta) from a regional Russian sample.</p></sec><sec><title>Material and methods</title><p>Material and methods. We analyzed 1394 electrocardiographic records from a random regional sample of men (30%) and women aged 25-64, which were included in the ESSE-RF1 study. Women were on average 5 years older than men, but there was no difference in mean age in the 45-64 groups. The follow-up period lasted 7 year; 26 irreversible events (cardiovascular death, non-fatal myocardial infarction or stroke) and 63 composite endpoints (CEs) (irreversible event or heart failure progression or revascularization) were identified. Irreversible events and composite endpoint in men were noted more often than in women as follows: 3,7% vs 1,1% (p=0,003) and 6,9% vs 3,6% (p=0,01), respectively. sQRS-Ta was estimated as the angle between the integral QRS and T vectors in the orthogonal leads. Survival was assessed by Kaplan-Meier curves using a log-rank test. Differences were considered significant at p≤0,05.</p></sec><sec><title> Results</title><p> Results. Sex groups did not differ in mean sQRS-Ta. sQRS-Ta ≥90o was considered to be increased. The divergence of survival curves by the end of follow-up period in men with increased sQRS-Ta relative to men with sQRS-Ta &lt;900 was greater than in women as follows: 0,88 vs 0,96 for CE (p=0,0026) and 0,93 vs 0,96 for irreversible events (p=0,009); in women — 0,94 vs 0,98 for CE only (p=0,0016). Initial event and CE in men with increased sQRS-Ta occurred earlier than those with normal sQRS-Ta and then in women with increased sQRS-Ta. There were no differences in the frequency of sQRS-Ta increase among 45-64-year-old men and women, but irreversible events in men with increased sQRS-Ta occurred 5 times more often than in women. According to two-stage logistic regression, the probability of irreversible event in men is 4,35 times higher than in women (p=0,0002). After adjusting for sex, in individuals with increased sQRS-Ta, it is 2,75 times higher than in individuals with sQRS-Ta &lt;90o (p=0,015).</p></sec><sec><title>Conclusion</title><p>Conclusion. In men with increased sQRS-Ta (≥90o), survival without irreversible and fatal cardiovascular events was worse, and life expectancy was shorter than in men with normal sQRS-Ta or women with increased sQRS-Ta. The prognosis of irreversible events was significantly affected by male sex and sQRS-Ta increase.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>прогноз</kwd><kwd>увеличенный пространственный угол QRS-T</kwd><kwd>конечные точки</kwd><kwd>необратимые сердечно-сосудистые события</kwd></kwd-group><kwd-group xml:lang="en"><kwd>prognosis</kwd><kwd>increased spatial QRS-T angle</kwd><kwd>endpoints</kwd><kwd>irreversible cardiovascular events</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Arteyeva NV.
