Несмотря на значительный прогресс в области коронарных вмешательств хронические окклюзии коронарных артерий (ХОКА) представляют значимую проблему для интервенционных кардиологов.</p></sec><sec><title>Цель</title><p>Цель. Разработать шкалу, которая позволит определить исходную стратегию реканализации ХОКА.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Были проанализированы клинические и ангиографические характеристики 665 пациентов, у которых выполнялась 681 попытка реканализации в ФГБУ «НМИЦ им. ак. Е.Н. Мешалкина» с 2014-го по 2017 год. 477 чрескожных коронарных вмешательств (ЧКВ) ХОКА составили группу создания шкалы, 204 ЧКВ ХОКА – группу проверки. Прогностическая модель была разработана путем присвоения баллов для каждого независимого предиктора процедурного неуспеха в соответствии с бета-коэффициентами и суммирования всех полученных баллов.</p></sec><sec><title>Результаты</title><p>Результаты. Процедурный успех был достигнут в 76,7% случаев. При многофакторном анализе были получены следующие предикторы процедурного неуспеха: извитость в теле окклюзии (1 балл), кальциноз (1 балл), неопределенная культя (1 балл), поражение артерии донора (1 балл), локализация окклюзии в бассейне огибающей артерии (ОА) или передней нисходящей артерии (ПНА) (0,5 балла). На основании данных предикторов были выделены 4 категории сложности окклюзий: &lt; 1 балла (легкие), ≥ 1 и &lt; 2 баллов (умеренно трудные), ≥ 2 и &lt; 3 баллов (трудные), ≥ 3 баллов (очень трудные). Полученная шкала продемонстрировала умеренную дискриминационную способность (площадь под ROC-кривой была 0,709 (95% ДИ 0,658–0,760). Согласно шкале «CHOICE» ретроградная реканализация должна рассматриваться в качестве первичной стратегии у пациентов с баллами 3 и более (очень трудные окклюзии).</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Despite signifcant progress in the feld of coronary interventions, chronic total occlusion (CTO) represents a signifcant challenge for interventional cardiologists.</p></sec><sec><title>Aim</title><p>Aim. To develop the score, able to predict technical success of CTO PCI and facilitate the choice of recanalization strategy.</p></sec><sec><title>Methods</title><p>Methods. A total of 665 CTO patients who underwent 681 PCI in the period from 2014 to 2018 in Meshalkin National Medical Research Center were included in this study. Clinical and angiographic characteristics were analyzed. 477 CTO PCI were randomly assigned to the derivation set, 204 CTO PCI – validation set. The prognostic model was developed by assigning a score for each independent predictor of procedural failure in accordance with beta coeffcients and summing up all scores.</p></sec><sec><title>Results</title><p>Results. Procedural success was 76.7%. Five predictors of procedural success were included into the fnal multivariable model: bending (1 score), calcifcation (1 score), ambiguous stump (1 score), “donor” artery disease (1 score), non-RCA CTO (0.5 scores). Based on these predictors, 4 categories of CTO complexity were highlighted: 0–1 scores (easy), 1–2 scores (intermediate), 2–3 scores (diffcult), &gt; 3 scores (very diffcult). The score demonstrated a good discriminatory ability (AUC 0.709, 95% CI 0.658–0.760). According to the novel score retrograde approach may have an advantage in patients with a &gt; 3 scores, which corresponds to the "very diffcult" class of complexity.</p></sec><sec><title>Conclusion</title><p>Conclusion. The novel score can be used in clinical practice for predicting the success of CTO PCI and determining initial crossing strategy.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ХОКА</kwd><kwd>Шкала</kwd><kwd>ЧКВ</kwd><kwd>Реканализация</kwd><kwd>Технический успех</kwd><kwd>Гибридный подход</kwd></kwd-group><kwd-group xml:lang="en"><kwd>CTO</kwd><kwd>Score</kwd><kwd>PCI</kwd><kwd>Recanalization</kwd><kwd>Technical success</kwd><kwd>Hybrid approach</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">Morino Y., Abe M., Morimoto T., Kimura T., Hayashi Y., Muramatsu T., Ochiai M. et al.
