Клиническое подозрение на нестабильную стенокардию у пациентов с острой болью в груди низкого риска и ранее неверифицированной коронарной болезнью сердца (КБС) имеет ограниченную точность при принятии решения о необходимости инвазивной коронарной ангиографии. Подход к выбору оптимального неинвазивного диагностического теста, основанный на вероятности наличия у пациента обструктивного атеросклероза дает явные клинические преимущества, но точки принятия решения о неинвазивной ангиографии или функциональном тестировании для пациентов с острой болью в груди низкого и умеренного риска с ранее неверифицированной КБС не определены.</p></sec><sec><title>Цель</title><p>Цель. Мы провели небольшое поисковое исследование, чтобы найти точки принятия решения в пользу выбора стресс-эхокардиографии (стресс-ЭхоКГ) в качестве предпочтительного стартового теста у пациентов с острой болью в груди низкого и умеренного риска с ранее неверифицированной КБС.</p></sec><sec><title>Методы</title><p>Методы. В исследование включено 129 пациентов, возрастом 56 ± 11 лет, мужчин – 83 (64%), 97 (75%) пациентов имели ≥ 3 факторов риска ишемической болезни сердца (ИБС). Им проводилась стресс-ЭхоКГ с физической нагрузкой. С помощью инвазивной или неинвазивной коронарной ангиографии выявлялись истинно-положительные результаты стресс-ЭхоКГ. Высокая вероятность истинно-положительной стресс-ЭхоКГ была определена как аргумент в пользу выбора данной методики в качестве предпочтительного стартового теста. С помощью кластерного анализа все пациенты были разделены на группы на основании различий в сывороточных уровнях триглицеридов (ТГ), общего холестерина (ОХ), холестерина липопротеинов высокой плотности (ХС ЛПВП) и индекса атерогенности (ИА). Оценивались пороговые значения ТГ, ХС не-ЛПВП и ИА для определения принадлежности пациентов к группе, в которой вероятность истинно-положительной стресс-ЭхоКГ была высокой. Результаты. Частота истинно-положительной стресс-ЭхоКГ составила 8%. У пациентов с истинно-положительной стресс-ЭхоКГ были выше уровни ХС не-ЛПВП (p = 0,001) и ИА (p = 0,066) по сравнению с остальными пациентами. По результатам кластеризации среди всех пациентов были выделены 2 группы, объединившие 36% пациентов с наиболее высокими уровнями ХС не-ЛПНП и ИА. Отношение шансов для истинно-положительной стресс-ЭхоКГ в объединенной группе составило 7,2 (1,4–36,6). Уровень ХС не-ЛПНП &gt; 4,42 ммоль/л определял принадлежность к объединенной группе с чувствительностью 0,91, специфичностью 0,88 и площадью под ROC-кривой 0,97.</p></sec><sec><title>Выводы</title><p>Выводы. У пациентов с острой болью в груди низкого и умеренного риска с ранее неверифицированной КБС уровень ХС не-ЛПВП &gt; 4,42 ммоль/л может рассматриваться в качестве критерия для выполнения стресс-ЭхоКГ в качестве стартового теста.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Clinical suspicion of unstable angina in patients with previously unverified coronary artery disease (CAD) has limited efficacy in decisions whether invasive coronary angiography is necessary. A likelihood-based approach to selecting the optimal diagnostic test in evaluating chest pain offers distinct clinical benefits, but decision points for noninvasive angiography or functional testing for lowand intermediate-risk acute chest pain patients with previously unverified CAD remain undefined.</p></sec><sec><title>Aim</title><p>Aim: To find decision-making point to select stress-echocardiography (SE) as the initial test in lowto intermediate-risk acute chest pain patients with previously unverified CAD.</p></sec><sec><title>Methods</title><p>Methods. The study included 129 patients, aged 56 ± 11 years, of whom 83 (64%) were male and 97 (75%) had ≥ 3 risk factors for CAD. They underwent exercise SE. The diagnostic performance of SE was analyzed to identify true positive (TP) SE results; reference methods were invasive or noninvasive coronary angiography. TP SE was the target outcome in favor of SE as the initial test. All patients were clustered into phenogroups based on differences in serum triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and atherogenic index (AI). TC, non-HDL-C, and AI were used to determine thresholds for belonging to a phenogroup in which the odds of TP SE were higher.</p></sec><sec><title>Results</title><p>Results. The rate of TP SE was 8%. Patients with TP SE had higher levels of non-HDL-C (p = 0.001) and AI (p = 0.066) compared to the remaining patients. After clustering, 2 phenogroups were identified in the total study population, uniting the 36% of patients with the highest non-HDL-C and AI. The odds ratio for TP SE in this joint group was 7.2 (1.4–36.6). Non-LDL &gt;4.42 mmol/l estimate joint group membership with sensitivity 0.91, specificity 0.88, and area under curve 0.97.</p></sec><sec><title>Conclusion</title><p>Conclusion. Non-HDL-C &gt;4.42 mmol/l may be considered in low to intermediate risk acute chest pain patients with previously unverified CAD as a criterion for using SE as a starting test.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>боль в груди</kwd><kwd>острый коронарный синдром</kwd><kwd>стресс-эхокардиография</kwd><kwd>холестерин</kwd><kwd>коронарная болезнь сердца</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chest pain</kwd><kwd>acute coronary syndrome</kwd><kwd>stress echocardiography</kwd><kwd>high cholesterol levels</kwd><kwd>coronary artery disease</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">исследование выполнено без финансовой поддержки грантов, общественных, некоммерческих, коммерческих организаций и структур</funding-statement><funding-statement xml:lang="en">the study was carried out without financial support from grants, public, non-profit, commercial organizations and structures</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Durand E., Bauer F., Mansencal N., Azarine A., Diebold B., Hagege A. et al.
