Обследованы 277 человек с ХСН II-IV функциональных классов по классификации Нью-Йоркской ассоциации сердца  (NYHA).  Исследован  генетический  полиморфизм   С677Т гена МТГФР методом полимеразной цепной реакции. С целью выявления ассоциации гомоцистеина с характером течения ХСН больные были разделены  по итогам годичного наблюдения на 2 группы: с благоприятным (n=49)  и неблагоприятным  (n=45)  течением.  При этом в течение периода наблюдения оценивалось: нарастание симптомов и тяжести ХСН, частота госпитализаций  по поводу ХСН, динамика фракции выброса левого желудочка.</p></sec><sec><title>Результаты</title><p>Результаты. Носительство аллеля Т и генотипа Т/Т полиморфного локуса С677Т гена МТГФР ассоциировалась с повышенным риском развития  ХСН.  Также аллель  Т и  генотип  Т/Т  ассоциировались с более  тяжелой клинической картиной ХСН.  У больных ХСН  II-IV функциональным классом  концентрация  гомоцистеина  в плазме крови была существенно,  в 2-3 раза,  выше по сравнению с контролем независимо  от пола. В группе с неблагоприятным течением ХСН  уровень  гомоцистеина  оказался  наибольшим по сравнению с группой с благоприятным течением.</p></sec><sec><title>Заключение</title><p>Заключение.  Установлена  взаимосвязь  гипергомоцистеинемии с тяжестью и характером течения ХСН. Определение  уровня гомоцистеина в сыворотке крови и генетического полиморфизма С677Т гена МТГФР может быть рекомендовано для раннего прогнозирования тяжести и характера течения ХСН.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To study the influence of polymorphism of the gene methyltetrahydrofolate-reductase (MTHFR) — polymorhic locus С677Т, and level of homocysteine  in blood plasma on the risk of development and course of chronic heart failure (CHF).</p></sec><sec><title>Material and methods</title><p>Material and methods. Totally, 277 persons  studied  with CHF II-IV functional classes (FC NYHA). The polymorphism С677Т of gene MTHFR studied via polymerase chain reaction. With the aim to reveal association of homocysteine  with the course  of CHF patients were selected  by the results  of year-long observation  to 2 groups:  with benign (n=49) and adverse  (n=45) course.  During the period the following was assessed: increase  of  symptoms  and  severity  of  CHF, hospitalizations  rate, dynamics of the left ventricle ejection fraction.</p></sec><sec><title>Results</title><p>Results. Carriage  of allele T and  genotype  T/T of polymorphic locus С677Т gene MTHFR was associated with more severe clinical picture of CHF. In CHF patients of II-IV FC homocysteine concentration in serum was significantly, 2-3 times, higher comparing to the controls, regardless of age. In adverse course group the level was highest comparing to benign course.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>сердечная  недостаточность</kwd><kwd>гомоцистеин</kwd><kwd>метилентетрагидрофолатредуктаза</kwd><kwd>полиморфизм С677Т</kwd></kwd-group><kwd-group xml:lang="en"><kwd>heart failure</kwd><kwd>homocysteine</kwd><kwd>methyltetrahydrofolatereductase</kwd><kwd>polymorphism С677Т</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">Pogosova GV, Oganov RG, Koltunov IE, et al.
