Замена глутамина на аргинин в 389-м положении ведет к увеличению активности АМФ и повышению чувствительности β1-адренорецептора к стимуляции. При тиреотоксикозе плотность β1-адренорецептора в миокарде увеличивается, что делает данную когорту больных весьма показательной при изучении влияния полиморфизмов β1-адренорецептора. Целью настоящей работы явилось изучение влияния полиморфизма Glu389Arg на клинические и ЭхоКГ-показатели при тиреотоксикозе и их динамику в процессе лечения. Было обследовано 136 пациентов с болезнью Грейвса. В исследование не включались пациенты, имеющие сопутствующую патологию сердца и люди старше 55 лет. Среди обследованных пациентов у 18 человек был “дикий” тип (глутамин в 389-м положении – G/G – 1-я группа) и у 118 человек был гетерозиготный генотип (A/G – 2-я группа). Пациентов, гомозиготных по аргинину в 389-м положении, в обследованной популяции не было. Были выявлены достоверные различия по ОТС ЛЖ, ИМЛЖ, ВИР, Е/А. При этом число больных с ГЛЖ и диастолической дисфункцией (ДД) было значительно больше в 2-й группе (10 и 30% соответственно; р &lt;0,001). Через год на фоне стойкого эутиреоза, помимо описанных различий, были выявлены достоверные различия по рЛА, ДПЛЖ и абсолютной толщине стенок. Таким образом, при тиреотоксикозе данный полиморфизм может играть предикторную роль. Полученные результаты демонстрируют, что “дикий” тип (глицин в 389-м положении гена β1-адренорецептора) кардиопротективен и снижает риск развития ГЛЖ и ДД при тиреотоксикозе.</p></abstract><trans-abstract xml:lang="en"><p>Gly389Arg polymorphism β1-adrenoreceptors can influence the cardio-vascular prognosis. Human heart β1-adrenoreceptors perform a crucial role in mediating the cardiostimulant effects of norepinephrine. Understanding the significance of Gly389Arg polymorphism in the human heart is beginning to emerge, but not in adult patients with thyrotoxicosis. We've studied the Gly389Arg polymorphism of β1-adrenoreceptors gene in relation to Echo-cardiography parameters in 136 normotensive patients with a thyrotoxicosis without any CVD. Echo-CG was performed according to standard protocol before and during the thyreostatic treatment. The genotype distribution was as following: Gly/Gly – 25% (1 group (1 gr.)), Arg/Gly – 75% (2 group (2 gr.), Arg/Arg – 0%. There was significant difference between 1 and 2 gr. by relative left ventricle wall thickness, left ventricular mass index, isovolumic relaxation time, Е/А ratio. The frequency of diastolic dysfunction (DD) was in gr. 1–10%, in gr. 2–30%, р &lt;0.001. After treatment during a year this damages were saved. These data demonstrate, that Gly/Gly genotype of β1-adrenoreceptors gene can have cardioprotective effect leading to less of LV hypertrophy and diastolic dysfunction in patients with thyrotoxicosis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>полиморфизм β1 адренорецептора Glu389Arg</kwd><kwd>тиреотоксикоз</kwd><kwd>ЭхоКГ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Gly389Arg polymorphism β1 adrenoreceptors</kwd><kwd>thyrotoxicosis</kwd><kwd>Echo CG</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">Bahouth S.W.
