ПАЦИЕНТЫ И МЕТОДЫ. Обследовано 340 больных с ХСН (200 - мужчин,  140 - женщин, средний возраст - 58±13 лет). Причиной ХСН у 44 (13%) больных была артериальная гипертензия, у 112 (33%) - ИБС, у 184 (54%) - их сочетание. Первый функциональный класс ХСН имели 112 (33%),  II -  177(52%),  III - 34 (10%),  IV -  17 (5%) больных.  Скорость клубочковой фильтрации  рассчитывали  по формуле MDRD. РЕЗУЛЬТАТЫ. Фракция выброса (ФВ) левого желудочка составила 56,9±10,5%. Систолическая дисфункция диагностирована у 90 (26%) больных. Митральная регургитация (МР) наблюдалась у 221  (65%) больного. СКФ составила 68,8±20,9 мл/мин/1,73м² (от 19,2 до 149,7 мл/мин/1,73м²). У 114 (34%) СКФ была ниже 60 мл/мин/1,73м². Наблюдалась прямая связь между Ф К ХСН и МР (г=0,35;р&lt;0,001). Изменения эхоструктуры клапанов, включая уплотнение створок, отмечены у 228 (67%) больных. СКФ обратно коррелировала с выраженностью МР (r=-0,43; p&lt;0,001). Многофакторный регрессионный анализ показал, что выраженность МР ассоциирована со снижением функционального состояния почек независимо от возраста пациентов.  ЗАКЛЮЧЕНИЕ. Изменения эхоструктуры митрального клапана у больных с хронической сердечной недостаточностью, обусловленной ИБС и (или) артериальной гипертензией, чаще наблюдаются у больных с СКФ менее 60 мл/мин/1,73м². Степень выраженности митральной регургитации прямо ассоциирована со снижением функционального состояния почек.</p></abstract><trans-abstract xml:lang="en"><p>THE AIM of the investigation was to determine the relations between mitral regurgitation (MR) and glomerular filtration rate (GFR) in patients with chronic heart failure (CHF). PATIENTS AND METHODS. Under examination there were 340 patients with CHF (200 men and 140 women, mean age - 58±13 years). Arterial hypertension was the cause of CHF in 44 (13%) patients, IHD - in 112 (33%), their combination - in 184 (54%) patients. The first class of CHF was found in 112 (33%) patients, the second class - in 177 (52%), the third class - in 34 (10%), the fourth - in 17 (5%) patients. GFR was calculated by the Md RD formula. RESULTS. Ejection fraction (EF) of the left ventricle was 56.9±10.5%. Systolic dysfunction was diagnosed in 90 (26%) patients.  Mitral regurgitation was observed in 221 (65%) patients. GFR was 68.8±20.9 ml/min/1.73 m² (from 19.2 to 149.7 ml/min/1.73 m²). In 114 (34%) patients GFR was lower than 60 ml/min/1.73 m². There was a direct relation between CHF FC and MR (r=0.35; p&lt;0.001). Changes to the valve echostructure, cusp induration included, were noted in 228 (67%) patients. GFR had an inverse correlation with the MR degree (r=0.43; p&lt;0.001). Multivariate regression analysis has shown that the degree of MR is associated with the declined functional state of the kidneys irrespective of the patients’ age. CONCLUSION. Changes to the mitral valve echostructure in patients with chronic heart failure due to IHD and/or arterial hypertension was more often observed in patients with GFR less than 60 ml/min/1.73 m². The degree of mitral regurgitation is directly associated with the decreased functional state of the kidneys.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>митральная регургитация</kwd><kwd>хроническая болезнь почек</kwd><kwd>хроническая сердечная недостаточность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mitral regurgitation</kwd><kwd>chronic kidney disease</kwd><kwd>chronic heart failure</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">Go AS, Yang J, Ackerson LM et al.
