ПАЦИЕНТЫ И МЕТОДЫ. В исследование были включены 317 пациентов в додиализном периоде с ХБП 1-5 стадий, 46,1% мужчин и 53,9%  женщин, среднего возраста 50,7±15,2 лет с выполненной доплер-эхокардиографией. Пациенты с хроническим гломерулонефритом составляли 30,7%, с диабетической нефропатией 29,4%, с гипертонической болезнью 17,7%, с прочими заболеваниями - 22,0%.  РЕЗУЛЬТАТЫ ИССЛЕДОВАНИЯ. Кальциноз сердечных клапанов в обследованной группе выявлен у 22,1% пациентов: АК - у 6,3%, МК - 4,1% и обоих клапанов у 11,7%. При кальцинозе АК и МК чаще отмечался их стеноз (p&lt;0,001 и p=0,002 соответственно) и приклапанная регургитация 1-й и выше степени (p=0,002 и p=0,053). В группе пациентов с наличием кальциноза АК или МК были больше диаметр аорты (p=0,005), левого (p&lt;0,001) и правого предсердий (p&lt;0,001),  правого желудочка (p=0,007), толщина стенок правого (p&lt;0,001) и левого желудочков (p&lt;0,001), больше диаметр и давление в легочной артерии (p&lt;0,001), более выражена диастолическая дисфункция по показателю Е/А (p&lt;0,001), больше градиенты давления на МК (p&lt;0,001) и АК (p&lt;0,001) и потоки через МК (p&lt;0,001) и АК (p&lt;0,001). По данным многофакторного анализа с кальцинозом клапанов связаны следующие независимые факторы: диаметр предсердий (p&lt;0,001), максимальные градиенты давления на АК (p&lt;0,001), МК (p&lt;0,001), показатель E/A (p&lt;0,001), степень аортальной регургитации (p=0,004), диаметр ЛА (p=0,041). ЗАКЛЮЧЕНИЕ. Кальциноз МК и АК независимо от других факторов приводит к стенозу и недостаточности клапанов, повышению максимальных градиентов и максимальных потоков на АК, МК, дилатации предсердий, ЛА, диастолической дисфункции.</p></abstract><trans-abstract xml:lang="en"><p>THE AIM of the investigation was to determine the character of relationship between mitral valve (MV) calcification and aortal valve (AV) calcification and the state of myocardium in patients in the predialysis period of chronic kidney disease (CKD). PATIENTS AND METHODS. The investigation included 317 patients in the predialysis period with CKD of the I-V stages, 46.1% of men and 53.9% of women, mean age 50.7±15.2 years with Doppler-echocardiography performed. Patients with chronic glomerulonephritis made up 30.7%, with diabetic nephropathy - 29.4%, with essential hypertension -17.7%, with other diseases -22.0%. RESULTS. Cardiac valvular calcification was revealed in 22.1% of the examined patients: AV - in 6.3%, MV - 4.1% and of both valves in 11.7%. In calcification of AV and MV their stenosis was noted more often (p&lt;0.001 and p= 0.002 respectively) as well as perivalvular regurgitation of the1 degree and higher (p=0.002 and p=0.053). Patients with calcification of AV and  MV had greater diameter of the aorta (p=0.005), left (p&lt;0.001) and right atriums (p&lt;0.001), right ventricle (p=0.007), thickness of walls of the right (p&lt;0.001) and left (p&lt;0.001) ventricles, greater diameter and pressure in the pulmonary artery (p&lt;0.001), more pronounced diastolic dysfunction by the E/A index (p&lt;0.001), higher pressure gradients on MV (p&lt;0.001) and AV (p&lt;0.001) and flows through MV (p&lt;0.001) and AV (p&lt;0.001). By the data of multifactor analysis the following independent factors are associated with valvular calcification:  diameter of the atriums (p&lt;0.001), maximum gradient of pressure on AV (p&lt;0.001), MV (p&lt;0.001), the E/A index (p&lt;0.001), the aortal regurgitation degree (p=0.004), LA diameter (p=0.041). CONCLUSION. MV and AV calcification, irrespective of other factors, results in insufficiency of the valves, increased maximum gradients and maximum flows on AV and MV, dilatation of the atriums, LA, diastolic dysfunction.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кальциноз митрального и аортального клапанов</kwd><kwd>хроническая болезнь почек</kwd><kwd>додиализный период</kwd><kwd>доплер-эхокардиография</kwd><kwd>диастолическая дисфункция</kwd><kwd>дилатация предсердий</kwd><kwd>гипертрофия левого желудочка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>calcification of the mitral and aortal valves</kwd><kwd>chronic kidney disease</kwd><kwd>predialysis period</kwd><kwd>Doppler-echocardiography</kwd><kwd>diastolic dysfunction</kwd><kwd>atrium dilatation</kwd><kwd>hypertrophy of the left ventricle</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, Chertow GM, Fan D et al.
