The main group (n=70) included 30 patients with high normotension – subgroup A, and 40 patients with hypertension 1–2nd stage – subgroup B. The comparison group included 40 patients with "white coat hypertension".</p> <p><bold>Results. </bold>The most frequent complications in the 2nd and 3rd trimesters of pregnancy were toxaemia, threatened miscarriage, edema (detected in more than half of patients with high normotension and hypertension 1–2nd stage) and well as threatened preterm labor (<italic>p</italic>&lt;0.05). The frequency of pre-eclampsia development in subgroups A and B did not differ significantly, however, in patients with high normotension in the 3rd trimester during a test of endothelium-dependent vasodilation were detected signs of endothelial dysfunction, which may be one of the mechanisms for the subsequent formation of hypertension in these patients. Placental insufficiency of varying severity was detected only in subgroups A and B. Placental insufficiency, along with intrauterine fetal hypoxia of different etiologies, were the most frequent causes of emergency caesarean section, occurring only in the main group – 3 (75.0%) in subgroup A and 6 (66.67%) in subgroup B – and associated with blood pressure above 130/85 mm Hg.</p> <p><bold>Conclusion. </bold>The importance of preventing blood pressure increase to high normal rate is explained by the development of endothelial dysfunction at late gestation, which can serve as the mechanisms of hypertension formation in this category of pregnant women.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель. </bold>Произвести сравнительную оценку влияния высокого нормального давления (ВНД) и артериальной гипертензии (АГ) 1–2-й степени на риск развития гестационных и перинатальных осложнений.</p> <p><bold>Материалы и методы.</bold> Проведено проспективное когортное исследование (n=110) влияния ВНД на риск развития гестационных осложнений и исходы беременности. В основную группу (n=70) вошли 30 пациенток с ВНД, составив подгруппу А, и 40 пациенток с АГ 1–2-й степени, составив подгруппу Б. В группу сравнения включены 40 пациенток с «гипертензией белого халата».</p> <p><bold>Результаты. </bold>Во II и III триместрах беременности наиболее частыми осложнениями оказались токсикоз, угроза прерывания, отеки, выявляемые более чем у 1/2 пациенток с ВНД, и АГ 1–2-й степени, а также угроза преждевременных родов (<italic>р</italic>&lt;0,05). Частота развития преэклампсии в подгруппах А и Б значительно не отличалась, однако у пациенток с ВНД в III триместре при пробе эндотелийзависимой вазодилатации определялись признаки эндотелиальной дисфункции, что может быть одним из механизмов последующего формирования у этих пациенток АГ. Лишь в группах ВНД и АГ имела место плацентарная недостаточность различной степени выраженности. Плацентарная недостаточность наряду с внутриутробной гипоксией плода различной этиологии стали наиболее частными причинами выполнения экстренного кесарева сечения, встречавшегося лишь в основной группе, – 3 (75,0%) в подгруппе А и 6 (66,67%) в подгруппе Б – и ассоциировались с повышением артериального давления &gt;130/85 мм рт. ст.</p> <p><bold>Заключение. </bold>Важность профилактики повышения артериального давления до высоких нормальных цифр объясняется развитием на поздних сроках беременности эндотелиальной дисфункции, что может оказаться одним из механизмов формирования АГ у данной категории беременных.</p></trans-abstract><kwd-group xml:lang="en"><kwd>pregnancy</kwd><kwd>high normotension</kwd><kwd>hypertension</kwd><kwd>preeclampsia</kwd><kwd>cardiovascular risk</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>беременность</kwd><kwd>высокое нормальное давление</kwd><kwd>артериальная гипертензия</kwd><kwd>преэклампсия</kwd><kwd>сердечно-сосудистый риск</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Rao AK, Cheng YW, Caughey AB.
