Наряду с традиционными клинико-инструментальными исследованиями, проводилась идентификация полиморфных генотипов методом полимеразной цепной реакции (ПЦР). При анализе носительства полиморфных генотипов гена MTHFR выявлено достоверное преобладание промежуточных генотипов (в позиции 677 генотип СТ  – 88%, в позиции 1298 генотип АС – 66%) независимо от национальной принадлежности больных АГ. Носительство «неблагоприятных» генотипов ТТ гена MTHFR позиции 677 преобладает у мужчин мордва-мокша (20%) по сравнению с больными русской национальности. В течение 3-летнего наблюдения 12% больных с АГ (6,9% мордва-мокша и 5,1%  – русской национальности) перенесли острый инфаркт миокарда (ИМ) или острое нарушение мозгового кровообращения (ОНМК). Кардиоваскулярные осложнения (ИМ/ОНМК) встречались в 1,5 раза чаще у больных мордовской национальности, чем у больных с АГ русской национальности. ИМ встречался в 3 раза чаще у мужчин мордва-мокша, чем у больных с АГ русской национальности. Носители «неблагоприятных» генотипов ТТ гена MTHFR в позиции 677 мужчины мордва-мокша с АГ в 100% получили осложнение в виде ИМ.</p></abstract><trans-abstract xml:lang="en"><p>The article provides data on 114 patients with stage 2 primary arterial hypertension (AH) according to the WHO classification (2008) and the development of complications associated with hemostasis violations depending on the nationality of patients (Mordva-Moksha, Russians) and polymorphism methyltetrahydrofolate reductase (MTHFR) gene carrier state. Polymorphic genotypes were identified using polymerase chain reaction (PCR) along with traditional clinical and instrumental studies. The analysis of MTHFR gene polymorphic genotypes carriage showed a significant predominance of intermediate genotypes (88% – CT genotype at position 677, 66% – AC genotype at position 1298) regardless of nationality of patients with AH. The carriage of “unfavourable” TT genotypes of MTHFR gene at position 677 prevails in men of the Mordva-Moksha (20%) as compared with the patients of Russian nationality. During a 3-year follow-up, 12% of patients with AH (6.9% of MordvaMoksha and 5.1% of Russian) suffered acute myocardial infarction (MI) or acute cerebrovascular accident (ACVA). Cardiovascular complications (MI/ACVA) developed 1.5 times more often in Mordva patients than in patients with AH of Russian nationality. IM occurred 3 times more often in Mordva-Moksha men than in patients with AH of Russian nationality. The Mordva-Moksha men with AH, who were carriers of the “unfavourable” TT genotypes of MTHFR gene at position 677, developed a complication in the form of MI in 100% cases.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>артериальная гипертония</kwd><kwd>ген метилентетрагидрофолатредуктазы</kwd><kwd>кардиоваскулярные осложнения</kwd><kwd>национальность</kwd><kwd>пол</kwd></kwd-group><kwd-group xml:lang="en"><kwd>arterial hypertension</kwd><kwd>methylenetetrahydrofolate reductase gene</kwd><kwd>cardiovascular complications</kwd><kwd>nationality</kwd><kwd>sex</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">Здравоохранение в России. 2017: Стат. сб.
