The process of atherothrombosis lies in the genesis of MI development. An important mechanism of thrombus development is the genetic determinancy of methylenetetrahydrofolate reductase (MTHFR) gene. The purpose of this work was to study of this gene genotypes carriage and to estimate its prognostic significance in the development of myocardial infarction in the indigenous population of the Republic of Mordovia, depending on nationality. 88 patients with Q MI (Russian patients n = 48, Mordvia-Moksha n = 40) and 100 healthy subjects (Russians n = 50 and Mordva-Moksha n = 50) have been examined. The average age of patients with Q MI was (58,8 ± 6,4) years. In patients with Q MI, the carriage of the TT genotype of the MTHFR gene has been detected in 41 % of cases, and in healthy individuals of this genotype it has not been revealed. In patients of Mordvian nationality (moksha), the carriage of the genotype TT of the MTHFR gene was more frequent (47,5 %) than in patient of Russian nationality (37,5 %), with OR for the Mordovian-Moksha patients equal to 11.40 (CI 1.38-94, 0) and for patients of Russian nationality with OR = 7,69 (CI 1.57-37.76). It reflects a more significant risk of carriage of the TT genotype in patients of Mordvian (moksha) nationality in terms of increased thrombus formation and MI development.</p></abstract><trans-abstract xml:lang="ru"><p>Инфаркт миокарда (ИМ) занимает одно из ведущих положений среди осложнений сердечно-сосудистой системы. В генезе развития ИМ лежит процесс атеротромбоза. Важным механизмом развития тромба является генетическая детерминированность по гену метилентетрагидрофолатредуктазы (MTHFR). Целью работы явилось изучение носительства генотипов данного гена и оценка его прогностической значимости в развитии ИМ у населения Республики Мордовия в зависимости от национальной принадлежности. Было обследовано 88 пациентов с Q ИМ (русские пациенты n = 48, мордва-мокша n = 40) и 100 здоровых лиц (русские n = 50 и мордва-мокша n = 50). Средний возраст пациентов с Q ИМ составил (58,8 ± 6,4) лет. У пациентов с Q ИМ в 41 % случаев выявлено носительство генотипа ТТ гена MTHFR, а у здоровых лиц данного генотипа выявлено не было. У больных мордва-мокша, носительство генотипа ТТ гена MTHFR встречалась чаще (47,5 %), чем у больных русской национальности (37,5 %), с OR для больных мордва-мокша равному 11,40 (ДИ 1,38-94,0), а для больных русской национальности с OR= 7,69 (ДИ 1,57-37,76), что отражает более значимый риск носительства генотипа ТТ для больных мордва-мокша в плане повышенного тромбообразования и развития ИМ.</p></trans-abstract><kwd-group xml:lang="en"><kwd>gene of methylenetetrahydrofolate reductase</kwd><kwd>myocardial infarction</kwd><kwd>nationality</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>ген метилентетрагидрофолатредуктазы</kwd><kwd>инфаркт миокарда</kwd><kwd>национальность</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Доклад ВОЗ.
