Genotyping of a polymorphic marker 4G(-675)5G was performed by means of polymerase chain reaction followed by restriction fragment length analysis. Genomic deoxyribonucleic acid (DNA) was extracted from venous blood leukocytes. To determine the frequency distribution of genotypes and alleles of PAI-1 in ischemic heart disease all patients were divided into 6 groups depending on the course of the disease and its outcomes. </p> <p><bold>Results.</bold> In the population of Baku genotype 44 of PAI-1 gene is significantly more common in people with coronary artery disease compared to individuals without coronary artery disease and is a risk factor for this disease. Genotype 55 of PAI-1 gene is more common in people without coronary artery disease and thus is a protective genotype against this disease. Allele 4 of PAI-1 was statistically more frequently recorded in patients with ischemic heart disease, and allele 5 was significantly more frequently observed in patients without this pathology. Therefore, allele 4 is a risk factor for the occurrence of coronary heart disease and allele 5 is protective against this disease. Alleles 5 and 4 are not associated with the course and outcomes of ischemic heart disease. </p> <p><bold>Conclusion.</bold> According to the results of the study on the population of Baku, genotype 44 of PAI-1 gene is a risk factor of ischemic heart disease, genotype 55 of PAI-1 gene is protective against this pathology, allele 4 is characteristic for people with coronary artery disease (a risk factor), allele 5 is characteristic for people without it (protective role) whereas the named genotypes of PAI-1 are not connected to the course and outcomes of this disease.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель.</bold> Изучить связи различных генотипов и аллелей гена PAI-1 с характером течения ишемической болезни сердца. </p> <p><bold>Методы.</bold> Под наблюдением находились 80 пациентов с ишемической болезнью сердца (51 мужчина и 29 женщин) в возрасте от 39 до 65 лет, проживающих в г. Баку. Генотипирование полиморфного маркёра 4G(-675)5G проводили с помощью полимеразной цепной реакции с последующим анализом длин рестрикционных фрагментов. Геномную дезоксирибонуклеиновую кислоту выделяли из лейкоцитов венозной крови. Для определения частоты распределения генотипов и аллелей гена PAI-1 при ишемической болезни сердца все пациенты были разделены на шесть групп в зависимости от характера течения заболевания и его исходов. </p> <p><bold>Результаты.</bold> У жителей г. Баку генотип 44 гена PAI-1 статистически значимо чаще встречается при ишемической болезни сердца в сравнении с лицами без таковой и является фактором риска этого заболевания. Генотип 55 гена PAI-1 чаще встречается у людей без ишемической болезни сердца и, таким образом, является протективным генотипом в отношении развития данной болезни. Аллель 4 PAI-1 статистически чаще был зафиксирован у пациентов с ишемической болезнью сердца, а аллель 5 достоверно чаще выявлялся у людей без этой патологии. Следовательно, аллель 4 - фактор риска ишемической болезни сердца, а аллель 5 является протективным в этом отношении. Аллели 5 и 4 не ассоциированы с характером течения и исходом ишемической болезни сердца. </p> <p><bold>Вывод.</bold> По данным исследования жителей г. Баку, генотип 44 гена PAI-1 - фактор риска ишемической болезни сердца, генотип 55 гена PAI-1 - протективный в этом отношении генотип, аллель 4 характерен для людей с ишемической болезнью сердца (фактор риска), аллель 5 - для лиц без неё (протективная роль), причём указанные генотипы гена PAI-1 не связаны с характером течения и исходом данного заболевания.</p></trans-abstract><kwd-group xml:lang="en"><kwd>coronary artery disease</kwd><kwd>ischemic heart disease</kwd><kwd>myocardial infarction</kwd><kwd>outcomes</kwd><kwd>genotypes of PAI-1 gene</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>ишемическая болезнь сердца</kwd><kwd>инфаркт миокарда</kwd><kwd>исходы</kwd><kwd>генотипы гена PAI-1</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Баранов B.C., Хавинсон В.Х.
