The impact of cholesterol and different classes of lipoproteins on the development of coronary artery disease (CAD) has been investigated in extensively during the past 50 years. The cholesterol metabolism is dependent on numerous factors, including dietary fat, fractional absorption of dietary cholesterol, tissue stores of cholesterol, endogenous cholesterol synthesis, and fecal bile excretion. Several studies showed significantly lower amounts of bile acid secretion in adult patients with CAD compared to non-CAD patients. Could it be that the inability to efficiently excrete bile acids may lead to CAD development?

In the last decades, the effective management of some cardiovascular risk factors in the general population has led to a progressive decrease in the prevalence of coronary artery disease (CAD). Nevertheless, coronary heart disease remains the major cause of death in developed and developing countries and chronic coronary syndromes (CCS) are still a major target of utilization of non-invasive cardiac imaging and invasive procedures. Current guidelines recommend the use of non-invasive imaging in patients with CCS to identify subjects at higher risk to be referred for invasive coronary angiography and possible revascularization. These recommendations are challenged by two opposite lines of evidence. Recent trials have somewhat questioned the efficacy of coronary revascularization as compared with optimal medical therapy in CCS. As a consequence the role of imaging in these patients and in in patients with ischemic cardiomyopathy is under debate. On the other hand, real-life data indicate that a consistent proportion of patients undergo invasive procedure and are revascularized without any previous non-invasive imaging characterization. On top of this, the impact of COVID-19 pandemic on the sanitary systems caused a change in the current management of patients with CAD. In the present review we will discuss these conflicting data analyzing the evidence which has been recently accumulated as well as the gaps of knowledge which should still be filled.

Гены тромбообразования и фолатного обмена играют важную роль в развитии и прогрессии ишемической болезни сердца (ИБС). Однако о возможной роли полиморфных маркеров в рецидиве ИБС после чрескожного коронарного вмешательства (ЧКВ) известно недостаточно. Цель исследования: Оценить роль генетических факторов системы тромбообразования и фолатного обмена (полиморфных маркеров генов F5, F2, F13A1, PAI1, HPA1, MTHFR, FGB ), в возобновление клиники ИБС после ЧКВ. Методика: Исследование проводили с использованием выборки из 90 больных ИБС в возрасте от 40 до 75 лет: 75 пациентов после планового ЧКВ (60 мужчин и 15 женщин) и 15 лиц после экстренного ЧКВ (12 мужчин и 3 женщины). Молекулярно-генетическое исследование было выполнено с помощью комплекта реагентов «Сердечно-сосудистые заболевания СтрипМетод»® (ViennaLab Diagnostics GmbH, Австрия), выявляющие следующие варианты: F5, F2, F13A1, PAI1, HPA1, MTHFR, FGB . Результаты: В результате исследования была показана ассоциация полиморфного маркера G103T ( Val34Leu ) гена F13A1 (фактор свертываемости крови 13, субъединица A1) с развитием рецидивирующего состояния ИБС после ЧКВ. Выявлены статистически значимые различия в распределении частот генотипов полиморфного маркера Val34Leu гена F13A1 . Показано, что частота генотипа Val/Val у пациентов с осложнениями была выше, чем у пациентов без таковых: 0,700 и 0,400 соответственно (c = 7,78; p = 0,020), при этом генотип Val/Val проявил себя как фактор риска развития осложнений: ОШ = 3,50 (95%ДИ 1,37-8,93). При сравнении аллелей выявили, что частота аллеля L у больных с осложнениями была ниже, чем у лиц без таковых: 0,167 и 0,375 соответственно (p = 0,004), и носительство аллеля L уменьшало вероятность развития осложнений: ОШ = 0,33 (95%ДИ 0,15-0,72). Заключение: Носительство варианта 34V гена F13A1 , кодирующего A-субъединицу фактора свёртывания 13, предрасполагает к возобновлению клинических проявлений ИБС после ЧКВ. Genes of thrombosis and folate metabolism play an important role in development and progression of coronary artery disease (CAD). However, a possible role of polymorphic markers in CAD relapse following percutaneous coronary intervention (PCI) is not sufficiently understood. Background. Reports have indicated an association of genetic factors generally related with thrombophilia and recurrence of symptoms for coronary artery disease (CAD) following a percutaneous coronary intervention (PCI) due to restenosis and in-stent thrombosis. However, the relapse can also be caused by progression of atherosclerosis and endothelial dysfunction in unoperated blood vessels. Aim: To assess the role of genetic risk factors involved in thrombosis and folate metabolism (polymorphic markers of F5, F2, F13A1, PAI1, HPA1, MTHFR, and FGB genes) in recurrence of CAD symptoms after PCI. Methods: The study included 90 patients with CAD aged 40-75; 75 of these patients had undergone elective PCI (60 men and 15 women) and 15 patients - emergency PCI (12 men and 3 women). Molecular genetic tests were performed using a CVD StripAssays® reagent kit (ViennaLab Diagnostics GmbH, Austria) to identify the following genetic variations: F5, F2, F13A1, PAI1, HPA1, MTHFR, and FGB . Results: The study results showed a significant association of the G103T ( Val34Leu ) polymorphism in the F13A1 gene with relapses of IHD after PCI. Significant differences were found in genotype distribution frequencies of the Val34Leu polymorphism in the F13A1 gene. The frequency of Val / Val genotype was higher in patients with complications than without complications, 0.700 and 0.400, respectively (c = 7.78, p = 0.020). Furthermore, the Val/Val genotype can be classified as a risk factor for complications (OR = 3.50; 95% CI, 1.37-8.93). The L allele frequency was lower in patients with complications than in those without complications (0.167 and 0.375, respectively, p = 0.004), and carriage of the L allele reduced the likelihood of complications (OR = 0.33; 95% CI 0.15-0.72). Conclusion: Carriage of the 34V variant in the F13A1 gene that encodes the coagulation factor XIII A subunit predisposes to a relapse of CAD symptoms after PCI.
