Abstract
Currently, the issues of recurrent course of cardiovascular diseases are given great importance. Today, there is a search for more and more new factors and causes, including genetic ones, that contribute to the increase in the incidence of circulatory system diseases. The study of polymorphic variants of hemostasis system genes made it possible to study the molecular mechanisms underlying the causes of cardiovascular complications. Polymorphism of theSERPINE-1gene, encoding plasminogen activator inhibitor-1, is associated with the occurrence of cardiovascular diseases. This literature review examines the influence ofSERPINE-1gene polymorphism and the concentration of the plasminogen activator inhibitor-1 it encodes on the development and severity of circulatory system diseases; as well as the role of plasminogen activator inhibitor-1 as one of the indicators reflecting the antifibrinolytic potential of the blood. Taking into account the opinion of most authors, we can conclude that the polymorphism of theSERPINE-1gene and its homozygous variant 4G/4G, due to which the synthesis of plasminogen activator inhibitor-1 is increased, is an unfavorable predictor of many pathological processes. However, most of the data have been obtained on the association of theSERPINE-1gene polymorphism with cardiovascular diseases, where, according to most authors, the 4G/4G genotype is a prognostically negative variant. However, a number of researchers believe that the heterozygous 5G/4G variant is likely associated with the occurrence of cerebral ischemia. The inconsistency of the data obtained, ofcourse, requires further study of the characteristics of theSERPINE-1gene polymorphism in various pathological conditions, which is an important prerequisite for understanding the mechanisms of a number of diseases. To prepare the review, a literature search method in PubMed databases for the period 2013–2023 was used.
