[Distributions of polymorphisms of genes of some components of hemostasis in patients with ischemic heart disease].

We have studied structure of polymorphisms of genes of blood clotting factors II, V, VII, platelet membrane glycoprotein IIIa (GPIIIa) and enzyme methylenetetrahydrofolate reductase (MTHFR) in patients with ischemic heart disease (IHD). In this cohort of patients most prevalent are polymorphism PLAA1/A2 of GPIIIa gene and 677T/T polymorphism of MTHFR gene. Inconsistency of existing evidence on effect of R/Q genotype of FVII gene on early development of IHD and myocardial infarction (MI) is underlined, and data on the absence of protective effect of Q allele on early development of MI are presented. Activating effect of PLAA1/A2 polymorphism of GPIIIa gene and 677T/T polymorphism of MTHFR gene on morphofunctional state of platelets is proved.
