Association of rs2230806 polymorphism with the development of acute cerebrovascular accident in patients with cardiovascular disease

Aim. To study the association of single nucleotide polymorphism (SNP) rs2230806 (C>T) with the development of acute cerebrovascular accident (CVA) in East Siberian patients with cardiovascular pathology and risk factors.

Material and methods. The study involved 260 patients with acute CVA (age [57,0; 51,0-62,0]) and 272 patients of control group (age [55,0; 51,0-62,0]). Among patients with acute CVA there were 157 men and 103 women. The control group included 170 men and 102 women. Examination of the experimental group included: acquisition of complaints, anamnesis, clinical examination, computed cerebral tomography, electrocardiography, echocardioscopy, ultrasound duplex scanning of extracranial brachiocephalic arteries, 24-hour monitoring of blood pressure and heart rate, analysis of the blood coagulation system. In patients of the experimental group, the following cardiovascular pathology and risk factors were present: arterial hypertension, paroxysmal supraventricular tachycardia, dyslipidemia, atherosclerosis of the brachiocephalic arteries, hemostatic system disorders. The control group was examined as part of the international HAPIEE project. Molecular genetic studies were performed by real-time PCR.

Results. In all analyzed groups and subgroups of patients, a statistically significant relationship was found between the CC genotype and the C SNP allele rs662799 (A>G) and an increased risk of stroke.

Conclusion. The CC genotype and the C SNP allele rs2230806 (C>T) increases the risk of acute cerebrovascular accident in patients regardless of previous cardiovascular pathology and risk factors, including in patients with arterial hypertension, supraventricular tachyarrhythmias, atherosclerosis of brachiocephalic arteries, and disorders of lipid metabolism and hemostatic system.
