Aim. To evaluate the influence of genetic factors on the risk of developing a combined endpoint, during a one-year supervision of patients, who had myocardial infarction and highly adherent to drug therapy.Material and methods. The research included 250 patients with high adherence to treatment with myocardial infarction, using the method of polymerase chain reaction we determined the polymorphisms Thr174Met and Met235Thr in the AGT gene, Arg389Gly and Ser49Gly in the ADRB1 gene, Ser447Ter in the LPL gene and Leu28Pro in the APOE gene, Trp212Ter and G681A in the CYP2C19 gene, and then we evaluated their influence on the prognosis.Results. A significant influence on the risk of developing combined endpoint was noticed for the polymorphism of CYP2C19 (G681A) gene. For the GA genotype of the CYP2C19 gene (G6881A), the OR of developing an unsuccessful outcome was 1.97 (95 % CI 1.05 — 3.69) (P = 0.03). For сarrier-state of A allele the OR was 1.46 (95 % CI 1.06 — 3.64) (P = 0.03). Conclusion. The results received indicate the need for individual approach for the choice of drugs from the group of inhibitors P2Y12-receptors for dual antiplatelet therapy, and if clopidogrel is chosen it is necessary to resolve the issue of pharmacogenetic testing for CYP2C19.

Abstract Background Elderly patients form a large and growing part of the patients presenting with non-ST-elevation myocardial infarction (NSTEMI). Choosing the optimal antithrombotic treatment in these elderly patients is more complicated because they frequently have characteristics indicating both a high ischaemic and high bleeding risk. Purpose We describe the treatment of elderly patients (>75 years) admitted with NSTEMI, present the outcomes (major adverse cardiovascular events (MACE) and bleeding) and aim to find predictors for adverse events. Methods The POPular AGE registry is an investigator initiated, prospective, observational, multicentre study of patients aged 75 years or older presenting with NSTEMI. Patients were recruited between August 1st, 2016 and May 7th, 2018 at 21 sites in the Netherlands. The primary composite endpoint of MACE included cardiovascular death, non-fatal myocardial infarction and non-fatal stroke at one-year follow-up. Results A total of 757 patients were enrolled. During hospital stay 76% underwent coronary angiography, 34% percutaneous coronary intervention and 12% coronary artery bypass grafting (CABG). At discharge 78.6% received aspirin (non-users mostly because of the combination of oral anticoagulant and clopidogrel), 49.7% were treated with clopidogrel, 34.2% with ticagrelor and 29.6% were prescribed oral anticoagulation. Eighty-three percent of patients received dual antiplatelet therapy (DAPT) or dual therapy consisting of oral anticoagulation and at least one antiplatelet agent for a duration of 12 months. At one year, the primary outcome of cardiovascular death, myocardial infarction or stroke occurred in 12.3% of patients and major bleeding (BARC 3 or 5) occurred in 4.8% of the patients. The risk of MACE and major bleeding was highest during the first month and stayed high over time for MACE while the risk for major bleeding levelled off. Independent predictors for MACE were age, renal function, medical history of CABG, stroke and diabetes. The only independent predictor for major bleeding was haemoglobin level on admission. Conclusion In this all-comers registry, most elderly patients (≥75 years) with NSTEMI are treated with DAPT and undergoing coronary angiography the same way as younger NSTEMI patients from the SWEDEHEART registry. Aspirin use was lower as was the use of the more potent P2Y12 inhibitors compared to the SWEDEHEART which is very likely due to the concomitant use of oral anticoagulation in 30% of patients. The fact that ischemic risk stays constant over 1 year of follow-up, while the bleeding risk levels off after one month may suggest the need of dual antiplatelet therapy until at least one year after NSTEMI.

Abstract Objective To evaluate the contribution of gene polymorphism to the formation of renal dysfunction in patients with hypertension with high adherence to treatment. Methods and materials 88 working-aged subjects with non-complicated arterial hypertension (average age 48,65±7,24 yrs). All patients underwent evaluation of genotype for markers AGT Thr174Met, GNB3 C825T, MTHFR C677T, MTRR Ile22Met. To assess the glomerular function, cystatin C was measured in serum by ELISA, and serum level of NGAL was determined by ELISA to assess the function of the tubules.Depending on genotype peculiarities the following groups were formed: 1) 39 patients who had polymorphism of AGT Thr174Met in homozygous and 49 subjects without one; 2) 62 subjects who had polymorphism of GNB3 C825T in heterozygous and 26 subjects without one; 3) 52 subjects with polymorphism of MTHFR C677T in heterozygous and 36 subjects without one; 4) 48 subjects with polymorphism of MTRR Ile22Met in heterozygous and 40 subjects without one. Results Patients in the groups did not differ in sex, age, risk factors, comorbidities, concomitant medications, BP level, lipid spectrum. In the groups with the presence of the genes GNB3 and MTHFR polymorphism in the heterozygous form, the level of NGAL was significantly higher than in the groups with normal genotypes: 1.67±0.86 ng/ml versus 1.2±0.87 pg/ml (p=0.022), 1.49±0.61 pg/ml versus 1.21±0.56 ng/ml (p=0.034), respectively. At the same time, in these groups, the level of cystatin C was not significantly different. The AGT gene polymorphism groups differed significantly in cystatin C (p<0.001), but did not differ in the level of NGAL. In the group with the presence of the MTRR gene polymorphism, the level of cystatin C and the level of NGAL were significantly higher (p=0.042 and p=0.004, respectively). The correlation analysis revealed a moderate direct interconnections between cystatin C levels and the presence of the AGT gene polymorphism (r=0.46; p=0.017) and MTRR (r=0.33; p=0.039), as well as between the NGAL level and the presence of the GNB3 gene polymorphism (r=0.42; p=0.031), MTHFR (r=0.39; p=0.023) and MTRR (r=0.43; p=0.007). Conclusions In working-aged patients with uncomplicated hypertension with high adherence to treatment, the formation of renal dysfunction with a primary glomerular lesion is associated with the presence of polymorphism of the AGT gene in the heterozygous form. Formation of renal dysfunction with predominant tubular lesion is associated with the presence of GBN3 and MTHFR genes polymorphism of in the heterozygous form. And the formation of renal dysfunction with the damage of both glomeruli and tubules is associated with the presence of the MTRR gene polymorphism of the in the heterozygous form.

Abstract Myocardial infarction (MI), the leading cause of mortality and disability worldwide, is a disease in which multiple environmental and genetic factors are involved. Recently, researches suggested that insertion/deletion (ins/del) variation of NFKB1 gene rs28362491 is a functional polymorphism. In the present study, we aimed to explore the relation between variation of NFKB1 gene rs28362491 and MI by polymerase chain reaction–restriction fragment length polymorphism (PCR–RFLP) in 359 MI patients and 1085 control participants. Gensini score was used to evaluate the degree of coronary artery stenosis in MI patients. The plasma levels of interleukin-6 (IL-6), IL-8, malonaldehyde (MDA) and superoxide dismutase (SOD) were randomly measured by ELISA both in MI patients and control participants. We found that the detected frequencies of D allele (41.2% vs. 36.4%, P = 0.021) and DD genotype (17.5% vs. 12.0%, P = 0.022) were significantly higher in MI patients than in control participants. Compared with II or ID genotype carriers, the Gensini score in MI patients with DD genotype was 32–43% higher (both P < 0.001). Moreover, DD genotype carries had more diseased coronary arteries (P = 0.001 vs. II or ID genotype). Of note, IL-6 levels in MI patients carrying DD genotype were significantly higher than that in control participants and other genotype carriers in MI patients (both P < 0.05). In conclusion, NFKB1 gene rs28362491 DD genotype was associated with a higher risk of MI and more severe coronary artery lesion, which also had a potential influence on the level of inflammatory cytokine IL-6.
