“…Частота развития больших и клинически значимых кровотечений оказалась даже более высокой, чем частота развития ССО -26,1 %. За время наблюдения на фоне МАТ (в 86 % случаев состоящей из 3 компонентов) наиболее часто регистрировались большие и клинически значимые желудочно-кишечные кровотечения (из верхних и нижних отделов желудочно-кишечного тракта), что согласуется с данными крупных регистров и наших предыдущих исследований [2, [17][18][19].…”

Aim Searching for clinical, angiographic, and biochemical predictors of cardiovascular complications (CVC) and hemorrhagic complications in patients with atrial fibrillation (AF) receiving a multicomponent antithrombotic therapy (MAT) for an elective percutaneous coronary intervention (PCI). Patients with ischemic heart disease (IHD) and AF who require MAT for PCI are at a high risk of thrombotic complications (stroke, systemic embolism, coronary events) and hemorrhage. This warrants searching for new risk factors determining prediction of the outcome.Materials and methods This study included 207 patients (146 males aged 70.1±8.3 years) with IHD and AF who received direct oral anticoagulants (DOAC) as a part of their MAT therapy. Median duration of the follow-up was 12 [8.0; 12.0] months. The efficacy endpoint was a sum of CVCs combining cardiovascular death, ischemic stroke, venous thromboembolic complications, acute coronary syndrome (ACS), and requirement for an unscheduled PCI. “Coronary events”, including ACS and requirement for an unscheduled PCI were analyzed separately. The safety endpoint was BARC type 2-5 bleeding. Upon admission, biomarkers (growth-differentiation factor 15 (GDF-15), D-dimer, thrombin-activated fibrinolysis inhibitor (TAFI), and plasminogen activator inhibitor-1 (PAI-1)) were measured for all patients. Searching for prognostically significant indexes was performed with the Cox proportional hazards regression.Results Incidence of all CVCs was 16.4 %. Independent predictors of CVC included the DOAC treatment at a reduced dose (odds ratio (OR) 2.5 at 95 % confidence interval (CI) 1.02-6.15; p=0.0454), GDF-15 >1191 pg /ml (OR 3.76 at 95 % CI, 1.26-11.18; p=0.0172), PAI-1 >13.2 U/ml (OR 2.67 at 95 % CI, 1.13-6,26; p=0.0245). Incidence of coronary complications was 9.2 %. Independent predictors of coronary complications included a SYNTAX index >26.5 (OR 4.5 at 95 % CI, 1.45-13.60; p=0.0090), PCI for chronic coronary occlusion (OR 3.21 at 95 % CI, 1.10-9.33; p=0.0326), a GDF-15 >1191 pg/ml (ОR 4.70 at 95 % CI, 1.32-16.81; p=0.0172). Incidence of BARC type 2-5 bleeding was 26.1 %. The only independent predictor for hemorrhage complications was the total PRECISE-DAPT score >30 (ОR 3.22; 95 % CI, 1.89-5.51; р<0.0001).Conclusion Three independent predictors of CVC were identified for patients with IHD and AF treated with MAT following an elective PCI: treatment with a reduced dose of DOAC, GDF-15 >1191 pg /ml, and PAI-1>13.2 U/ml. Independent predictors of coronary complications included a SYNTAX index >26.5, PCI for chronic coronary occlusion, and GDF-15 >1191 pg/ml. The factor associated with a risk of bleeding was the total PRECISE-DAPT score >30.

Aim. Patients with atrial fibrillation (AF) at high risk of thromboembolic complications who have had bleeding should strive to resume anticoagulant therapy. Existing traditional scales for assessing the risk of hemorrhagic complications are not highly specific for the risk of recurrent bleeding. Thus, searching is needed for clinical and laboratory predictors to identify patients who require a personalized monitoring regimen. The aim of the study was to assess the incidence rate and predictors of recurrent major and clinically significant bleeding in patients with AF after resumption of the anticoagulant therapy, as well as the contribution of changing the anticoagulant to the treatment safety.Material and methods. Based on a 5-year follow-up of 95 patients with AF who have had major and clinically significant bleeding, the incidence and clinical factors determining the recurrence of hemorrhagic complications were assessed.Results According to the data of the 5-year follow-up, the recurrence rate of major/clinically significant bleeding was 16.9/100 patient-years. Changing the oral anticoagulant significantly reduced the risk of relapse after clinically significant bleeding and did not affect the risk of recurrence of major bleeding. The predictor for relapse of major/clinically significant bleeding during the therapy resumption was chronic kidney disease with a decrease in creatinine clearance to less than 60 ml/ min, which increased the risk of relapse 2.27 times (95% confidence interval: 1.1253-4.6163; p=0.0221).Conclusion. The development of serious bleeding in a patient at high risk of thrombotic complications always requires a reassessment of risk factors and an adequate choice and dosage of the anticoagulant. Development of a unified protocol for the management of AF patients receiving anticoagulants and having a high risk of bleeding is essential and will reduce the risk of adverse outcomes.

After the appearance of direct oral anticoagulants (DOAC), the use of vitamin K antagonists (VKA) has become more rare, but nevertheless, there are diseases in which they remain indispensable drugs. This review is devoted to VKA and the diseases in which these drugs can be used. The article compares the mechanism of action of VKA and DOAC, discusses methods of monitoring VKA therapy. Among the diseases of non-alternative use of VKA, mechanical prosthetic heart valves, atrial fibrillation in patients with moderate and severe mitral stenosis, antiphospholipid syndrome should be mentioned. Another indication for the appointment of anticoagulants is thrombosis of the left ventricle. In patients who have survived a myocardial infarction complicated by left ventricular thrombosis, anticoagulant treatment should be continued for up to 6 months with repeated imaging control. For this purpose, warfarin is successfully used. Currently, there is insufficient data to recommend the routine use of DOAC in patients with KrCl less than 25–30 ml/min, and in routine practice, warfarin remains the main anticoagulant in such patients. Direct oral anticoagulants have practically not been studied in the so-called special groups of patients: patients with congenital thrombophilia and rare localizations of thrombosis. There were practically no such patients in randomized trials and very little is known about the effectiveness of DOAC, so today warfarin remains the main drug for their treatment. Despite the fact that DOAC has displaced VKA in patients with non-valvular AF, we should not forget that it is VKA that we are obliged to prove the effectiveness of anticoagulants in patients with AF. The article discusses the pharmacogenetics of warfarin in relation to the data of the Russian Federation, as well as the practically important question of the possibility of resuming anticoagulants in patients with bleeding, the results of their own research are presented.
