Introduction.Upper gastrointestinal (UGI) bleeding is a common complication of antiplatelet therapy. Data from real clinical practice that characterize the range of risk factors for UGI bleeding, prophylactic proton pump inhibitors (PPIs) therapy, bleeding frequency and their long-term effects in patients with stable coronary artery disease (CAD) are limited. Aim.To identify predictors of UGI bleeding in patients with stable CAD, to assess the role of PPI in the prevention of bleeding and the long-term prognosis of patients after bleeding. Materials and methods.934 patients with stable CAD (median age 61 [5368] years, 78.6% men) were included in the single institution prospective REGistry of Long-term AnTithrombotic TherApy (REGATTA). Atherosclerosis of peripheral arteries (APA) and abdominal aortic aneurysm (AAA) screening was performed by doctor decision, as well as esophagogastroduodenoscopy. 76% of patients received dual antiplatelet therapy for 612 months after elective PCI. PPIs were prescribed in 28.3% of cases. Results.The median follow-up was 2.5 [1.15.1] years. The frequency of overt UGI bleeding was 1.9 per 100 patients per year. Anamnesis of peptic ulcer disease (OR 4.7; 95% CI 1.911.8;p=0.001), erosion of the upper gastrointestinal tract (OR 6.7; 2.716.6;p=0.00004 ), as well as concomitant diseases associated with a decrease in blood supply to the mucosa, such as heart failure HF (OR 6.1; 2.316.0;p=0.0002), AAA (OR 9.3; 2.534.2;p=0.0008) and APA (OR 2.3; 0.985.5;p=0.05) turned out to be independent predictors of UGI bleeding. The frequency of AAA among those who underwent UGI bleeding was 19.6% (in patients without bleeding 1.4%;p0.001). 90.2% of patients with UGI bleeding received PPI; the frequency of UGI bleeding in patients receiving pantoprazole and omeprazole did not differ significantly. After UGI bleeding, rebleeding rate was 7.8%, thrombotic events (TE) rate 31.4%, mortality rate 17.7% for 30 days, 19.4% for 1 year and 35.3% for the entire observation period. The predictors of deaths were AAA (OR 92.5; 7.7107.9;p0.0001), APA (OR 4.2; 1.0317.2;p=0.045) and HF (OR 34.5; 8.5140.6;p0.0001). The worst prognosis was expected for patients who underwent UGI bleeding and thrombotic events: 2/3 of these patients died. Conclusion.In a prospective analysis of patients with stable CAD, we identified UGI bleeding was a significant risk factor for late thromboembolism and death, compared with patients without bleeding. Predictors of UGI bleeding and poor prognosis are factors that indicate atherothrombotic burden abdominal aortic aneurysm, peripheral atherosclerosis and HF.

Aim. To optimize the upper gastrointestinal bleeding (UGIB) risk scale in patients Material and methods. The UGIB risk scale was developed based on the with chronic coronary artery disease (CAD) receiving long-term antiplatelet therapy. prospective REGistry of long-term AnTithrombotic TherApy-1 REGATTA-1(ClinicalTrials.gov Identifier: NCT04347200). The registry includes 934 patients with stable CAD (men, 78,6%; median age, 61±10,7 years), 76% of whom were included after elective percutaneous coronary interventions and received dual antiplatelet therapy for 6-12 months. After a UGIB episode, patients were prescribed proton pump inhibitors. The 2015 European Society of Cardiology (ESC) scale was used for assessing the UGIB risk. In addition, we evaluated the ultrasound data on atherosclerotic burden (abdominal aorta and peripheral arteries).Results. The median follow-up was 2,5 years [1,1-14,7 years]. The incidence of UGIB was 1,9 cases per 100 patient/years. Recurrent UGIB episodes and thrombosis was recorded in 13,7% and 31,4%, respectively. Based on the results of a multivariate logistic regression, a novel scale for assessing the UGIB risk (REGATTA) has been developed. In accordance with the odds ratio, points were assigned for each independent risk factor (RF): age ≥80 years — 3 points, prior gastric erosion, peptic ulcer disease or UGIB — 3 points for each RF, anticoagulation therapy — 4 points, non-steroidal antiinflammatory drug therapy — 2 points. The atherosclerotic burden (peripheral atherosclerosis and/or abdominal aortic aneurysm; 2 points) and heart failure (in most cases after a myocardial infarction; 2 points) were marked as a new independent predictor. The cutoff value (≥4 points) was determined, reflecting the high UGIB risk (sensitivity, 80,4%; specificity, 84,5%). The REGATTA scale was more powerful than the traditional 2015 ESC scale: AUC of 0,88, (95% confidence interval, 0,86-0,9) vs AUC of 0,79, (95% confidence interval, 0,760,82) (p=0,04).Conclusion. The identified UGIB predictors (atherosclerotic burden and heart failure) and the developed REGATTA scale made it possible to improve the prognosis and prevention of UGIB in patients with stable CAD receiving long-term antiplatelet therapy.

The article presents the results of using a combination of PPI (pantoprazole) and UDCA for the treatment of erosive esophagitis induced by mixed reflux in patients with coronary artery disease.A total of 62 patients with EGDS-proven erosive esophagitis were enrolled in the study. The patients were divided into two groups: the active treatment group (ATG) which included 34 patients with erosive reflux esophagitis and control group (CG), which included 28 patients with erosive reflux esophagitis without CAD. The patients of both groups received IPP (pantoprazole) 80 mg/day and UDCA at a dosage of 15 mg/kg/day for 12 weeks. (84 days).The study showed that complete epithelialization of esophageal mucosa defects was detected in 100% of ATG patients by Day 84 of therapy, the same was achieved in CG patients by Day 56 of the basic course of therapy.The treatment of EE induced by mixed reflux with a combination of PPI (pantoprazole) at a dose of 80 mg/day and UDCA at a dosage of 15 mg/kg/day was efficient in patients with GERD and CAD as a basic course of therapy for not less than 84 days. An effective dose of UDCA for maintenance therapy is 5 mg/kg/day in combination with PPI at a daily dose of 40 mg for not less than 2 months.
