HOW TO REDUCE GASTROINTESTINAL BLEEDING RISK ON ANTICOAGULATION THERAPY IN NON-VALVULAR ATRIAL FIBRILLATION?

Abstract

Atrial fibrillation (AF) is a significant risk factor for stroke and systemic embolism. For prevention of these complications, most AF patients are indicated to take anticoagulants, that reduce the risk cardioembolic strokes, but increase the risk of bleedings, and the most prevalent are gastrointestinal (GIB).Aim. To assess the rate of pathological changes in esophagus, stomach and duodenum, predisposing for GID, in AF patient with higher risk of stroke and absolute indications for anticoagulation therapy.Material and methods. The analysis done, of case histories of hospitalized patients in the therapeutical university clinics, in the year 2016; of those — 263 with non-valvular AF. Among 222 patients with AF and higher risk of stroke, who had indications for anticoagulants, 103 underwent screening fibroesophagogastroduodenoscopy (FEGDS).Results. The FEGDS, performed in 103 patients with non-valvular AF and high risk of stroke, in 45,6% revealed diseases predisposing to GIB, including esophageal cancer — 1 (2,1%), gastric ulcer — 4 (8,5%), duodenal ulcer — 2 (4,3%), erosive esophagitis and reflux disease — 5 (10,6%), varicose veins of esophagus — 4 (8,5%), erosive gastritis — 31 (66,0%) and erosive duodenitis — 3 (6,4%). Combination of diseases was found in 10 (21,3%) patients.Conclusion. Patients with non-valvular AF and high stroke risk, before starting therapy with anticoagulants, it is aimworthy to perform FEGDS for on-time screening for esophageal, gastric, duodenal pathologies predisposing to GIB.
