There is a rise in the rates of acute erosive gastropathies in patients with cardiovascular and other somatic diseases. The role of acute erosive gastropathy-induced hemorrhages in the tanatogenesis of these diseases is underestimated; the problems of their prevention, diagnosis, and treatment remained unsolved. Many factors, mainly acute or chronic ischemia of the gastroduodenal mucosa, as well as its age-related involution, Helicobacter pylori infection, reflux gastritis, multiple organ dysfunction, drug-induced damage, etc., which are implicated in the pathogenesis of acute erosive gastropathies in patients with cardiovascular and other somatic diseases, are summarized.
