AIM
To study the clinical features of inflammatory and atrophic changes (IAls) in the gastroduodenal zone (GDZ) in people with varying severity of chronic heart failure (CHF) associated with coronary artery disease (CAD) and to determine gastric secretion, local microcirculation, and the presence of Helicobacter pylori.

SUBJECTS AND METHODS
Seventy-four patients with CHF and gastric duodenal (GD) IAls who were divided into 2 groups according to its severity were examined. The specific features of impaired gastric secretory function and blood flow in the GD mucosa and its contamination with H. pylori were elucidated.

RESULTS
GD IAls were ascertained to be mainly focal in the patients with Stages I-Ila CHF and focal or diffuse in those with Stages IIb-III. According the clinical findings, these changes were generally shown in the concurrence of transient and unstable (in early- stage circulatory insufficiency) and prolonged and persistent (during severe congestive events) phenomena. The development of IAls in the GDZ was linked to its thrombohemorrhagic microcirculatory disorders, the severity of which increased as the symptoms of CHF progressed. In Stages I-Ila circulatory insufficiency, this was accompanied by the normal activity of acid-peptic factor, by the decreased production gastromucoproteins, and, in 58.3% of cases, by H. pylori. The patients with Stages IIb-III showed the suppressed production of all constituents of gastric secretion and H. pylori in 63.2% of cases.

CONCLUSION
The clinical manifestations and mechanisms of GD IAIs in CHF associated with CAD have a number of substantial differences in relation to its severity, which should be kept in mind when elaborating therapeutic and diagnostic measures.
