ABSTRACT
OBJECTIVE: To reveal the clinical, morphological and pathogenic features of gastroduodenal erosions and ulcers in unstable angina. METHODS: 135 patients with unstable angina were examined and divided into 2 groups, depending on the presence of a pathological process in the gastroduodenal zone. The state of microcirculation in the tissues of the gastroduodenal zone, secretory and motor function of the stomach were estimated by complex of techniques, adapted to the severity of the patients. RESULTS: It is found that the pathological process in the gastroduodenal zone in patients with unstable angina was presented primarily by acute erosions, less - acute ulcers or recurrent peptic ulcer disease. In this case, the leading symptom of acute erosions was dyspepsia, that as a rule prevailed over the indistinct abdominal pain, and often disappeared in the first few days of treatment. Clinical picture of acute ulcers was determined by gastric dyspepsia and was often combined with abdominal pain and symptoms of gastrointestinal bleeding. The recurrence of peptic ulcer disease was characterized by the combination of moderate abdominal pain, often with migration in retrosternal and cardiac area and loss of circadian rhythm inherent in anthro-duodenal ulcer localization, and dyspeptic disorders. The severity of symptoms of ulcerous process was gradually decreased with time, but in most patients, they had remained by the end of the 2nd week of treatment. The basis of development of erosions and ulcers in unstable angina were the focal mainly thrombohaemorrhagic disorders of the terminal blood flow in the gastroduodenal mucosa. Its were combined with changes in the functional state of the stomach, manifested with an increase activity of acid-peptic factor, reduced production of gastromucoproteins, hypomotor dyskinesia and discoordination of anthro-duodenal propulsion on the hypotonic type. CONCLUSION: Erosive and ulcerative lesions of gastroduodenal zone in unstable angina have a number of clinical and pathogenetic features that should be considered in the process of diagnosis and treatment.
