Objective To explore the diagnostic value of gastric gontrast ultrasound in gastric non-neoplastic diseases in patients with coronary heart disease. Methods Gastric contrast ultrasoundwas used to examine the patients diagnosed with coronary heart disease and gastric or epigastric discomfort in our hospital, and the results were retrospectively analyzed according to the results of gastroscopy and pathological. Results Compared with the results of gastric contrast ultrasound and gastroscopy and pathology, the coincidence rate of gastric polyp and gastric ulcer examination was consistent in benign gastric disease(Kappa=0.879、Kappa=0.913), and the coincidence rate of gastritis examination was average(Kappa=0.611).Conclusion Gastric contrast ultrasound is a convenient, simple and non-invasive examination method for benign gastric disease in patients with coronary heart disease. Its diagnostic performance in diagnosing benign gastric disease such as gastric polyps and gastric ulcers is comparable to that of gastroscopy. When patients with coronary heart disease do not have the subjective and objective conditions for gastroscopy, it can provide another option for the clinical examination of gastric lesions.
