Brief Summary

The dual antiplatelet therapy based on aspirin plays an important role in the treatment of patients with coronary heart disease. Although aspirin is widely used and effective, it has many limitations in the long-term including increased risk of bleeding. In patients with coronary heart disease and gastroesophageal reflux disease, the symptoms of gastroesophageal reflux are usually aggravated after the application of aspirin. As an antiplatelet drug, indobufen can reversibly and selectively inhibit platelet cyclooxygenase-1 (COX-1), thereby blocking the synthesis of thromboxane B2 (TXB2) and exerting its antiplatelet effect, and it does not affect the production of prostaglandins and endothelial prostacyclins in gastrointestinal mucosa. It has less gastrointestinal injury and lower risk of bleeding. This project is to study the effects of indobufen or aspirin on gastric acid secretion and gastroesophageal reflux in patients with coronary heart disease and gastroesophageal reflux disease treated with dual antiplatelet therapy.
