What this Trial Is About

Patients with acute coronary syndrome (ACS) after Percutaneous Coronary Intervention (PCI) require routine treatment with dual antiplatelet (DAPT) treatment, but with the high risk of bleeding, gastrointestinal bleeding is the most common type of major bleeding. Helicobacter pylori (Hp) infection is a high-risk factor for gastrointestinal bleeding, with an incidence of about 50%. Foreign authoritative DAPT guidelines do not give individual guidance to Hp-infected patients. It is recommended that those with high bleeding risk should be combined with proton pump inhibitors (PPI), but long-term compliance with PPI is not ideal. Authoritative experts in China have agreed to recommend Hp detection and eradication therapy for DAPT patients, but loss of evidence. Vonoprazan is a novel potassium ion competitive acid blocker, based on Vonoprazan's dual Hp eradication therapy is simple and effective. Our team will conduct a multi-center, open-label, randomized controlled clinical trial using a non-inferior design to compare the combination of Vonoprazan + amoxicillin combined with pantoprazole (PPI) for 6 months after PCI on the bleeding events of the digestive tract.
