The Efficacy and Safety of Proton Pump Inhibitor ( in Patients With Moderate Bleeding Risk and Coronary Artery Disease Undergoing Percutaneous Coronary: A Randomised, Open ,Compared With Control
Among patients who performed percutaneous coronary intervention (PCI) in patients with coronary artery disease (CAD), enrollment is performed in patients with moderate risk in gastrointestinal risk assessment indicators. After obtaining the consent form, patients are randomly assigned to the gastric acid secretion inhibitor group and the non-dose group.
Researchers and subjects proceed with the treatment group assignment, treatment-group assignment uses a random number table and the assigned drug is disclosed. Random checks are generated by statisticians and managed by the researchers.
In the test group, the incidence of gastrointestinal clinical events in DAPT patients is expected to be low while taking PPI, but there is a burden of PPI costs. In the case of the control group, the burden of PPI costs is reduced, but there is a possibility that the incidence of clinical events may occur, although it is a small number. Subjects in the test group will take DAPT for at least 6 months from the time of registration, and NSAIDs drugs or steroids and NOAC or warfarin should be prohibited as combination taboo drugs when participating in the study. Data will be collected during normal medical procedures and will be checked through an endoscope in case of upper gastrointestinal bleeding
Purpose : This study compares gastrointestinal and cardiovascular events with coronary artery disease (CAD) patients who underwent percutaneous coronary angioplasty in patients with moderate gastrointestinal bleeding risk with use of dual antiplatelet drugs (DAPT), especially controversial use of prophylactic acid secretion inhibitors, and attempts to confirm the effectiveness and safety of gastric acid secretion inhibitors
Background : DPAT is a standard treatment in patients with CAD with percutaneous coronary intervention (PCI). However, it is important to consider the GI bleeding risk when using DAPT and to determine whether Proton Pump Inhibitor (PPI) should be prescribed to prevent such accidents. DAPT, or aspirin and P2Y12 receptor inhibitor, complementarily reduce platelet activation and aggregation and consequently reduce the progression of coronary thrombosis.
We have reported whether PPI use is associated with ischemic events or mortality in patients with DAPT up to date, but we have shown conflicting results depending on the type of study conducted. Observational studies generally show that PPI increases all-cause and cardiovascular mortality, angina and stroke, while RCT studies show that it does not. This difference can be explained by the selection bias. This is because observational studies attempt to reduce selective bias through correction of basic patient characteristics, but unmeasured differences in underlying variables continue to affect the results.

After obtaining the consent form, patients are randomly assigned to the gastric acid secretion inhibitor group and the non-dose group.
