A risk prediction model for gastrointestinal bleeding in coronary heart disease patients undergoing dual antiplatelet therapy after percutaneous coronary intervention

The risk factors for gastrointestinal bleeding in CHD patients during DAPT after PCI include advanced age, chronic renal insufficiency, digestive tract disease history, myocardial infarction history, PCI procedure duration, creatinine clearance rate, and non-application of gastric mucosal protective agents. The ROC curve drawn based on the above factors can effectively predict gastrointestinal bleeding during DAPT. This model can be used to develop clinically targeted interventions aimed at preventing gastrointestinal bleeding and improving patients' prognosis.
