Inclusion criteria
Inclusion criteria: 1.Age >= 60 years old (according to WHO/UN standards for the elderly, combined with domestic cardiovascular research conventions); 2. From January 1st, 2022 to December 31st, 2024, they were treated in the Department of Cardiology of our hospital; 3. Successfully received percutaneous coronary intervention (including balloon dilatation, stent implantation or both) during this hospitalization; 4. Have complete electronic medical record data, and be able to obtain the core variables required for calculating grace score and model construction.
Exclusion criteria
Exclusion criteria: 1. critical state: hospitalized due to cardiogenic shock, cardiac mechanical complications (such as ventricular septal perforation, papillary muscle rupture) and other critical states, or the expected survival time is very short (<24 hours); 2. severe complications: malignant tumor (expected survival time<1 year), end-stage liver disease, severe hematological system disease or immune system disease; 3. in hospital death: in hospital death occurred after PCI during this hospitalization; 4. lack of key data: the clinical key data (such as left ventricular ejection fraction (LVEF), the number of coronary artery lesions, troponin peak, etc.) are missing, so they cannot be used for model analysts; 5. non first admission: repeat admission within the statistical time window due to the same disease diagnosis (only included in the first admission record); 6. patients who are judged by the investigator as unsuitable for participating in this study.
