Inclusion criteria

Inclusion criteria: 1. Patients with coronary artery disease who were hospitalized and underwent PCI were selected for the study, aged 18 to 80 years, with no restriction on gender; 2. They met the diagnostic criteria for coronary atherosclerotic heart disease, with at least 1 diseased vessel stenosis >50% on imaging; 3. There was no contraindication to coronary intervention, and at least 1 diseased vessel underwent coronary intervention or treatment during the procedure.

Exclusion criteria

Exclusion criteria: 1. Unstable clinical status, unstable hemodynamic or electrocardiographic monitoring, uncontrolled arrhythmias, and those with very high early mortality in clinical assessment; 2. Severe renal insufficiency, defined as an estimated glomerular filtration rate <30 mL/min/1.73 m^2; 3. Those who are currently self-administering medications/healthcare products of unknown composition that have been ineffectively discouraged by physicians; 4. Patients with a life expectancy of no more than 1 year or causing clinical follow-up; 5. Patients with malignant tumors or malignant systemic diseases that require treatment, severe anemia, or severe infections that are difficult to correct and control; 6. Pregnant women, for women with childbearing potential (age less than 50 years, not menopausal or last menstrual cycle less than 12 months prior to screening), women who have not undergone tubal ligation, ovarian or hysterectomy, pregnancy must be excluded prior to inclusion in this study; 7. Patients who are considered by the investigator to be inappropriate for the clinical trial for patients.
