In summary, age, ALB, FFA, ApoA1 and GLU are independent factors for MACE during hospitalization in CHD patients, and a nomogram model for MACE during hospitalization risk prediction in CHD patients constructed based on the above factors has good discrimination, calibration,and clinical effectiveness and can be used as an effective tool for early clinical prediction of in-hospital MACE risk in CHD patients. The gene discussed is APOA1; the disease is coronary artery disorder.
