The objective of this study is to investigate the effectiveness of in-hospital initiation of alirocumab combined with statin ± ezetimibe on major cardiovascular events (MACE) in Chinese ACS patients. The main question it aims to answer is:
whether early initiation PCKS9i in hospital could reduce recent cardiovascular event risk in Chinese ACS patients in real-world setting.
Data from CCA Database-Chest Pain Center were screened for all ACS patients from 01-Jan 2021 to 31-Dec 2023. Patients diagnosed with STEMI, NSTEMI or UA at admission were identified at the first step. Then, for intervention group, patients who received alirocumab 75mg combined with statin ± ezetimibe during the ACS hospitalization (including the discharge date) will be included; for control group, patients who received statin ± ezetimibe during the ACS hospitalization will be included. All enrolled patients were required to have at least one documented follow-up visit.
Patients diagnosed with Acute Coronary Syndrome (ACS) upon hospital admission.
Patients aged 18 years or older.
Patients who received Alirocumab 75 mg in combination with statin therapy ± Ezetimibe as the intervention group, and those treated exclusively with statin therapy ± Ezetimibe as the control group, either during hospitalization or at discharge.
Patients with at least one follow-up record.
Patients who received Evolocumab treatment at any time.
Patients who received Inclisiran treatment at any time.
