Effect of In-hospital Initiation of PCSK9i on Clinical Outcomes in Chinese ACS Patients: A Database-based Retrospective Analysis
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.
