ABSTRACT
OBJECTIVE: To explore the safety and assess the cardiovascular impact of early in-hospital administration of PCSK9 inhibitors in patients with acute coronary syndrome (ACS).
METHODS: A systematic search of PubMed, Web of Science, and Embase databases was conducted for studies involving the use of PCSK9 inhibitors in ACS patients from inception to October 2023. Two independent researchers screened the literature, extracted data, and assessed the risk of bias in the included studies. Meta-analysis was performed using STATA 16.0 software.
RESULTS: Nine studies, encompassing a total of 2896 ACS patients, were included in the analysis. When compared to statin monotherapy, early administration of PCSK9 inhibitors during hospitalization for ACS proved effective in reducing the incidence of major adverse cardiovascular events (MACEs). This encompassed a decrease in coronary revascularization [Relative Risk (RR) = 0.78, 95% CI (0.62, 0.98), P < 0.05], recurrent ACS [RR = 0.62, 95% CI (0.42, 0.94), P < 0.05], readmissions due to unstable angina [RR = 0.71, 95% CI (0.59, 0.85), P < 0.01], and strokes [RR = 0.31, 95% CI (0.09, 1.04), P = 0.058]. There was no significant difference in the incidence of death between the two groups.The use of PCSK9 inhibitors notably hastened the reduction of LDL-C, TG, and Non HDL-C levels in the short term. Additionally, it increased HDL-C levels and the number of individuals meeting LDL-C compliance criteria. Importantly, the risk of adverse drug events, such as ALT increase >3xULN, allergies, and musculoskeletal pain, did not significantly elevate with PCSK9 inhibitor use.
CONCLUSION: The early administration of PCSK9 inhibitors has been found to safely and effectively lower diverse lipid levels in patients with ACS. This reduction is associated with a noteworthy decrease in MACEs, encompassing revascularization, recurrent ACS, and hospital readmissions.
