    Background: The ODYSSEY OUTCOMES trial (NCT01663402) compared the effects of the pro- protein convertase subtilisin/kexin type 9 inhibitor alirocumab with placebo on major adverse cardiovas- cular events (MACE) in patients with recent acute coronary syndrome (ACS). Objective: We assessed efficacy and safety of alirocumab versus placebo according to sex and lipoprotein(a) level. Methods: This prespecified analysis compared the effects of alirocumab versus placebo on lipopro- teins, MACE (coronary heart disease death, non-fatal myocardial infarction, fatal/non-fatal ischemic stroke, unstable angina requiring hospitalization), death, total cardiovascular events, and adverse events in 4762 women and 14,162 men followed for a median of 2.8 years. In post-hoc analysis, we evaluated total cardiovascular events according to sex, baseline lipoprotein(a), and treatment. Results: Women were older, had higher baseline LDL-C levels (89.6 vs 85.3 mg/dL) and lipopro- tein(a) (28.0 vs 19.3 mg/dL) and had more co-morbidities than men. At 4 months, alirocumab lowered LDL-C by 49.4 mg/dL in women and 54.0 mg/dL in men and lipoprotein(a) by 9.7 and 8.1 mg/dL, respectively (both p < 0.0001). Alirocumab reduced MACE, death, and total cardiovascular events sim- ilarly in both sexes. In the placebo group, lipoprotein(a) was a risk factor for total cardiovascular events in women and men. In both sexes, reduction of total cardiovascular events was greater at higher base- line lipoprotein(a), but this effect was more evident in women than men (pinteraction = 0.08). Medication adherence and adverse event rates were similar in both sexes. Conclusions: Alirocumab improves cardiovascular outcomes after ACS irrespective of sex. Reduc- tion of total cardiovascular events was greater at higher baseline lipoprotein(a). ©2024 National Lipid Association. Published by Elsevier Inc.
