Abstract
Background Recent guidelines on acute coronary syndromes (ACS) recommend initiating lipid-lowering therapy (LLT) as early as possible to obtain >50% low-density-lipoprotein cholesterol (LDL-c) reduction and an LDL-c < 1.4 mmol/l. Methods A multinational European survey study of ACS patients between 2021-2022 and acquired data on LLT and lipid levels on admission and during 1-year posthospitalization. We compared plasma lipid changes and adherence to post-ACS lipid targets across two in-hospital LLT groups: high-intensity statin (HIS) monotherapy (mono-HIS) and a combination of HIS and ezetimibe (combo-HIS). Results Of 286 patients, 268 (94%) received in-hospital HIS and were included in the final analysis. Patients (median age: 61.1 years) had a median baseline LDL-c of 3.3 mmol/l. Mono-HIS was the predominant in-hospital LLT (72.4%). In-hospital combo-HIS was administered in 27.6% of the cases. Patients from high-income countries (n = 141) were more likely to receive in-hospital combo-HIS than patients from middle-income countries [n = 127; 38.3% vs. 15.7% patients, P < 0.001). One-year post-ACS, 50 (26.5%) patients from the mono-HIS group received ezetimibe. The target of LDL-c <= 55 mg/dl was reached in 85 patients (31.7%), without significant difference between study groups [mono-HIS: 56 (28.9%) and combo-HIS: 29 (39.2%) patients, P = 0.10]. The target of >50% reduction was achieved more frequently among the combo-HIS group than in the mono-HIS group (50.0% vs. 29.9%, respectively, P = 0.002). Conclusion LDL-c targets were achieved in less than half of the patients post-ACS, regardless of the LLT regimen. Combo-HIS was initiated in-hospital post-ACS in only 28% and was associated with greater LDL-c reduction compared to a staged approach of mono-HIS with up-titration at follow-up.
