However, few studies of routine clinical practice have been conducted to analyse and compare the efficacy and safety of the two drugs. Methods: Retrospective observational study of patients treated with a PCSK9 inhibitor in five hospitals in Andalusia (southern Spain). Baseline demographic and clinical data, LDL-cholesterol levels and the occurrence of MACEs during the follow-up period were recorded. Results: A total of 141 patients were included in the study: 90 were treated with alirocumab and 51 with evolocumab. The patients' mean age (IQR) was 58 (11) years and 58 (41%) were women. The most frequent concomitant medications were statins, 94 (66.7%), followed by antiplatelet therapy (66%) and ezetimibe (65.2%). The median (IQR) follow-up period was 18 (18) months, with 18 (24) for alirocumab and 11 (18) for evolocumab. At the six-month follow-up visit, LDL-cholesterol values had decreased to pre-treatment levels and remained significantly decreased (penAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/EvolocumabAlirocumabPCSK9iHypercholesterolemia familiarCardiovascular diseaseStatins intoleranceHeterozygous familial hypercholesterolemiaStatin therapyDouble-blindEvolocumabManagementEzetimibeTrialEffectiveness and safety of PCSK9 inhibitors in real-world clinical practice.
