Background And AimsThe criteria for the use of proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) more restrictive than those approved were established in Catalonia by the Health System (CatSalut) to improve their efficiency, with different LDL-C values from which to start treatment according to risk factors. The aim of the study is to analyse adherence to these criteria and results.MethodsA retrospective study of patients treated with PCSK9i at Vall d'Hebron University Hospital between 2016 and 2021 was performed using data from the Registry of Patients and Treatments and medical records. The degree of agreement with the CatSalut criteria, LDL-C-responders (decrease ≥30%), cardiovascular events and discontinuations were analysed.ResultsA total of 193 patients treated with PCSK9i were followed for a median of 27 months (IQR 23). The median age was 61 (IQR 15); 62.7% were men. Seventy percent of the patients had non-familial hypercholesterolemia. Treatment was for secondary prevention of cardiovascular disease in 82.4% of cases. The median LDL-C decreased from 139 (IQR 52) to 59 (IQR 45) mg/dL. The percentage of LDL-C reduction was 61.0% (IQR 30). In 72.5% of patients, all CatSalut criteria for starting treatment were met. The rate of responders was 85.4%. During follow-up, 19 patients (9.8%) had a cardiovascular event, and 15 (7.7%) discontinued treatment, in two cases due to toxicity.ConclusionPCSK9i were used according to CatSalut criteria in three out of four cases. In this high-risk population, incidence of cardiovascular events was similar to that in clinical trials.Copyright © 2024 Elsevier España, S.L.U. All rights reserved.
