BACKGROUND: After an acute atherosclerotic cardiovascular event, high-intensity lipid-lowering therapy (LLT) is needed to reduce recurrence risk. This study aimed to describe LLT prescription patterns and LDL-C levels change after non-fatal acute coronary syndrome (ACS) events and to determine if the recommended goals for LDL-C levels were achieved.
METHODS: Retrospective cohort study using electronic health records (EHR) of Unidade Local de Saúde de Matosinhos between 2015 and 2023. Participants were adults aged 40-80 years, with a non-fatal ACS hospitalization between 2016 and 2022 (index date); ≥1 general practice appointment in the three years before ACS; and one-year follow-up post-ACS. Sub-analyses focused on gender, age (<and ≥65 years), and whether patients met LDL-C control (55 mg/dL) at one-year post-ACS.
RESULTS: Of 544 patients, 270 (49.6 %) were under 65 years, and 164 (30.1 %) were females. Before the ACS, 71.1 % of men and 56.7 % of women had no previous LLT prescription and younger patients showed poorer LDL-C control (132(IQR 64)mg/dL) than older patients (102(IQR 50)mg/dL). One-year post-ACS, only 11.3 % of males and 8.5 % of females met LDL-C target. The proportion of patients without LLT decreased from 66.7 % at baseline to 13.6 % post-ACS. High-intensity LLT prescriptions increased from 2.4 % to 16.5 %, while moderate-intensity LLT remained predominant (65.8 %). Still, 89.5 % of patients had uncontrolled LDL-C levels.
CONCLUSION: Despite initiating/intensifying LLT, one year after ACS most patients did not achieve LDL-C goals. This indicates a significant gap in guideline implementation in clinical practice.
