Objectives This real-world study investigated the changes of lipid lowering therapy (LLT) usage in patients with high or very high cardiovascular (CV) risk in the UK and the group of all other European countries in the SANTORINI study up to 1 year from baseline and the impact this treatment had on the attainment of low-density lipoprotein cholesterol (LDL-C) risk-adjusted goals set by the National Institute for Health and Care Excellence (NICE) and those in the 2019 European Society of Cardiology (ESC)/European Atherosclerosis Society (EAS) dyslipidaemia guidelines. Design Secondary analysis of the SANTORINI dataset (an international, prospective, observational, non-interventional study ( NCT04271280 )). Setting Primary and secondary care centres in the UK and the group of other European countries (Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy, the Netherlands, Portugal, Spain, Sweden and Switzerland). Participants 663 UK patients with high and very high CV risk were included in this analysis and 8502 from the group of other European countries. Of these, 380 UK patients and 6830 from the group of other European countries had LDL-C information available at baseline and 1-year follow-up. Primary outcome measures The primary objectives were to describe patients’ lipid management, LDL-C levels at 1-year follow-up and their attainment of 2023 NICE (≤2.0 mmol/L) and 2019 ESC/EAS LDL-C 2019 guideline-recommended LDL-C goals (<1.4 mmol/L for very high-risk patients and <1.8 mmol/L for high-risk patients) within this time frame. Results Over the course of 1-year follow-up, the overall proportion of UK patients on no LLT reduced from 20.4% at baseline to 7.1%, similar to that observed in the group of other European countries (baseline–20.9%, 1 year–3.0%). The proportion of UK patients receiving LLT monotherapy increased from 74.8% at baseline to 84.9%, higher at both time points than that observed for the group of other European countries (baseline: 52.0%, 1 year: 55.0%). The use of any combination therapy increased slightly from baseline to 1 year in the UK overall cohort (4.9% vs 7.1%) and overall in the group of all other European countries, the cohort increased from baseline (27.1%) to 1 year (40.2%). Overall, mean (SD) LDL-C levels in the UK were 2.5 (1.2) mmol/L at baseline and 2.1 (1.0) mmol/L at 1 year and for the group of other European countries were 2.4 (1.2) mmol/L at baseline and 2.0 (0.9) mmol/L at 1 year. The overall proportions of UK patients achieving the UK NICE treatment goal and ESC/EAS 2019 guidelines at baseline versus 1-year follow-up were 40.3% vs 52.6% and 22.9% vs 32.9%, respectively; 21.1% and 30.9% of patients in the group of other European countries achieved the ESC/EAS 2019 guidelines at baseline and 1-year follow-up, respectively. Conclusions In this UK-focused analysis of the SANTORINI study, use of LLT increased modestly over 1 year, accompanied by a reduction in average LDL-C levels. However, mean LDL-C remained above the NICE goal, and attainment of both NICE and ESC/EAS LDL-C thresholds remained suboptimal. The findings highlight continued opportunities to optimise lipid management in UK clinical practice, including the potential for broader use of combination therapies.
