Lipid-lowering treatment and LDL-C goal attainment in high and very high cardiovascular risk patients: Evidence from the SANTORINI study-The Italian experience

Abstract

The SANTORINI study is an observational study that enrolled 9602 adult individuals at high or very high cardiovascular (CV) risk across Europe, aimed at providing information on the current status of the management of dyslipidaemias, in light of the most recent 2019 EAS/ESC guidelines.
Italy participated in the study with 1977 patients, 1531 (77.4%) of whom were classified at very high CV risk and 446 (22.6%) at high CV risk. Overall, in the Italian population, 79.31% of the patients had a history of atherosclerotic cardiovascular disease (ASCVD). At enrolment, the mean level of LDL-C in the total population was 98.4 mg/dL. LDL-C levels were lower in the very high-risk group (94.6 mg/dL) than in the high-risk group (111.4 mg/dL). Considering the therapeutic goals recommended by the most recent 2019 ESC/EAS guidelines (LDL-C <55 mg/dL or <70 mg/dL respectively in very high or high-risk patients, respectively), only 20.3% of the overall study population achieved such goals (19.9% of very high-risk patients and 21.8% of high-risk patients). About one-third of the patients included in the study (32.6%) were not prescribed any therapy, one-third received statin monotherapy (34.4%), and only one-third (33%) were taking combination therapy; these percentages were comparable in the two risk subgroups.
Based on the most recent 2019 ESC/EAS guidelines, the use of cholesterol-lowering therapies is not always optimal to achieve the therapeutic goals even in patients with very high CV risk. This means that about 80% of patients are far from the recommended therapeutic goals for their risk category.
