1075 Use of Lipid-Lowering Combination Therapies in Santorini Study: Evidence From Italian Cohort

Abstract

The SANTORINI registry is an observational study that aims to evaluate the management of patients with high and very high cardiovascular (CV) risk in clinical practice, collecting data at enrolment and after 12 months. Italy participated in this study with 1531 patients at very high risk and 446 at high risk. The scope of the present analysis was to investigate low-density lipoprotein cholesterol (LDL-C) goal attainment in patients who do not qualify for PCSK9 inhibitors (PCSK9i) (according to Italian reimbursement regulations) in Italian cohort, with focus on patients in secondary prevention. The current indications for PCKS9i charged to the National Health System in Italy in secondary prevention, are for patients aged ≤ 80 years with LDL-c levels ≥ 70 mg/dl in at least three detections despite therapy for at least 6 months with high intensity statin at the highest tolerated dose and ezetimibe or after a single LDL-C detection for recent myocardial infarction or multiple cardiovascular events or with demonstrated intolerance to statins and/or ezetimibe. At enrolment, a total of 509 (33.2%) of 1531 patients at very-high risk had an LDL-C level of less than 70 mg/dl. Of them, about half do not reach the LDL-C target. In particular, 34.4% takes statin monotherapy, and 50.3% of them do not reach the target. Even patients taking high-intensity statins as monotherapy reach the target in only 47.9% of cases, leaving more than half of patients with LDL-C levels between 55 and 70 mg/dl. Regarding combination therapy, statin and ezetimibe, patients taking this combination account for 26.9%, of these those taking the combination of moderate-intensity statin and ezetimibe reach the target in 56.7% of cases while those taking high-intensity statins and ezetimibe reach the target in 51.4% of cases. Our findings show that there is a proportion of patients with LDL-C below 70 mg/dl who do not qualify for PCSK9i who are not at target for LDL-C levels despite maximal therapy with statins and ezetimibe.
