Global burden of high-risk cardiovascular patients without prior myocardial infarction or stroke: VESALIUS-REAL - preliminary results from Germany

Abstract

Abstract Background Clinical trial data has shown that low-density lipoprotein cholesterol (LDL-C) lowering with PCSK9-inhibitors reduced cardiovascular (CV) endpoints in patients with established atherosclerotic cardiovascular disease (ASCVD). Intervening early in patients with high CV risk prior to myocardial infarction (MI) or stroke, while perceived to be less urgent, may result in larger public health benefits. The effect of evolocumab in this population is investigated in a phase-3 clinical trial (NCT03872401: Effect of Evolocumab in Patients at High Cardiovascular Risk Without Prior Myocardial Infarction or Stroke [VESALIUS-CV]). This observational study examines the global burden of VESALIUS-CV-like population in the REAL-World ("VESALIUS-REAL") in eight regions (Germany, Hong Kong, Japan, South Korea, Sweden, Taiwan, UK and US) using a unified protocol across multiple databases. The multi-database study is ongoing, and the current analysis focuses on characteristics of VESALIUS-CV like patients in Germany. Methods Eligibility criteria are shown in the Figure. Data were obtained from the German Disease Analyzer (2013-2022), a representative claims database from Germany. Criteria were aligned with the clinical trial, and real-world definitions were created using diagnosis and procedure codes. Results A total of 195,621 patients were included in the present analysis (Table). At baseline, the median age was 71 years (Q1-Q3: 64-79) and 48% of patients were women. Approximately two-thirds of patients had atherosclerosis (48.5% had coronary artery disease, 13.8% had cerebrovascular disease and 13.8% had peripheral artery disease) and 33.7% had high-risk diabetes mellitus (DM), defined as DM with microvascular complications or chronic insulin use. The median baseline LDL-C was 139 (Q1-Q3: 113-166) mg/dL [3.6 (2.9 - 4.3) mmol/L] and 110,867 patients (57%) had an LDL-C ≥130 mg/dL (≥3.4 mmol/L). Overall, 69% of VESALIUS-CV like patients were receiving no background LLT. Conclusions Despite having atherosclerosis and/or high-risk DM and LDL-C exceeding target thresholds, a large proportion of VESALIUS-CV like patients were not on any LLT in Germany. Final results from VESALIUS-REAL will be able to report if this treatment gap is also observed in other countries.
