Achieving Lower LDL-C Levels After a Recent Myocardial Infarction Might Be Associated with Lower Healthcare Resource Use and Costs in Spain.

Introduction: There is little evidence on the relationship between achieved low-density lipoprotein cholesterol (LDL-C) levels and costs in patients on lipid-lowering therapy (LLT). We described healthcare resource use and costs (direct and indirect) by achieved LDL-C in patients receiving LLT after a recent myocardial infarction (MI) in Spain. Methods: This was a retrospective observational study of anonymized electronic medical records from seven regions in Spain (BIG-PAC^® database; n = 1.9 million). Eligible patients were adults (≥ 18 years) hospitalized for an MI between January 2015 and December 2017, treated with a statin and/or ezetimibe, and having recorded LDL-C values at baseline and during follow-up. Healthcare resource use and direct and indirect costs (in 2018, €) were described by achieved LDL-C levels during a follow-up of 18 months. Results: Of 6025 patients (mean age, 69.7 years; 77% male), only 11% achieved LDL-C goals as defined in the 2016 ESC/EAS guidelines (< 70 mg/dL), and just 1% reached the lower target (< 55 mg/dL) in the current 2019 guidelines. Achieving lower LDL-C levels translated to lower healthcare resource use and costs. Mean total (direct and indirect) costs ranged from €5044 for patients with LDL-C < 55 mg/dL to €7567 for patients with LDL-C ≥ 130 mg/dL. Conclusion: Very few patients achieved recommended LDL-C goals despite using LLT. Achieving lower LDL-C levels after an MI might be associated with lower healthcare resource use and costs. Use of more intensive LLT, leading to greater reductions in LDL-C, could therefore be beneficial both from a clinical and an economic perspective. [ABSTRACT FROM AUTHOR]
