Introduction Atherosclerotic cardiovascular disease (ASCVD) is the leading cause of mortality in Italy, accounting for 22% of total deaths. Lowering low-density lipoprotein cholesterol (LDL-C) levels reduces the risk of cardiovascular (CV) events; thus, lipid-lowering therapy (LLT) is the first-line treatment for patients with ASCVD and hypercholesterolaemia. However, many patients with ASCVD fail to reach LDL-C treatment thresholds, leaving them at greater risk of CV events. Inpatient care accounts for 51% of total expenditure on cardiovascular disease in the European Union, but healthcare resource utilization (HCRU) data for ASCVD in Italy is limited. Methods The study analysed healthcare claims data for 17,881 patients with acute coronary syndrome, ischemic stroke or peripheral artery disease from the Umbria 2 and Marche regions of Italy. LLT treatment patterns and CV event rates were collected and HCRU estimated in the year before and after the index event. Results High-intensity LLTs were prescribed to 44.3% of patients and 49.6% received moderate-/low-intensity LLTs during the 6 months after the index event. The first year CV event rate was 18.0/100 patient-years for patients receiving high-intensity LLTs and 17.2/100 patient-years for those on moderate-/low-intensity LLTs. Higher costs were associated with patients untreated with LLT 6 months post-index event (€8323) than patients prescribed high-intensity (€6278) or moderate-/low-intensity LLTs (€6270). Hospitalization accounted for most of the total costs. Conclusions This study found that CV events in secondary prevention Italian patients are associated with substantial HCRU and costs. More intensive LDL-C lowering can prevent CV events, easing the financial burden on the healthcare system.

Introduction Patients with a history of myocardial infarction (MI) are at very high risk of subsequent cardiovascular events. This study evaluated the association of treatment intensity and adherence to lipid-lowering therapies (LLT) with major adverse cardiovascular events (MACE) among post-MI patients in Germany. Methods We carried out a retrospective cohort study using German health claims data (2010–2015). We included patients ≥ 18 years, with a history of MI and who started an LLT (statin and/or ezetimibe), between 2011 and 2013. The follow-up period started 1 year after the second LLT prescription and continued until MACE, all-cause death or December 31, 2015, whichever occurred first. Treatment intensity was classified based on expected low-density lipoprotein cholesterol reduction; adherence was measured by the proportion of days covered using prescription data. A combined adherence-adjusted intensity variable was created by multiplying intensity and adherence. We used Cox proportional hazards models to control for age, sex, Charlson Comorbidity Index and other cardiovascular risk factors at baseline. Results A total of 14,944 patients were included. Mean age was 66.7 (SD = 13.0) years; 68.7% of patients were men. Each 10% increase in treatment intensity, adherence, or adherence-adjusted intensity was associated with a decrease in the risk of MACE of 17% (HR = 0.83, 95% CI 0.79–0.87), 5% (HR = 0.95, 95% CI 0.94–0.97), and 14% (HR = 0.86, 95% CI 0.83–0.90), respectively. Conclusions Higher treatment intensity and/or adherence of LLT was associated with significantly lower risk of MACE in post-MI patients. Strategies to tailor intensity to patient profiles and improve adherence could reduce the risk of cardiovascular events.
