Real Life Lipid Management in Hospitals Not Participating in PENELOPE Trial - Control Population for PENELOPE

The recent PENELOPE study was designed to determine the effect of a protocolized, Dutch-, and ESC- guideline based strategy of stepwise intensified lipid management in patients at very high risk for ACS. In PENELOPE 22 Dutch non-academic hospitals, members of the WCN investigator network, implemented a protocol guided guideline approach in a consecutive cohort of very high-risk patients admitted for ACS over the period 01-01-2019 to 31-08-2020. Lipid values and medication strategy are collected at baseline (index ACS), and after three months and one year post ACS, in order to establish the percentage of patients on target (LDL). The current PENELOPE-CTRL study on the other hand, is designed to serve as a contemporary control cohort for PENELOPE. PENELOPE-CTRL is a retrospective observational study, creating a contemporary snapshot of real-life lipid management for secondary prevention in very high-risk patients. PENELOPE-CTRL will collect data in similar hospitals who did not participate in the PENELOPE trial. To allow comparison of these two strategies, protocol guided versus real life implementation of the cholesterol treatment guidelines, both cohorts include similar patients, and similar data will be collected (e.g., lipid lowering drugs, lipid panels) . Analysis will be done at similar time points. Comparing the real-life data from PENELOPE-CTRL with the data from the PENELOPE study will quantify the effect of a strategy of protocolized guideline-based lipid management with regards to the incidence of target LDL-C levels in very high-risk patients, 3 months and one year after hospitalisation with a myocardial infarction.
