Lp(a) testing is available in this center and reimbursed. 2. Capacity to increase Lp(a) testing in relevant patient groups (according to the defined patient eligibility criteria). 3. Low and/or inconsistent Lp(a) testing rate(number of eligible patients tested for Lp(a)/number of eligible patients seen) \<15%. 4. Willingness to fulfill research requirements, e.g., repurposing existing clinic data for research etc. 5. Seeing a defined number of eligible patients per year based on the sample size required for the study. 6. Availability of local infrastructure and data interoperability.

Patients attending at least one SOC visit during the pre-defined time intervals (12 months prior to index date and 0-6 months, 7-12 months and 13-24 months post-index). 3. Previous Lp(a) testing: 1. Patients with an Lp(a) test recorded before the index date will be included in the baseline assessment, which covers the 12 months prior to the index date. 2. For post-index assessments at 6-, 12- and 24-months after the index date, patients with an Lp(a) test recorded before the index date will be excluded. 4.
