From the Guidelines
To solve MCQE1 questions on dyslipidemia, you should use the 2024 recommendations on the optimal use of lipid-lowering therapy in established atherosclerotic cardiovascular disease and following acute coronary syndromes, as outlined in the position paper of the international lipid expert panel (ILEP) 1. The criteria to focus on include the sound principles of LDL-C reduction, which emphasize the importance of early initiation, lower targets, and longer duration of therapy 1. Key aspects to consider are:
- The use of statin therapy and lipid-lowering combination therapy with non-statin drugs, such as ezetimibe and PCSK9 inhibitors, for patients with established atherosclerotic cardiovascular disease (ASCVD) or acute coronary syndromes (ACS) 1.
- The recommendation for intensification of statin therapy and addition of ezetimibe if treatment targets are not met, and the consideration of PCSK9 inhibitors if LDL-C goals are not achieved despite maximally tolerated statin therapy and ezetimibe 1.
- The potential benefits of immediate initiation of lipid-lowering combination therapy in high-risk patients, including those with ACS, to rapidly achieve treatment targets and reduce the risk of recurrent events 1. It is essential to understand the different treatment approaches, including the use of monotherapy versus combination therapy, and the importance of individualizing treatment based on patient risk and response to therapy 1. Additionally, familiarity with the side effects and contraindications of lipid-lowering medications, as well as special considerations for specific populations, is crucial for answering questions on dyslipidemia management 1.

Guidelines for Dyslipidemia Management
To solve MCQE1 questions on dyslipidemia, it is essential to refer to the latest guidelines for cholesterol management. The following criteria can be used:
- Statins as first-line therapy for primary and secondary prevention of atherosclerotic cardiovascular disease (ASCVD) 2, 3
- Ezetimibe as an additional agent to reduce LDL cholesterol levels and decrease ASCVD risk when added to statin therapy 2, 3, 4
- Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, such as alirocumab and evolocumab, to lower LDL cholesterol levels and reduce ASCVD risk in high-risk patients 2, 3, 5
- Bempedoic acid as an alternative agent to reduce hepatic cholesterol synthesis and lower LDL cholesterol levels 3
- Combination therapy with statins and ezetimibe or PCSK9 inhibitors for high-risk patients who are not achieving treatment goals on a maximum tolerated dose of a statin alone 4, 6, 5
Key Considerations
When evaluating the efficacy and safety of different lipid-lowering therapies, consider the following:
- Percentage change in low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC), triglycerides (TG), and high-density lipoprotein cholesterol (HDL-C) as efficacy evaluation metrics 6
- Incidence of adverse events as safety evaluation metrics 6
- Patient-specific factors, such as statin intolerance, side effects, and adherence issues, when selecting a lipid-lowering therapy 3, 6
