From the Guidelines

The patient's unusually high HDL of 100 mg/dL and borderline elevated LDL of 132 mg/dL, combined with non-compliance to medications and daily avocado consumption, necessitate a thorough evaluation of secondary causes of dyslipidemia and adherence to prescribed lipid-lowering therapy, as recommended by the 2013 ACC/AHA guideline on the treatment of blood cholesterol to reduce atherosclerotic cardiovascular risk in adults 1.

The patient's lipid profile is notable for the high HDL level, which may be influenced by the daily consumption of avocados, rich in monounsaturated fats known to increase beneficial HDL cholesterol. However, the LDL level, although not markedly elevated, remains a concern, especially given the patient's non-compliance with prescribed medications, which may include statins or other lipid-lowering agents. The presence of hyperkalemia suggests potential kidney dysfunction, which can impact lipid metabolism and should be addressed through appropriate testing and management.

Key considerations in managing this patient's lipid profile include:

  • Evaluating and addressing the cause of hyperkalemia, potentially through kidney function tests, as kidney dysfunction can affect lipid levels and metabolism.
  • Assessing for secondary causes of dyslipidemia, such as thyroid disorders, diabetes, or genetic hyperlipidemias, as recommended in the guideline 1.
  • Encouraging adherence to prescribed lipid-lowering medications, particularly statins, which are recommended for individuals with elevated LDL-C levels and are at risk for atherosclerotic cardiovascular disease (ASCVD) 1.
  • Continuing to promote heart-healthy lifestyle habits, including a diet rich in fruits, vegetables, and healthy fats like those found in avocados, as part of a comprehensive approach to reducing ASCVD risk.

Given the patient's profile and the guidelines provided, resuming prescribed medications and evaluating for secondary causes of dyslipidemia are crucial steps in managing the patient's lipid profile and reducing the risk of ASCVD, as emphasized by the 2013 ACC/AHA guideline 1.

From the Research

Potential Causes of HDL and LDL Levels

  • The patient's noncompliance to medication and daily consumption of avocado may be contributing factors to their HDL and LDL levels 2, 3, 4, 5, 6.
  • Avocado is known to have a positive effect on HDL levels, which may be contributing to the patient's high HDL level of 100 2, 3, 4, 5, 6.
  • The patient's LDL level of 132 may be due to their noncompliance to medication, as statins and ezetimibe have been shown to be effective in lowering LDL levels 2, 3, 4, 5, 6.

Effect of Ezetimibe and Atorvastatin on Lipid Levels

  • The combination of ezetimibe and atorvastatin has been shown to be effective in lowering LDL levels and raising HDL levels 2, 3, 4, 5, 6.
  • Ezetimibe has been shown to reduce LDL levels by 24% compared to baseline, with 93% of patients reaching their LDL cholesterol goals 2.
  • The combination of ezetimibe and atorvastatin has been shown to improve vascular endothelial function in high-risk patients with hypercholesterolemia 2, 3, 4, 5, 6.

Hyperkalemia

  • There is no direct evidence in the provided studies to suggest a link between the patient's hyperkalemia and their HDL and LDL levels 2, 3, 4, 5, 6.
  • However, it is possible that the patient's hyperkalemia may be related to their noncompliance to medication or other underlying health conditions 2, 3, 4, 5, 6.
