Hyperlipidemia Flashcards
Increased levels of lipids in the blood, including Cholesterol and Triglycerides.
Hyperlipidemia
Makes Lipoproteins less dense.

How is Hyperlipidemia typically diagnosed?
Labs
According to the AHA, when should you screen for Hyperlipidemia?
Adults 20+ years old
How often should you repeat screening for Hyperlipidemia?
Average or Low Risk = Every 5 Years
High Risk = Every Year
What should individuals without Cardiovascular Disease have calculated?
10-Year-Risk of Cardiovascular Disease
Individuals with a LDL of what should be treated regardless of the 10-Year-Risk.
LDL > 190 mg/dL
What is the single best test for additional risk stratification of Cardiovascular Disease?
Coronary Artery Calcium Score
(Non-contrast Cardiac CT)
Takes 10-15 minutes
What is almost always the first-line therapy for Hyperlipidemia?
Statins
The 2018 AHA Multi-society Guidelines defines four groups of patients who would benefit for STATIN medications. Name those groups.
- Atherosclerotic Cardiovascular Disease
- LDL > 190
- Age 40 - 75 with Diabetes + LDL ≥ 70
- Age 40 - 75 without ASCVD or Diabetes and LDL of 70-189 + CVD Risk of ≥ 7.5%
Medications that inhibit the rate-limiting enzyme in the formation of cholesterol.
Statins (HMG-CoA Reductase Inhibitors)
What are the High Intensity Statins?
