T/F: Most individuals have no clinical signs of high cholesterol
True. Usually indicated in blood testing.
What values indicate an increase in CHD risk with high cholesterol?
Each 10 mg/dl of total cholesterol increases the risk of CHD by 10%
What constitutes a patient as high risk for CAD?
Hx of: CAD MI Stroke CHD
What constitutes a patient as intermediate risk?
2+ Risk Factors
What constitutes a patient as low risk?
<2 Risk Factors
HDL
Good cholesterol
High Density
LDL
Bad Cholesterol
Low Density
Treatment for Hyperlipidemia
Diet Exercise Weight loss Smoking cessation Aspirin therapy Rx if needed
Benefit of HDL
If HDL>60, it subtracts a risk factor.
Niacin
Lipid-lowering
Causes flushing due to prostaglandins
Intolerance is common
Cholestyramine, Colesevelam, and Colestipol
Bind bile acids
Lowers LDL
GI issues are common
HMG-CoA reductase inhibitors are more commonly referred to as?
Statins
HMG-CoA reductase inhibitors (statins) mechanism
Work by inhibiting the rate-limiting enzyme in the formation of cholesterol
Gemfibrozil
Fibrate (PPAR-alpha) agonists):
Lowers LDL and HDL
Reduces CHD
Ezetimibe
Inhibits cholesterol transporter
Lowers LDL
inhibits cholesterol absorption in the small bowel
Side Effects of Statins (HMG-CoA Reductase Inhibitors
Muscle aches
Mild GI issues
Liver toxicity
